The TNLT-220 is a technological breakthrough in non-contact voltage detectors. By utilising state of-the-art electronic circuitry, StarLogix has developed a completely new design in voltage detection equipment. The patented ferro-electric detector and updated design techniques maximise reliability and long life, and provide increased safety for todays electrical personnel. Static Discriminator technology exclusive in TNLT-220 provides more reliable detection on low voltage ranges, and ensures no more false alarms. This makes the TNLT-220, the first non-contact voltage detector suitable for patrolmen work and detecting pole leakage.
