FEATURES :
1. Telescopic, compact, light-weight
The length is elastic from 354mm to 1005mm, The equipment is
light-weight (180g), easy to handle, and handy to carry.
2. High-voltage detectable
The equipment, whether in stretched state is available for
voltage detection in high-tension circuits (3.3kV, 6.6kV and 24kV)
whether the wires involved are naked or insulated.
3. Low-voltage detectable
The equipment can be used for voltage detection in low-tension
circuits (80V ~ 600V) by holding the nameplate portion of the
detecting head. Before-use check can easily be done by
plugging in an AC 100V plug socket, without using a tester.
4. Easy to recognize indication
Intermittent lighting in red of a high intensity light-emitting diode
and intermittent audible sound of an electronic buzzer are readily
recognizable at a full daylight, noisy location.
5. Waterproof
The detecting head, being tightly enclosed, is free from any
trouble due to dust, dirt, water or the like.
