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.
Technical details :-
Ultrasonic Leak Detector using Patented Heterodyne Translator.
Visual Output: 10 element bar graph with logarithmic response.
Capable of detecting a 5 psi leak out of a .005" (5/1000 inch) hole, 20 to 30 feet away depending on background noise.
Capable of detecting any gas that generates ultrasonic sound during flow including vacuum leaks.
Capable of detecting leaks equivalent to 3-4 oz./yr.It is not affected by wind or high concentrations of leaked gases refrigerants.
