  • UHS2 - AC Milligauss Meter

    Company: Alpha Lab

    The optional output is a 1/8" (3.5 mm) phone jack (mono), which is similar to the jack for headphones. A plug is also supplied which has two bare wires to connect to your data acquisition system or oscilloscope. The output is a slowly-varying signal (1/4 second response time) proportional to whatever the display is reading at the time. It is positive only. An output of 2 V corresponds to full scale (1999.99 milligauss) and 0 mV corresponds to 0 field.

  • EM2 - Earth Magnetometer

    Company: Alpha Lab

    The Earth Magnetometer Model EM2 measures small variations from location to location in the Earth magnetic field associated with buried magnetic masses. Unlike metal detectors, a magnetometer signal is not attenuated by rock, dirt, mud or water, so targets can be detected at great depth. (If D is the diameter of a mass of magnetizable material, the EM2 can detect it as deep as 40 times the diameter D, whether the mass is specifically magnetized or not.) It is the lightest weight and lowest cost magnetometer available which can reliably measure differences down to 1 nT from point to point.

  • GM1-HS - DC Gaussmeter

    Company: Alpha Lab

    The Model GM1-HS measures the strength and polarity of magnetic fields up to 799.99 gauss. The thin sensor is at the end of a 100 cm flexible cable. The sensor tip is also flexible and can be bent for a variety of situations. The sensor can be held against the surface of a steel part to check for residual magnetism, or it can be bent into an "L" shape to measure inside a DC Solenoid. This meter has a resolution of .01 gauss (1/50 of the Earth's typical field) which is finer resolution than the Model GM1-ST. It is also used to map fields from large magnets (If fields are over 800 gauss, use the Model GM1-ST). The meter has immediate turn-on and updates 4 times a second. There is no setup required, making this the fastest gaussmeter available.

  • GM1-ST - DC Gaussmeter

    Company: Alpha Lab

    The Model 1-ST measures strength and polarity of magnetic fields up to 19,999.9 gauss. The sensor can easily fit in a .060 inch (1.5 mm) gap and is at the end of a 100 cm flexible cable. The sensor end can be bent if required for a variety of situations. Place the sensor on a magnet face to measure the field. With a resolution of 0.1 gauss, it can measure any tiny variation from magnet to magnet or it can detect if a given magnet has lost even a little strength. Bend the sensor in to a "L" to measure inside a DC solenoid tube. The 5 digit display requires neither auto nor manual range change, making it easier to use than older style 3 or 4 digit meters. Turn on the meter and immediately begin reading fields (updates 4 times per second). There is no setup required, making this the fastest, easiest gaussmeter available.

  • MGM - DC Milligauss Meter

    Company: Alpha Lab

    An improvement on the flux gate magnetometer, the DC Milligauss Meter measures magnetic fields (technically "flux density") up to several times the strength of the Earth field. It has a resolution of 0.01 milligauss (1 nanotesla) and a range of +/-2000 milligauss (200 microteslas). The meter's magnetoresistive sensor is a major improvement over an uncompensated fluxgate magnetometer both in cost and stability. In fact, this sensor approaches a proton precession magnetometer in temperature stability. However, at only 1 mm x 0.2 mm, the active sensor area is much smaller than fluxgate magnetometer or proton sensors. This allows very precise magnetic measurements in small areas (such as thin films) or with high gradients, when necessary.

  • Battery Impedance Meter

    Company: Alpha Lab

    Operation is fast and simple. Just press the spring-loaded probes onto the two poles of the battery. After 1.5 seconds, the unit beeps (indicating good contact) and displays the battery voltage and either the number of siemens or milliohms, depending on the knob setting. The display continues to show these numbers after the probes are removed; it resets only when the probes are pressed onto the next battery. The impedance and voltage of any battery between 1.2 and 60 volts can be read. Because of the wide range of voltages, even single low-voltage cells, such as NiMH, can be measured. The manufacturers of some batteries specify impedance in milliohms while other specify in siemens (one divided by the resistance in ohms). This meter will display both types of impedance for any given battery. Accuracy is +/- 2% of the value.

  • HR2 - High Resistance Meter

    Company: Alpha Lab

    The Model HR2 meter measures resistance in nine ranges from 1 ohm to 1.9999 Tera ohms (1.9999x1012 ohms), and conductance in a single range of 0.00 to 199.99 pS (pico siemens, or pico mhos), all at low voltage of < 2 volts across the sample. Basic accuracy is +/- 2% of reading +/- 1 count. For resistance higher than 1.9999 Tera ohms, the conductance range can be used to measure conductance down to 0.01 pS (100 T ohms). The meter has a conductance range because samples with simultaneously high resistance and high capacitance settle faster to their final value on conductance (usually under one second), than on resistance (several seconds), and conductance is also capable of detecting higher resistance than the resistance ranges can. Note that resistance in units of T ohms is the inverse of conductance in pS, so that the resistance can be calculated from the conductance. For example, 100 pS is 0.01 T ohm (10 G ohm), and the highest readable conductance of 199.99 pS is essentially 5 G ohms.

  • EM - Natural Electromagnetic

    Company: Alpha Lab

    The TriField Natural EM Meter was designed to do field measurements for special research. It detects changes in extremely weak static (DC or "natural") electric and magnetic fields, and signals with both a tone and the movement of a needle-type gauge if either the electric or magnetic field changes from previous levels. A radio and microwave detector is also included, which reads radio power directly. Because man-made AC electric and magnetic fields are very common and could interfere with readings of static fields, the meter has been designed to ignore AC fields. Normal construction materials don't block magnetic fields, so the meter can be placed indoors and will work equally well, and due to the built-in tone, it can be used in the dark, and will sound the tone at whatever level of field the user sets. Model 1 operates on a standard 9-volt battery, and Model 2 runs on a 9-volt battery or an AC adapter (both included). Model 2 has an input jack for an optional high-sensitivity magnetic coil.

  • SVM2 - Surface DC Voltmeter

    Company: Alpha Lab

    The SVM2 has high sensitivity (resolution), and can detect even a 1 volt charge anywhere within its full range of +29,999 to -29,999 volts. Thus it is easy to measure whether a given process is increasing or decreasing the static electricity present, even if the increase or decrease is by a tiny fraction. The meter reads the actual static signal, but it also captures and stores the highest positive and highest negative signals that were experienced since the last time that the "Reset" button was pressed. These peak + and can be displayed at any later time. The peak function has a "window" time of 0.005 seconds (which is much faster than the display) so even very quick peaks are captured and stored. There is also a user-settable alarm. The alarm will sound if the signal (whether + or -) ever exceeds the value set by the user for at least 0.005 seconds. The alarm can be reset or muted at any time.

  • VGM - Vector/Magnitude Gaussmeter

    Company: Alpha Lab

    The Vector Gaussmeter displays the true magnitude of the field at any location as well as the X, Y, Z components of up to 800 gauss. Also separately displays peak values of X, Y, Z, and magnitude. There is a sound alarm that determines the locations where the field magnitude exceeds user-set threshold. Because magnitude is measured, the orientation of the sensor (E-W, N-S, and up-down) is not important; this is unlike a 1-axis gaussmeter. With the VGM the user can set the alarm to 15 gauss (for example) and it will sound (simultaneous with a red light) whenever the field exceeds 15 gauss for at least 5 milliseconds. Using the meter this way, it is easy to make a map of the 15 gauss line (or for whatever threshold is set) around a strong magnet. When using the alarm, of a steel part can be rapidly scanned to show if any areas exceed the set threshold. Then the "peak hold" function can be interrogated, showing the peak values of X, Y, Z (including polarity) and magnitude that occurred during the scan. Peak hold also has a 5 millisecond response time.

  • Voltage Touch Monitor

    Company: Alpha Lab

    The AlphaLab Voltage Touch Monitor enables personnel to identify voltage problems that usually remain hidden. The monitor reads the voltage on a finger (which is identical to the voltage at every other point on the body). It can detect as little as 1/10 volt in two modes: DC and AC/Spikes (ESD transients). In the DC mode, the displayed voltage is either positive or negative, and is usually very low if grounding is being worn and is functioning properly. Higher DC voltages (even while grounded) occur if a DC ionizer is blowing too close or if the person rubs against a high-static material or comes in contact with metal at a DC potential. If personal grounding is not being used, any DC signal can build up over time, and the DC mode continues to show the instantaneous body voltage as it changes. In the AC/Spikes mode, any transient voltage spike at least 1/2 millisecond long is temporarily displayed. If there are several consecutive spikes, only the highest is displayed, regardless of polarity. If the signal is a repetitive (AC) wave, the peak voltage is displayed, but always as a positive number. Even when proper grounding is worn, several tens of volts often occur with transients and AC. Maximum error for DC and AC is only 2% of the reading +/- 0.1 volt.

  • USSVM2 - Ultra Stable Surface DC Volt Meter

    Company: Alpha Lab

    The meter measures the magnitude and polarity of static charge on objects or surfaces. The sensor is calibrated for measuring a surface at 1" from the end of the sensor. On metallic or conductive surfaces, the meter measures the voltage on the surface. (As with any electrostatic voltmeter, the displayed reading depends somewhat on the size of the object being measured and the distance between the object and the sensor.) On insulating surfaces, "voltage" is not a well-defined number. In this case, the meter reads a number proportional to the static charge present.

  • 100XE - Trifield Meter

    Company: Alpha Lab

    The Trifield Meter is a gaussmeter, electric field meter, radio field strength meter in a single unit. When measuring electromagnetic fields (EMFs), the primary concern is usually magnetic fields, which can be tricky to measure. If a less sophisticated 1-axis gaussmeter is used, a reading of zero could result even where the field is strong. A 1-axis meter must be oriented correctly to measure the field (which is a vector). The 3-axis Trifield Meter solves that problem by measuring the true strength of the field regardless of which way it is oriented. Therefore, the Trifield Meter can be scanned rapidly across an area without having to stop at each point to search for the orientation that gives a maximum reading. Another section of the meter detects AC electric fields, which can exist independently of AC magnetic field. The third section detects radio/microwave, such as from a leaky microwave oven.

  • Power Line Meter

    Company: Alpha Lab

    The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 KHz 10 MHz (the frequency limits at which sensitivity is of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).

  • MR3 - Magnetoresistive Milligauss Meter

    Company: Alpha Lab

    The MR3 Magnetoresistive Milligauss Meter measures and displays the three vectorcomponents (X, Y, Z) as well as the magnitude (M) of the static magnetic field. Update is two times per second. The three sensors are in a 25 mm (1") cube at the end of a flexible 100 cm (40") cable. It can be powered by 4 AA batteries (included) or a Worldwide AC adaptor (included). It can collect and store data (X, Y, Z and M) for later download or stream data live via USB connector. Both the instantaneous values of X, Y, Z and M, and their peak values, are displayed on the meter screen. "Peak" values are the highest values seen since the peak reset button was pressed. Maximum error of sensitivity is +/- 0.5 % of the reading, and the maximum error of the offset is +/- 0.50 milligauss. Range is +/- 1999.99 milligauss with resolution 0.01 milligauss (or 1 nT) over the full range, displayed simultaneously for X, Y, Z and M.
