Product description

The SRL8 Heated Diode Refrigerant Leak Detector is designed exclusively to make the HVAC/R Technician's job easier, faster, safer and more efficient. We set out to develop the best heated diode leak detector for HVAC/R. We believe the SRL8 is it. It comes in kit form in a rugged, blow-mold case with all of the extras you don't get from the other guys.

• Triggers on all CFCs, HFCs, HCFCs and blends. More sensitive to some refrigerants than others.
• 15-hour rechargeable, user replaceable battery. It lasts almost two full workdays on a single charge (if your hunting down leaks all day). You can also use it while it's hooked up to the wall or vehicle charger.
• Filter system helps protect the sensor from moisture and other contaminants. The sensor is connected to the body at the other end of the snout. The filter is at the tip of the snout. If you accidentally hit some condensation or oil, the filter swells, shutting off the pull to the sensor and protecting it from failure.
• Manual or automatic zeroing. It auto zeros every two seconds until a leak triggers the sensor. After that you can manually zero the detector to help further pinpoint leaks.
• Up and running in 30 seconds. Some heated elements and corona discharge units take much more time to warm up. UV dyes can take several hours to travel through a running system and can degrade system components.

Answer:	No it won't, you will need a one that can pick up propane and butane. True branded reach in freezers has a kit you can request that has it.
Question:	Amazon ,this is for you ,,,on the product description you must include country of origin. i want to know if this is chinese made junk
Answer:	I am not Amazon. I am a consumer, and of course, it isn't made in the US. Sadly, near nothing is any more. It is made in Taiwan. Fieldpiece apparently recognizes consumer push-back since they say, "Designed in the US. Made in Taiwan."
Question:	Hello this equipment detects R12, R134A and R
Answer:	I would say yes I've had a hard time detecting r22 I used my other leak detector to find it

User questions & answers

Question:	Does this reallly detect r
Answer:	No good
Question:	can it detect gas leaks from my home kitchen
Answer:	It would probably work on a fridge or freezer in a kitchen. It might detect a propane leak (R290), but probably not natural gas leaks.
Question:	Does this unit detect r
Answer:	Yes. It does.
Question:	Does this work with r407c
Answer:	That is a hit or miss. I use it at work on many 407c systems and can usually pick up 407, but there is a lot of science behind why you may not be able to pick up a 407c leak. For example 407c along with all 400 series refrigerants are actually a blend of other chemicals. Each of those chemicals boil off at different temperatures. If your system has been leaking bad enough for long enough some of the chemicals the make 407c could now be gone and the ones left behind may not be detected by this detector. Best of luck to you.

Product features

Description:

LotFancy Freon Leak Detector detects all kinds of halogen refrigerants including but not limited to:

• CFCs e.g. R11, R12, R13, R113, R114, R500, R502, R503 etc.
• HCFCs e.g. R22, R123, R124, R401A, R401B, R402A, R403B, R408A, R409A, R414B, R416A etc.
• HFCs e.g. R23, R134a, R404A, R407C, R410A, R417A, R422A, R422B, R422D, R507, R508B etc.
• Blends such as AZ-50. HP62. MP39 etc.
• A2Ls

Wide Application:

1. Detects Ethylene Oxide gas leaks in hospital sterilizing equipment.
2. Detects SF-6 in high voltage circuit breakers.
3. Detects halogen gas and most gases which contain chlorine, fluorine, and bromine.
4. Detects cleaning agents used in dry cleaning applications.

Specification:

Flexible Probe:

• This Freon leak detector is designed with corona sensor so the probe should be very close to the gas leak area. Allows detection in difficult and hard-to-reach areas.
• Automatic Circuit: when the detector is in a measuring state, the automatic circuit will follow the changing level of halogen gas to avoid false alarm.

Real time sensitivity

• 7 Adjustable Sensitivity
• Refrigerant Freon Leak detector, with precise ultra-low power consumption IC design, can be automatically adjusted to the best optimum detecting state.
• LotFancy refrigerant Freon leak detector features an automatic circuit and a reset function that set itself to ignore the ambient level of Halogen gas.
• Reset： The leakage detector, upon initial switch-on, can automatically adjust itself to ignore the present level of Halogen gas in 6s and enter into the best state of detection. Place the sensing tip near a known leakage area and switch on, it's easy to find a higher concentration of leakage. Or move to the fresh air and turn on, adjust to the maximum sensitivity, any concentration above zero will be detected.

Leakage Warning

• When the gas leakage are discovered, "di di" sound will become more hurried. More refrigerant freon leak, more rapid. Meanwhile the indicator light flash quickly.
• The detector will beep regularly at a slow frequency when turn it on. If leak detected, it will beep in a higher frequency. (2 beeps per second when the detector is open, 10 beeps per second when detect the leak）

Notes:

Simple Operation Instruction

• Install 4 x AAA battery
• Turn the knob clockwise to turn on the leak detector, after 6 seconds, it turns into stand-by mode and begins to beep regularly. Then you can start detecting the leak.
