SRL8 – Heated Diode Refrigerant Leak Detector

Sensitive. Portable. Durable.

Where to Buy

  • Sensitivity better than 0.1 oz/year (3 grams/year)
  • 15-hour rechargeable lithium-ion battery with wall and vehicle chargers
  • Detects CFC, HFC, HCFC, and blends
  • Manual or automatic zeroing

One-of-a-kind by design.

We packed the SRL8 Heated Diode Refrigerant Leak Detector full of the features you need and designed it to handle the abuse that most leak detectors can’t handle. It also has a magnetic hanger that makes it easy to store when you’re not using it; but even with all these features, it still fits easily in your hand. 

Helps with every kind of leak.

The SRL8 detects CFCs, HFCs, HCFCs and blended refrigerants with superior sensitivity at detecting R410A refrigerant. It’s also equipped with a hydrophobic gas filter, preventing liquid ingress and protecting it from failure. Best yet, automatically or manually zero to refrigerant gas concentrations for full control to pinpoint leaks. 

Detects faster. Lasts longer.

The SRL8 boasts a 15-hour battery life that’ll last longer than hopefully you will have to be on the job site. Yes, it’s built to perform. Also, it’s up-and-running in 30 seconds, unlike other heated diodes and corona discharge units.

Every feature you’ll love:

  • Three sensitivity levels from 6.6oz/year to <0.1oz/year. Meets new SAE standards
  • Ruggedized boot that fits in your hand
  • Heated diode sensor lasts up to five years
  • Audible and visual alarm – turn the beep on or off when you want
  • 15-hour battery charge – work all day and all night on one charge
  • Battery life check – see how much charge you have left by looking at the LED display
  • Non-conductive, sturdy probe stays where you want it
  • LED and audio alerts help find leaks in noisy and dark environments
  • Mute button
  • Magnetic hanger

What’s Included:

  • (1) SRL8Advanced Refrigerant Leak Detector 
  • (5) RFL2 O-rings and 10 Replacement Filters 
  • (1)RFE2 9-inch Flex-Probe Extension 
  • (1) RRE2 Rigid Extension Probe 
  • (1) ABMK3 Blow-Molded Case

  • What is the difference between the SRL8 and SRL2K7?

      1. The SRL8 uses a heated diode sensor. The heated diode’s advantage is that it detects absolute concentration levels so it can be held on a leak and will continue to beep. It is also initially very sensitive. Its major disadvantages are that the sensor becomes less sensitive over life, eventually needing replacement and it is more sensitive to some refrigerants than others.
      2. The SRL2 uses an infrared (IR) sensor. It detects a CHANGE in concentration, so the wand must keep moving. The main advantages of the Fieldpiece IR sensor are that its sensitivity will remain the same over the life of the instrument, the sensor will last the lifetime of the instrument, it will not trigger on humidity or on oil, and it has nearly the same sensitivity to most refrigerants. The main disadvantage of infrared sensors is their sensitivity to mechanical disturbances.
  • Why won’t it stay on / why won’t it charge?

    • If no sensor is installed or the installed sensor is broken when the unit is turned on an alarm will sound and the unit will turn off.

  • How long does the sensor last?

    • If it seems like your leak detector is no longer picking up leaks or is not as sensitive as it was when you first bought it, try replacing the filter. This should fix the issue. If this does not fix the issue try replacing the sensor

  • How do I order a new sensor?

      1. Contact your local Fieldpiece supplier and have them order part number “RHD1”
      2. Carefully insert the new sensor and replace snoot. The sensor can be inserted in two different configurations, either of which will allow the SRL8 to function correctly.
  • Where is the sensor located?

    • To install or replace the sensor, make sure the unit is turned off. Then, unscrew the snoot on the SRL8 and if replacing gently pull the sensor from the base.
