Safe and easy-to-use The voltage detector designed for electrical testing Small and compact pen design for easy carrying Non-Contact Detection Voltage Sensitivity: 90~1000V AC (never test the voltage which is more than 1000AC) Operating Temperature : -10°C ~ 50°C Storage temperature: -10°C - 50°C Operating Humidity : 80% Cleaning: clean with damp cloth This instrument is only used to judge whether the conductor is live or not.
Power by: 2 x 1.5V AAA batteries ( Not included ) A necessary tool for everybody who works with electricity Ideal for testing AC cables, circuit breakers, wall sockets, junction boxes, fuses, etc. All outer surfaces are non-conductive for safety Fits in a shirt pocket for convenience All outer surfaces are non-conductive for safety Detects voltage without metallic contact Quickly locates the hot, neutral and ground terminals in any receptacle Touch the wire with the pen tip. If the red indicator lights up, it means voltage exist. Detects voltage without metallic contact. Size: 15.3 x 2.5 x 1.5 cm.
