The Tru Pointe Ultra is a low-cost handheld ultrasonic leak detector capable of finding leaks of any gas type, including refrigerants, air (compressed or vacuum) and nitrogen. The Tru Pointe Ultra can also be used for thermal expansion valves and steam traps, making it a very versatile leak detector. The Tru Pointe Ultra can detect leaks from a distance – as much as 20-30 feet. It is available with options like noise-cancelling headphones and the SoundBlaster®, an ultrasonic generator which can be useful when troubleshooting items that are not pressurized. It comes with a 1 year warranty.
