  • 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.

  • Gauss Meters

    PCE Instruments

    A gauss meter displays electromagnetic wave measurements in Gauss (G), milliGauss (mG), milliTesla (mT) or microTesla (µT) units. A gauss meter can detect either static (DC) permanent (rare-earth) magnetic or dynamic (AC) electromagnetic fields (EMFs), or both. Thus, it is important to review the specifications of a gauss meter prior to purchase to ensure suitability for the intended application.Neodymium (NdFeB) permanent magnets are among the world's strongest and most widely used magnets. When testing magnets made of neodymium or other rare-earth elements, a gaussmeter or magnetometer capable of measuring DC magnetic fields is required. However, most electromagnetic fields encountered are generated by AC currents. Examples include electrical power lines, transformers and wiring for overhead lighting, solar panels and other electrical devices and equipment. Electromagnetic fields from electrical installations are believed to cause feelings of nervousness, anxiety and paranoia in EMF-sensitive human beings.Most gaussmeters offered by PCE Instruments can be calibrated and certified according to DIN ISO 9000 standards for an additional fee. Replacement gaussmeter probes and optional accessories are available for most gaussmeter models.

  • Automated Connector Tester

    Get Control, Inc.

    GCI's Automated Connector Tester is a self-contained test bench providing reliable testing of filtered and non-filtered electrical connectors. The ACT automates the tedious process of testing each pin against all others and shell for DC and AC leakage. For filter connectors, the ACT accurately measures pin-to-shell capacitance. For pins protected by diodes, the ACT provides leakage and breakdown measurements. The ACT also verifies pins which are intentionally shorted to each other or to the shell.
