Martindale Electric’s latest TEK100
and TEK 200 non-contact voltage
testers can detect voltages without
the need for physical conductor
contact in sockets, cables and circuit
breakers. Both have a built-in proving
device to continuously self check;
this activates the sensor in the tip of
the testers at 50Hz, and checks
battery and LED, to ensure the entire
circuit is tested.

Easy to use, the testers detect any
voltage between 100 and 600V AC.

TEK200 also detects the presence
and polarity of magnetic fields
produced by indicators, relays,
solenoids and transformers.
