The Extech EX420 digital multimeter is a robust and reliable multimeter with an affordable price tag. The meter has switchable backlighting to conserve battery life and manual range selection. It measures AC/DC voltage and current plus resistance, diode test, continuity and temperature . It features very low current capability, measuring down to 0.1μA DC. For additional safety, it has input fuse protection and mis-connection warnings. This meter adds capacitance and frequency measurements compared to the more basic EX410 model. Supplied with CAT III test leads, multi-position tilt stand and velcro strap for hanging, protective holster with test lead holder, type-k thermocouple, and a 9V battery.
We also supply other meters from the Extech EX400 series; EX410 (57-6888), EX411 (51-8759), EX430 (51-8760), EX450 (57-6889), EX470 (51-8761). See the technical specification to decide which meter is for you.
