KEHIPI

KEHIPI 5-90V Digital LED Electrical Tester 140 in Spring Wire

SKU CH-M37N-FYNPF

Digital LED tester reads 5-90 V DC on cars, trucks, motorcycles and boats with a 140-inch spring wire and alligator clip for one-handed reach

  • Width6.7056 in
  • Accurate DC voltage readings from 5 to 90 volts via digital LED display
  • Red and green visual indicators show positive or negative polarity instantly
  • 140 inch heat and oil resistant PU spring wire reaches around the whole vehicle
  • Sharp insulated stainless steel probe pierces wires in tight spaces without shorting
  • Shatter proof ABS body withstands heavy duty workshop use

Accurate DC Voltage Display

The KEHIPI electrical tester uses a digital LED readout to show DC voltage from 5 to 90 volts. The display remains clear in daylight or dim conditions. It suits technicians who need quick, reliable readings on vehicle electrical systems.

Visual Polarity Indicators

Red and green LEDs show whether the probed circuit is positive or negative ground. The alligator clip connects to either polarity for one-handed operation. The insulated stainless steel probe prevents accidental shorts while piercing wires in tight spaces.

140-Inch Spring Lead Flexibility

A heat and oil resistant PU spring wire stretches 140 inches so the tool reaches anywhere around a car, truck, motorcycle or boat. The ABS body resists shattering for long workshop life. Buyers needing higher voltage ranges or data logging will need a different instrument.

Questions about this item

How do I connect the alligator clamp and probe to test a circuit on my vehicle?

Clip the alligator clamp to either the positive or negative ground, then touch the stainless steel probe to the opposite side of the circuit. A red LED indicates positive voltage, while a green LED indicates negative ground.

What part of the tester is most likely to wear out first and need replacement?

The 140-inch PU spring wire is the main wear item; repeated stretching, heat exposure and oil contact can degrade the insulation or conductor over time.

At what voltage will the digital LED display stop giving a reading during prolonged testing?

The display is rated for 5-90V DC; sustained voltage above 90V will exceed the operating range and the tester will no longer show a valid reading.
