ET30A circuit testers are used to test direct current voltages between 6 and 24 volts.

The Extech ET25 voltage tester is a compact sized AC/DC voltage tester. The tester checks for voltage from 80-250V AC/DC The Extech ET25 voltage tester is very easy to use: the neon indicator glows if the circuit is live.

The Extech ET20 safely tests voltage from 100 to 250V AC/DC.

The Extech DVA30 is the only two-in-one current/voltage detector designed for electrical testing.

The DV50 provides all of the benefits of a non-contact AC voltage detector with a convenient telescoping probe.

The Extech DV30 is a compact solution to detecting AC Voltage without contact.

The DV25 Non contact AC voltage detector has two ranges and a sensor tip that fits perfectly into wall outlets or against wire insulation

The DV24 Non contact AC voltage detector has a sensor tip that fits perfectly into wall outlets or against wire insulation

The Extech DV20 offers detection of AC Voltage with features like a built-in flashlight.

The Extech 542 features wireless USB interface capability, which allows data transmission to go directly to your PC in real time.
