Sweet Elitech Wjl 6000s Refrigerant Leak Detector

Elitech WJL-6000S Refrigerant Leak Detector features with high sensitivity and visualized alarm display. Its adjustable sensitivity ensures automatic and optimal detection status, locating leaks much more accurate. Its subtle structure, built-in high-precision stabilivolt IC and ultra-low power consumption circuit design enable much more stable operation and endurable batteries.
Features:
Upgraded 5 LED indicators reflect gas concentration.
Freon leak detector triggers on R22, R134A, R404a, R410A and all halogenated refrigerants including HFCs, CFCs, HCFCs and blends.
Adjustable Sensitivity; Maximum sensitivity is 0.21oz/yr.
Response within 3 seconds; Warm up in 6 seconds; Audible alarm and low battery indicator.
A flexible probe around 7.8-inch allows detections in difficult and hard-to-reach areas.
Audible alarm and low battery indicator:
This ac leak detector features with LED light flash and buzzer alarm. Note: Green flashes mean the battery voltage is normal, suitable for the job. Orange flashes mean the battery voltage is close to the limit work and needs to be replaced asap.
Once leaking gas is detected, the beep frequency will increase. The more gas leaked, the faster the buzzer beeps. The first indicator will flash quickly meantime and the other four LEDs will light up accordingly based on the concentration of leaked gases. The first indicator indicates both leak and battery level. Blinks in orange mean low battery. Note: 2 beeps per second when the detector is open, 10 beeps per second when the leak is detected)
This AC leak detector will respond to all halogenated gases. This includes,
CFCs e.g.R12, R11, R500, R503 etc.
HCFCs e.g. R22, R123, R124, R502 etc.
HFCs e.g. R134a, R404s, R125 etc.
Blends such as AZ-50. HP62. MP39 etc.
