  • Magnetoresistive Milligauss Meter

    MR3 - Alpha Lab, Inc.

    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.

  • DC Gaussmeter

    GM1-HS - Alpha Lab, Inc.

    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.

  • DC Gaussmeter

    GM1-ST - Alpha Lab, Inc.

    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.

  • DC Milligauss Meter

    MGM - Alpha Lab, Inc.

    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.

  • Earth Magnetometer

    EM2 - Alpha Lab, Inc.

    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.

  • Gaussmeter

    GM2 - Alpha Lab, Inc.

    The Model GM2 Measures the strength and polarity of magnetic field up to 30kG when using a standard probes, or 800 gauss (resolution 0.01 gauss) if an HS probe is used. Functions include DC, AC and peak hold along with a user-adjustable alarm which has three modes of operation. DC background field can be subtracted out either by pressing "Relative Zero" or by manually adjusting the offset. The meter includes battery, AC adapter analog output jack and calibration certificate. If a standard probe is used, resolution is 0.1 gauss up to 19,999.9 gauss, which is stronger than the field of any permanent magnet. This 5 digit display allows measurement of tiny difference in strong fields. Above 20kG the meter autoranges to a 30kG range.

  • High Resistance Meter

    HR2 - Alpha Lab, Inc.

    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.

  • Battery Impedance Meter

    Alpha Lab, Inc.

    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.

  • Air Ion Counter

    Alpha Lab, Inc.

    The Air Ion Counter is a handheld meter designed to measure ion density-- the number of ions per cubic centimeter (ions/cc) in air. It measures this number separately for positive and negative ions (+ and - ions are usually present simultaneously). This instrument is a true ion density meter, based on a Gerdien Tube (Gerdien Condenser) design, and it contains a fan which pulls air through the meter at a calibrated rate. The standard model measures up to 2 million ions/cc (for comparison, outdoor air typically has 100 to 1000 ions/cc, both + and -). The 2 million range is sufficient for almost all situations except for measuring very close to electric ionizers or strong radioactive sources.

  • Air Shipment Milligauss Meter

    Oersted Meter - Alpha Lab, Inc.

    The Air Shipment Milligauss Meter has been designed so that one person alone can be the tester, and do repackaging, if necessary, without moving from the area. The remote sensor, shown on the right side, is connected through a 15-foot cable to the control box (left). This control box is placed next to both the package and the tester (person) so the tester can manually rotate the shipment. The remote sensor is placed either 15 feet or 7 feet away, depending on which test is being done.

  • AC Electric Field Meter

    Alpha Lab, Inc.

    This meter measures AC electric field in the vertical direction (same direction as the long axis of the meter). It has a wide frequency range (40 Hz - 20 KHz) and high accuracy (+/-2% of reading +/- 1 count) with an electric field strength range of 19 999 V/m and resolution of 1 V/m. The sensor is in the top 1/3 of the meter.

  • AC Milligauss Meter

    UHS2 - Alpha Lab, Inc.

    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.

  • Natural Electromagnetic

    EM - Alpha Lab, Inc.

    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.

  • Ultra Stable Surface DC Volt Meter

    USSVM2 - Alpha Lab, Inc.

    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.

  • Power Line Meter

    Alpha Lab, Inc.

    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).
