The HHLT-2 refrigerant leak detector is a handheld device designed with a longlasting
solid electrolyte semiconductor
sensor can detect leaks of all commonly
used halogenated (chlorine or fluorinebased)
refrigerant gases. They include
HFCs (hydrofluorocarbons), CFCs
(chlorofluorocarbons) and HCFCs
Specifically, the instrument can detect:
• Widely used HFC refrigerants such as R-134a, R-410a, R-404a, R-407c and R-507
• CFC refrigerants such as CFC-12 (R-12)—commonly known as Freon
• HCFC replacement blends, such as R-22, approved by the U.S. EPA for complying with the stratospheric ozone protection provisions of the Clean Air Act
• R-1234yf, the newly approved hydrofluoroolefin (HFO) refrigerant with a global warming potential 335 times less than that of R-134a
Electronic Sensing is the Most Widely Used, Sensitive and Accurate Method of Refrigerant Leak Detection.
Why Look For Refrigerant Leaks?
There are three reasons to detect and repair leaks of refrigerant gases from
stationary and mobile air conditioners, refrigeration systems and heat pumps:
1. Leaks allow air and moisture to enter an A/C system or chiller. Moisture can
react with refrigerant to form corrosive acids and sludge that can damage a
compressor, plug up orifice tubes, and/or eat pinholes in evaporators and condensers.
2. Refrigerant is expensive. It may seem cheaper to keep recharging your system
with refrigerant than fix a leak—but it isn’t in the long run. And A/C systems
and chillers that aren’t fully charged won’t cool efficiently and thus waste
money (electricity-powered systems) or fuel (vehicle systems).
3. Most refrigerants deplete the ozone layer that blocks the sun’s harmful
ultraviolet radiation. In the U.S., the Clean Air Act of 1990 and later
amendments require owners or operators of refrigeration and air-conditioning
equipment with refrigerant charges greater than 50 pounds to repair leaks
within 30 days when those leaks result in the loss of more than 15% (comfort
cooling) or 35% (commercial cooling) of the charge over a 12-month period.
