Content | The Amprobe HD110C Heavy Duty Multimeter is designed for professional use in harsh environments. The meter is unusually rugged and reliable in everyday heavy use applications. Its made using waterproof construction to prevent dirt, grime and moisture from entering the case and causing inaccurate readings or damaging shorts. | The AM-560 autoranging digital multimeter is specifically designed for advanced HVAC applications. This HVAC multimeter offers a full set of professional digital multimeter features to measure a complete range of electrical parameters and key functions for HVAC applications. Dual thermocouples take differential temperature measurements; a low pass filter enhances accuracy on variable frequency drive measurements; and capacitance can be used to check motor startup capacitors. The AM-560 also features micro amps for flame sensor troubleshooting, non-contact voltage detection, and a CAT IV safety rating | Amprobe BAT-500 Battery Tester quickly and accurately tests batteries without taking the batteries off-line. This Battery Tester features a comparator function with pass/fail indication, and speed testing of batteries up to 500 Ah. Amprobe BAT-500 Battery Tester, compact and light weight, simultaneously measures battery resistance and voltage up to 40 V. | Amprobe AC68C TRMS 600 A Clamp Meter measures non-linear load current with true-rms readings. This top-of-the-line professional clamp DMM is CAT II 600 V, CAT III 300 V rated. | With a full range of AC current, AC/DC voltage, and frequency measurement functions for basic electrical troubleshooting, the AMP-210 clamp meter with its large backlit display is an excellent amp clamp meter choice. Rated CAT III 600 V, the AMP-210 clamp meter offers True-RMS sensing, fast response processor, non-contact voltage detection, capacitance, resistance and continuity measurements to enhance efficiency and safety in today?s complex electrical environments. The Amp-Tip function allows for precise measurement of current down to the tenth of an Amp, enabling accurate current measurement of both large and small diameter wires. A low pass filter allows measurement of current and voltage on variable frequency drives (motors with speed controlled by frequency). | Instant feedback with CO2 levels, with additional temperature and humidity measurement. Built in alarm warns against dangerous CO2 levels. The portable CO2-100 Air Quality meter is designed to measure air quality compliance in occupied spaces such as offices, production floors, schools or hospitals. |
