The Amprobe TMULD-300 ultrasonic leak detector with transmitter senses pressurized leaking gas, detects electrical arcing around switches and electrical panels, and finds failing solenoids, valves, and bearings in electrical automotive, and heating, ventilation, and air-conditioning (HVAC) maintenance applications. Pressurized gas leaks, electrical arcing, and failing solenoids, valves, or bearings emit ultrasonic frequencies, which the leak detector's ultrasonic sensor converts to an audible range that can be heard through the included headset. The detector comes with a transmitter that emits an ultrasonic frequency to help locate leaks, such as cracks or openings, that are not pressurized enough to emit frequencies the detector can pick up. The TMULD-300 leak detector detects any pressurized gas leaks, including chlorofluorocarbon (CFCs), hydro-fluorocarbon (HFCs), nitrogen (N), carbon dioxide (CO2), and steam. The presence of wind or airborne contaminants, such as refrigerants, does not affect its operation. The included parabola horn attaches to the probe to amplify the detected signal, allowing measurements to be taken at a distance and improving leak detection in noisy areas. An extension tube provides additional reach for access to remote leaks. A display panel with ten light-emitting diodes (LEDs) indicates when the sensor is close to the source of the leak. A low-battery indicator signals when the meter's batteries need to be replaced. The Amprobe TMULD-300 comes with a hard plastic carrying case that helps protect the leak detector from damage during transportation and storage. Amprobe began life in Long Island, NY in the late 1940's under the name Pyramid Instrument Company. In 1960 the company name was formally changed to Amprobe Instrument Corporation. Amprobe continued to design, engineer, manufacture and distribute product from its Lynbrook, NY location until it was merged to form ATP and relocated to South Florida in late 1999.
