Fieldpiece SRL8 Refrigerant Leak Detector ReviewsFieldpiece SRL8 Review

The SRL8 Fieldpiece refrigerant leak detector is a top-class diode sensor. It can quickly detect HCFC, HFC, CFC types of refrigerant leaks. No any other tool is more responsive to the leaks like the SRL8. Not only the professionals, but the beginners in the HVACR field also find this product more helpful, easy-to-use, safe, and cost-cutting.

From the traditional refrigerant leak detecting techniques like halide torches and bubble (soap) solutions, the heated diode sensor technology used in SRL8 will provide accurate results in almost all cases. It helps to detect the exact location of the leakage with more accuracy than the traditional methods.

Check some of the specifications and features of the SRL8 Fieldpiece Leak Detector below:

  1. It comes with a replaceable and rechargeable battery which can run up to 15 hours continuously after a full charge
  2. It complies with the latest SAE (Society of Automotive Engineers) standards by having three levels of sensitivity from 6.6oz/yr to <0.1oz/yr
  3. Ready to use in just 30 seconds after start which allows performing prompt operation
  4. Inbuilt LED display which shows you the amount of the battery left in the machine so you can charge it accordingly
  5. While in use, it sets to zero automatically after every two seconds. Although, you can manually set it to zero after the leak has been detected to point out other leaks

The small and ergonomic design of this impressive leak detector makes it fit comfortably in your hands. The rugged construction makes it extremely durable compared to other products in the same category.  

Let’s have a quick look at the pros and cons of the SRL8 leak detector.


  • LED & Audio alarm to help you detect links in dark as well as noisy environment
  • Capability to work while in vehicle or wall charging
  • Sturdy design of the probe helps you to make it steady where you want
  • You can turn the sound off to work silently
  • Faster working than the UV Dye
  • If you maintain it correctly, you can extend its life for more years than the shown five years
  • The flexible & non-conductive probe smoothly goes to the areas which are hard-to-rich
  • Quickly power up, and running capability allows you to finish multiple tasks in less time


  • In my tests, it did not provide satisfactory results while detecting R22 refrigerant leaks
  • It is designed in the United States but made in Taiwan. Though I do not doubt its quality, some users may not prefer to buy it as it is made outside the US
  • You may not be assured by the original manufacturer for the warranty of the product if you buy from the third party site

I do not like to advise you for having a second leak detector for a backup. But if you are detecting a refrigerant leak like R22 or H10, then it can be good to have the other machine with you, especially while at the job.

A few other Amazon customers also found the SRL8 as a great working heated diode machine for the refrigerant leak detection.

A few other users wrote that the sensor failed to detect the R22, H10 types of refrigerants which I already mentioned in the cons of SRL8.

Should you buy SRL8 Fieldpiece leak detector?

There is no doubt that the SRL8 diode sensor makes the HVACR technician’s job a lot easy, quick, safe, and productive.
