Identify circuit breakers fast and efficiently. | 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 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). | This versatile, easy-to-use digital multimeter is a great choice for homeowners or office maintenance staff. Use it to check for voltage in receptacles, extension cords, light fixtures, batteries, and other electrical circuits. Or check fuses, light bulbs, and continuity of electrical connections. You can even use it to verify the voltage level of automotive batteries and troubleshoot electrical problems in cars. With its user-friendly digital multimeter features like autoranging and a CAT III safety rating, the AM-500 will save time and increase measurement confidence. | 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. | 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. |
