2 Introduction
General Description
The Tru Pointe
®
Ultra Ultrasonic Leak Detector is an electronic instrument that detects the
inaudible high frequency sound (ultrasound) of high pressure leaks and converts it to sound a
human can hear. Using patented technology, the Tru Pointe
®
Ultra guides the user to a leak by
quantifying the intensity of the ultrasound and converting it to sound the user can easily hear.
The Tru Pointe ® Ultra has been speci fi cally designed for air conditioning and refrigeration
(HVAC-R) leak detection. The Tru Pointe ® Ultra is the only test system that can simultaneously
detect the vacuum and high pressure leaks that can occur in HVAC-R systems. Since the instru-
ment detects only sound, it is gas-independent and can be used to detect leaks at the speed of
sound, without the delay seen with gas dependent “sniffers.”

Features
• Capable of detecting a 5 psi leak from a .005” hole from 20-30 feet (depending on back-
ground noise.
• Capable of detecting any gas that generates ultrasonic sound during fl ow, including vacuum
leaks.
• Not affected by wind or high concentrations of leaked refrigerants.
• SoundBlaster ® allows testing of items not under pressure. (28-8010 only)
