KEHIPI

KEHIPI Voltage Tester Dual Range 12-1000V LCD Buzzer Alarm

SKU CH-KPHQ-5FDER

Non-contact AC voltage tester with dual-range detection from 12 V to 1000 V, LCD percentage readout, buzzer alarm and CAT III 1000 V safety rating

  • Overall width4.2 in (10.7 cm)
  • Dual-range detection from 12 V to 1000 V AC covers low-voltage and mains circuits
  • CAT III 1000 V and CAT IV 600 V ratings provide professional-grade overvoltage protection
  • Visual and audible alerts change frequency and colour as voltage rises or proximity increases
  • LCD shows signal-strength percentage and bar graph for quick intensity assessment
  • Auto power-off after five minutes and low-battery indicator below 2.5 V extend battery life

Dual-range voltage detection

This non-contact tester covers AC voltages from 12 to 1000 V in high-sensitivity mode and from 70 to 1000 V in low-sensitivity mode. Electricians and homeowners can switch ranges with the S button to suit doorbell, thermostat or irrigation wiring. The NCV sensor lights the tip red and sounds a buzzer whenever voltage is present, while the LCD shows a bar graph and percentage value for signal strength.

Sustained detection behaviour

During continuous scanning the tip stays illuminated and the buzzer frequency rises as the sensed voltage increases or the probe moves closer to the source. The display alternates between red for live or high-voltage readings above 90 V and green for null-wire indications. Automatic power-off activates after five minutes without operation or signal detection to preserve the two 1.5 V AAA cells.

Thermals noise and power draw

The tester draws minimal current from its AAA supply and shows a low-battery symbol when voltage falls to 2.5 V, ceasing operation below 2.3 V. Audible alerts vary in pitch rather than volume, keeping noise low in normal use. Double-insulated construction meets IEC CAT III 1000 V and CAT IV 600 V ratings, and the 4.2 in body remains cool during extended operation.

Questions about this item

How loud is the buzzer alarm when the tester runs all day near live circuits?

The buzzer beeps at a higher frequency as sensed voltage increases or the tip gets closer to the source, and the tip flashes red; the screen turns red for high voltage or green for null wire.

What power source must I already have to operate this voltage tester?

It requires two 1.5 V AAA batteries; a low-battery symbol appears when voltage drops below 2.5 V and the unit shuts off below 2.3 V.

Will this tester work safely alongside my older CAT III 600 V rated tools?

It carries IEC CAT III 1000 V and CAT IV 600 V ratings and a high-voltage alert above 90 V, so it meets or exceeds the safety level of older CAT III 600 V equipment.
