The CPS Products LS1 Leak Seeker Electronic Leak Detector proudly introduces a new generation of leak detectors featuring a revolutionary new E_MOS detection technology. Laboratory and field tests have confirmed Leak-Seekers made using this new technology are more sensitive, stable, and accurate then any other detection method on the market including heated diode, infrared, corona, ultrasonic, halide torches and soap bubbles. With the Progressive Alarm Mode, the alarm pitch and number of lighted LEDs progressively increase as the leak source is approached, which allows searching for a broad range of leak sizes.
