Averaging, autoranging DMM with large digit LCD display and temperature function:

The Extech EX420 is a compact, 11-function autoranging digital multimeter. The EX420 measures AC/DC voltage and current, resistance, diode, continuity, and frequency, all with ±0. 3 percent basic accuracy. The EX420 can also capture Type K temperature readings. These numerous functions enable professionals to carry one meter into the field instead of several. Featuring a large, backlit LCD screen (4,000-count) with easy-to-read, 1-inch-tall digits, the EX420 provides high resolution over wide ranges, low current measuring down to 0.1 uA, as well as input fuse protection and misconnection warnings. Includes EX420 digital multimeter, CAT III test leads, multi-position tilt stand, Velcro hanging strap, holster with built-in test lead storage, Type K bead wire temperature probe, 9-volt battery, and user manual.
