Hioki 3481-20 Voltage Detector

The Hioki 3481 is a pen-style, non-metallic contact voltage detector with a bright LED light that promotes safety and work efficiency even in dim worksites. When voltage is detected, the LED lights red along with an audio signal.

Safe, compact voltage detection with CAT IV (600 V) capability

Thanks to a compact, lightweight design, it’s easy to use this instrument anywhere. The absence of any exposed metal in the sensor enables safe measurement.

Light designed to facilitate use in dim locations

The tip of the instrument incorporates a light, which is convenient when you need to check area being measured or your work area when it’s dark.

Functionality for adjusting sensitivity based on the operating environment

The instrument’s detection sensitivity can be adjusted within the range of 40 V to 80 V AC.

Operating voltage range

40 V to 600 V AC (When brought into contact with a 2 mm^2 insulated cable equivalent to 600 V polyvinyl chloride insulated wire)

Maximum sensitivity variable range 40 V to 80 V AC (80 V at the time of shipment)
