    PX-D102 - Photonix Technologies, Inc.

    The TECHLITE series of test sets allow fiber technicians to perform precise optical testing in the field. The meters, when operated in absolute power mode, are used to determine the level of optical power being emitted from a transmitter. In relative mode, the meters are used with the included source to perform fiber loss measurements or splice tuning operations. The TECHLITE meter, in relative measurement mode, will store the zero reference reading for all four wavelengths independently in non-volatile memory. This allows all zero references to be taken at one time and also allows the unit to be turned off while moving between locations preservebattery life. The TECHLITE meters utilize a graphic LCD screen to create unusually large and easy to read numbers as graphics to indicate power levels.

  • Surface Resistance Checker

    AS385 - Velleman, nv

    For Surface Resistivity Readings: Place the meter on the surface being tested and press the test button . If the LED showing 10^6. is illuminated, the surface being tested has a surface resistivity of 10^6 ohms per square or less. If the LED labeled insulative, is illuminated, the surface under test has a surface resistivity is greater than 10^12 ohms per square. (Be sure the ground wire is not connected through the ground jack when surface resistivity measurements.) For Resistance to Ground Readings: Place the meter on the surface being tested. Connect the meter to a known ground through the ground jack. When the ground wire is connected through the ground jack, the meter will not measure surface resistivity. Press the center button and the illuminated LED will indicate the resistance 10^5 ohms or less. If the LED shows insulative ,the resistance to ground of the surface under test is greater than 10^12 ohms.

  • Conductivity / TDS / Salinity

    Sper Scientific

    The amount of mineral and salt impurities in the water is called total dissolved solids (TDS). TDS shows how many units of impurities there are for one million units of water. One way to measure impurities in water is to measure the electric conductivity of water. Absolutely pure water is a poor conductor of electricity. Water shows significant conductivity when dissolved salts are present. Over most ranges, the amount of conductivity is directly proportional to the amount of salts dissolved in the water or Salinity. Four basic styles of Conductivity / TDS / Salinity meters are available for varying applications: Pens, Portable Meters, Data Loggers, and Benchtop meters.

  • Phase ID Systems

    Bierer & Associates, Inc

    LED Meter Probe allows the user to take Real time Phase Angle readings along with AC nominal voltage readings. A PD800W LED Meter Probe works in conjunction with the Receive Unit to verify phase identification along with the actual phase angle data. This is all done without any calculations or data transfer from the field to a base computer. The meter probe and reference probe or receive unit can operate at 100 feet of separation and up to 300 feet line of sight separation. In the event that this distance would need to be greater, the Receive Unit can be unplugged from the charging cable and taken into the field while operating on it's rechargeable batteries for up to 8 hours at a time.

  • 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.

  • 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.
