1. Fieldpiece


SRL8, Fieldpiece Heated Diode Refrigerant Leak Detector

Fieldpiece #ad - Manual or automatic zeroing. The filter is at the tip of the snout. You can also use it while it's hooked up to the wall or vehicle charger. It lasts almost two full workdays on a single charge if your hunting down leaks all day.

More sensitive to some refrigerants than others. Up and running in 30 seconds. 15-hour rechargeable, user replaceable battery. After that you can manually zero the detector to help further pinpoint leaks. Some heated elements and corona discharge units take much more time to warm up. It auto zeros every two seconds until a leak triggers the sensor. Triggers on all cfcs, hfcs, hcFCs and blends.

Uv dyes can take several hours to travel through a running system and can degrade system components. The sensor is connected to the body at the other end of the snout. Filter system helps protect the sensor from moisture and other contaminants. If you accidentally hit some condensation or oil, the filter swells, shutting off the pull to the sensor and protecting it from failure.
