The IDEAL 61-637 Single Range Non-Contact Voltage Tester is a reliable and essential safety tool for detecting the presence of voltage in the range of 24 - 1000V AC. This CAT IV 1000 V AC, UL Listed tester ensures safety and precision by automatically detecting and indicating the presence of voltage. It uses a non-contact detection system with an antenna enclosed in plastic at the tip, sensing the electromagnetic field around live conductors. When powered on, the tip illuminates with a green LED, switching to a red flashing LED and an audible beep that increases in frequency as the voltage level rises. Powered by two 1.5V AAA batteries, this tester also features a convenient LED flashlight in the tip, an audible disable function for quiet environments, a lanyard tie-off point, auto power off, and low battery indication. The 61-637 is designed to provide accurate and efficient voltage detection, making it an indispensable tool for any electrical professional.
