Figure 1. Tru Pointe Refrigerant Leak Detector

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.

Technical Characteristics

* 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.
