The PS-i is the world's first pocket size Full-Heterodyne Ultrasonic Leak Detector. The PS-i is capable of finding pressure and vacuum leaks in HVAC and compressed air systems, without being affected by wind or leaked refrigerants in confined spaces.
The PS-i can test a TXV (Thermal Expansion Valve) in minutes instead of hours.
Valued a lot LESS than the cost of a 1/16” hole at 90 PSI leaking compressed air for 7000 hours.
