Extech EX840A 1000A Clamp Meter with IR Thermometer - AC/DC

Extech EX840A 1000A Clamp Meter with IR Thermometer - AC/DC

The Extech EX840A Clamp Meter is a non-contact infrared thermometer designed specifically to measure temperature and detect hotspots on motors and electrical equipment. Its large 6000-count LCD display with bright backlighting makes readings easy to view, even in low-light conditions. The 43mm jaw opening accommodates conductors up to 750MCM or two 500MCM, and the double-molded housing ensures a secure, one-handed grip. With 1000A True RMS capability and a CAT IV 600V safety rating, the EX820A is a top choice for electricians, electrical contractors, and plant maintenance professionals.

The EX840A is able to measure both AC and DC current, wherease the EX820A can only measure AC current. Equipped with a Low Pass Filter for precise measurements in any environment and a Low Impedance Mode (LoZ) to minimize false readings from ghost voltages, the EX8xxA series is an excellent choice for professionals seeking reliable performance.
