AEMC 275HVD Non-Contact Voltage DetectorThe AEMC 275HD Non Contact High Voltage Detector is a high voltage detector by proximity. It is a product designed to warn the use of the presense of voltage in a particular work site. An eight position rotary switch selects the detection range. The AEMC 275HVD uses an internal sensor designed to detect the radiated electrical field (V m) present in energized conductors. The radiated electrical field increase with the line voltage but decrease with
