Content | 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 | Small size doesn?t mean small features. The Amprobe AMP-25 Mini-Clamp is pocket-sized, enabling quick and easy spot checks of electrical systems. With its rugged construction and CAT III 600 V rating, the AMP-25 is a must-have professional troubleshooting tool for commercial electricians and electrical contractors. The AMP-25 is designed to measure AC/DC load current and inrush current for motors. Essential features like True-RMS, non-contact voltage and low pass filter make this clamp stand tall next to clamps twice its size. With the AMP-25, you never have to sacrifice performance for size. | 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. | This CAT IV rated ACD-3300 IND Clamp On Tester is ideal for industrial applications and utilities that require an extra level of safety. Including True-rms sensing for accuracy, this clamp on meter?s extra large jaws can clamp on to those wide diameter wires making taking measurements in industrial environments simple. | Prevent unplanned downtime by detecting leakage currents with the ALC-110 Leakage Current Clamp. Rated CAT III 600 V to ensure electrical safety, the ALC-110 is designed to resist external magnetic fields for highly accurate readings. Features TRMS, a mechanical jaw lock, max readings and hold functions, highest resolution of 0.001 mA (measure up to 60 A), broad frequency range (15 Hz to 1 kHz), selectable filters (low pass, appliance, no filter), selectable limits (0.25 mA, 0.5 mA, 3.5 mA, 10 mA, 12 mA) and a battery-saving design. | 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. |
