Astro Pneumatic Tool Company Cordless Circuit Testers

Astro Pneumatic cordless circuit testers do not require a ground cable or clamp. Just touch something that acts as a ground (bare metal part on a car) and use the probe to test for power. They are safe to use on ECM sensors, transducers, air bags, and much more. Designed for use on DC-powered circuits with voltages between 3 and 28 V. The testers feature a specially designed V-tip needle that allows for safe piercing and prevents side slipping when piercing the wires' insulation. These circuit testers are manufactured from rugged chrome steel, and the unique V-tip can be removed to test those hard-to-reach places.
