H25-IR
Industrial Refrigerant Leak Detector
The H25-IR is an industrial leak detector used for low-
level detection and leak rate quantification of CFCs,
HFCs, HCFCs and halogen gas compounds that are used
in air conditioning and refrigeration equipment, fire
suppression systems, and various other residential,
commercial and industrial apparatus. The instrument
can be used to locate and quantify leaks as well as log
and totalize the entire group of leaks in a system to
ensure quality assurance compliance. The unit is
capable of detecting 29 of the most commonly used
refrigerants and halogen gas compounds.
F E AT U R E S & B E N E F I T S
• Utilizes infrared technology for detection which ensures
long sensor life and high accuracy
• Use of infrared technology enables response to
refrigerants only
• Responds to leaks in less than 1 second
• High sensitivity – detects leaks as small as 0.01 oz/yr
• Internal leak source enables calibrations to be made
quickly and easily
• Logging feature enables the total leak rate of a
system to be quantified quickly and easily
• 8 inch flexible probe enables leak checking in hard to
reach places
• Adjustable sensitivity ranges enable “nuisance” leaks
to be ignored by the unit
• Contains four relay outputs for external alarm control
• Contains 4-20 mA output current loop
• 2 Year Warranty
