Sheffield Professional Cordless Computer-Safe Circuit Tester

Rugged Solid State electronic voltage detector needs no wire or clip connector to ground. Safe around automotive microcomputers, electronics control modules, sensors, etc.

Specifically designed for use on autos, trucks, trailers, RV's & boats.

Features:

No ground wire means no wire tangles nor time lost searching for grounding points.
High Impedance Electronic circuitry.
Safety V-groove needle accessory for piercing and carring.
Negligible Current Draw ( 20 micro-amps) is 10,000 times less than regular lamp type testers. This gives complete safety when working around sensitive electronic control modules and sensors.
