Leak Detectors

Use our reliable leak detection equipment to perform pressure, vacuum and electrical leakage identification, as well as preventive maintenance. We offer detectors that convert ultrasonic signals into displayable and audible output. With our pistol-style devices, you’ll be able to quickly locate gas leaks or electrical discharge around conductors. At Transcat, you’ll find ultrasonic inspection systems and leak detection kits built by U.E. Systems, Megger, Amprobe and other manufacturers of advanced technology. Depending upon the model, you can locate or prevent costly problems on mechanical, electrical or fluid systems.
