1. Fieldpiece


SRL8, Fieldpiece Heated Diode Refrigerant Leak Detector

Fieldpiece #ad - Uv dyes can take several hours to travel through a running system and can degrade system components. Manual or automatic zeroing. It auto zeros every two seconds until a leak triggers the sensor. Triggers on all cfcs, hfcs, hcFCs and blends.

After that you can manually zero the detector to help further pinpoint leaks. The sensor is connected to the body at the other end of the snout. More sensitive to some refrigerants than others. You can also use it while it's hooked up to the wall or vehicle charger. Some heated elements and corona discharge units take much more time to warm up. Filter system helps protect the sensor from moisture and other contaminants.

Up and running in 30 seconds. 15-hour rechargeable, user replaceable battery. If you accidentally hit some condensation or oil, the filter swells, shutting off the pull to the sensor and protecting it from failure. The filter is at the tip of the snout. It lasts almost two full workdays on a single charge if your hunting down leaks all day.
