5-90V LED Digital Voltage Tester

The LHDOS tester measures DC voltage from 5 to 90 volts and shows the reading on a bright LED digital display. A bidirectional LED indicates polarity with red for positive and green for negative. The tool is built from 45# steel and PVC and weighs 128 grams.

Technicians needing quick polarity checks

Suits mechanics and DIYers who want instant voltage and polarity confirmation on cars, trucks or SUVs. Not suited for buyers who need AC voltage measurement, high-voltage testing above 90 V or data logging capability.

Spring wire and alligator clip for reach

An extendable spring cord with an anti-bend strain relief and a large alligator clip lets one hand secure the ground while the probe reaches test points. The built-in protection chip guards the vehicle ECU from damage during testing. Powered by an internal battery, it requires no external supply.
