Amprobe ULD-420 Ultrasonic Leak Detector

Amprobe ULD 420

The Amprobe ULD-420 Ultrasonic Leak Detector is an advanced tool designed for detecting and locating leaks in compressed air systems, plumbing, refrigeration, and gas lines. Using ultrasonic technology, the ULD-420 can identify high-frequency sound waves generated by leaks, mechanical defects, or electrical discharge, converting them into audible signals that users can interpret to pinpoint problem areas. This device is highly valuable for professionals in HVAC, manufacturing, automotive, and utility industries where accurate leak detection is essential for preventing energy waste, equipment damage, and costly repairs.

The ULD 420 leverages ultrasonic technology to detect sound frequencies beyond the range of human hearing, typically in the range of 20 kHz to 90 kHz. This allows the device to identify leaks in pressurized systems, electrical discharges, and mechanical issues such as bearing wear or cavitation in industrial equipment.
