The Extech EX411A offers multiple functions so you can carry one meter into the field instead of several. The manual-ranging EX411A measures AC/DC voltage and current, resistance, diode, and continuity, all with ±0.5% basic accuracy. The unit has low current capability, measuring down to 0.1 µA, and features input fuse protection and mis-connection warnings. A Type K thermometer is built in for surface or air temperature measurements. Comes with CAT III test leads, stand, hanging strap, holster with built-in test lead storage, Type K bead wire temperature probe, and one 9 V battery.
