Introduction
The Tru Pointe Refrigerant Leak Detector (Figure 1) is a portable, battery
powered instrument designed to pinpoint the location of refrigerant leaks
in air con di tion ing and re frig er ant sys tems, chillers, or cold storage units.
The use of heated-diode sensor technology allows the instrument to be
quickly responsive to all refrigerants, even when high background levels
of refrigerant vapors are present. No man u al sensitivity adjustments are
necessary during the inspection pro cess.
The instrument is suitable for HVAC Service Technicians, Refrigerant
Ser vice Technicians, Plant Maintenance Departments, Automotive Service
Facilities, and Refrigerant & Environmental Chamber Man u fac tures who
are in need of a small, lightweight and rugged instrument that is capable of
detecting and then pinpointing small to large gas leaks in tight spaces such
as those found in refrigeration units and automobile engine compartments.

Technical Characteristics
Tru Pointe
Technical Characteristics
Power .......................................... Two ‘D’ Alkaline Batteries
Warm-Up Time ..........................10 seconds
Refrigerants Detected ................ All CFC, HCFC and HFC refrigerants
including: R-12, R-22, R-123, R-134a and
blends R-404A, R-408A, R-409A, and
R-410A
Sensor:
Type ......................................... Heated Diode, Dispersive Electron, Plug-In
Life Expectancy* ..................... Typically 150 hours or 1 year of normal use
Battery Life ................................ 11 hours min. high sensitivity mode,
20 hours min. low sensitivity mode,
as tested using Duracell Ultra MX1300
alkaline batteries
Response Time ...........................Instantaneous
Sensitivity................................... The instrument will detect a leak of at
least 0.5 oz/year (14 g/yr) as detected by
moving probe tip at 2" (50 mm) per sec-
ond, 0.2" (5 mm) above leak source. A leak
rate of less than 0.1 oz/year (3 g/yr) can
be de tect ed when probe tip is held steady
over leak source for at least 5 seconds.
Sensitivity Adjustment .............. Automatic
Weight ........................................ 1.16 lb (0.53 kg) w/ batteries
Size (excluding probe) ............... 2.12W x 9.5L x 2.4H inches
(53.8 x 241.3 x 61.0 mm)
Probe Length .............................. 14" (356 mm)
* Caution: Exposing the sensor to a steady stream of highly concentrated
refrigerant will severely reduce sensor life or damage the sensor.
Sensor life is directly proportional to the amount of refrigerant
that passes through the sensor.
