Content | 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. | 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 | With a full range of AC/DC current, AC/DC voltage, and frequency measurement functions for basic electrical troubleshooting, the AMP-220 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). | Compact yet tough, the Amprobe AM-510 autoranging digital multimeter delivers rugged, accurate performance for light commercial and advanced residential applications like rewiring an electrical panel, installing heated floors and light fixtures, troubleshooting and repairing home appliances, electrical sockets, and automotive electrical problems. Its CAT III safety rating and ease of use make it ideal for high voltage multimeter applications. Innovative digital multimeter features expedite go/no-go checks, and the built-in flashlight makes it easy to see wires and fuses in the dark. Plus a rubber tilt stand and a probe holder give you a ?third-hand? when you need it. | 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. |
