Pocket screwdriver tester for 100-250V circuits

The Tuff Stuff 96039 combines a 1/8" flat blade with an integrated electrical tester that detects AC and DC voltage from 100 to 250 volts. It is designed for electricians and technicians who need a compact tool for quick live-wire checks during installation or maintenance. The pocket format allows it to be carried alongside standard screwdrivers without adding bulk.

Passive detection with no batteries or heat

Because the tester draws its operating energy from the circuit under test, it produces no heat, emits no noise and places no load on a power supply. There are no moving parts, no fan and no internal power source to manage. The device is therefore silent and thermally neutral in normal use, requiring only contact with a live conductor to indicate voltage presence.

Questions about this item

How do I use the 1/8" flat blade on the 96039 to test a circuit?

Insert the blade into the outlet or terminal, then hold the metal clip or end cap to complete the circuit; the neon indicator lights if voltage between 100 and 250 V AC or DC is present.

What part of the 96039 tester wears out and needs replacement?

The internal neon lamp and its series resistor degrade over time; when the lamp no longer glows on a known live circuit the whole tester must be replaced.
