HOYTMETER 277 HP — non-contact AC voltage detector (50 V – 132 kV)
The HOYTMETER 277 HP is a non-contact alternating-current (AC) voltage detector for detecting voltage in electrical conductors, equipment, sockets and switches. It works in two ranges — LOW (50 V – 1.5 kV) and HIGH (1.5 kV – 132 kV) — and alerts the operator with audible and visual signals; the signal frequency increases as you approach the voltage source. Lightweight and powered by a 9 V battery, it suits both industry and emergency services.
