The Extech EX830 clamp meter features a unique, built-in, non-contact Infrared thermometer with laser pointer to monitor temperature and locate hot spots on motors and electrical devices. A large 4000 count LCD display with bright back lighting allows you to see the reading in dim light. The ergonomically designed double-molded housing offers a better grip for one-hand operation. The 1.7 Ft. (43 mm) diameter jaw opening is large enough for conductors up to 750MCM. In addition to AC/DC current, it measures AC/DC voltage, resistance, temperature, capacitance, and frequency. It features: diode test, audible continuity beeper, min/max, data hold, auto power off, and a fast peak hold that captures inrush currents and transients.
