Introduction
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 conditioning and refrigerant systems, 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 manual sensitivity adjustments are
necessary during the inspection process.
The instrument is suitable for HVAC Service Technicians, Refrigerant
Service Technicians, Plant Maintenance Departments, Automotive Service
Facilities, and Refrigerant & Environmental Chamber Manufactures 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.
