1. H-25C Halogen Leak Detector Applications
Coolant leaks adversely affect the performance of refrigeration and air conditioning equipment. Leak detection
is therefore one of the most important items of a quality inspection.
The H-25C Halogen Leak Detector is an instrument that will detect leaks of freon gases such as HFC 134a
and CFC 12, which are used as coolants in electric refrigerators, commercial freezers, and automotive air
conditioners.
This instrument is particularly suited for leak detection in manufacturing inspection processes.
Remarks:
HFC - 134a; Hydrofluorocarbon (R - 134a)
CFC - 12; Chlorofluorocarbon (R - 12)
Note: In this manual these will be hereafter written as R - 134a and R - 12.
2. Unpacking
and Initial Checks
Your H-25C Halogen Leak Detector was carefully inspected at the factory before shipment, and
packed so as to be highly resistant to damage while in transport. However, when you receive the
unit, please unpack it promptly and make a visual inspection to make sure that no damage has
occurred during shipment. Please also verify that the specifications of the instrument that you have
received match your order. To check the specifications, examine the model code information on the
nameplate at the rear of the instrument (see page 1 - 4 for the meanings of the codes).
