About This

[Precision Leak Detection For Multiple Refrigerants]: Wisscool AC/HVAC leak detector has 3 modes of sensitivity with maximum sensitivity up to 0.1oz./yr; with adjustable sensitivity level to find the locate leaks in various situations; The air conditioner leak detector has a warm-up time of 35 seconds and a response time of 3 seconds. It is compatible with a wide range of refrigerants, including HFCs(R134a, R410A, R404A, R507, R23, etc.); HCFCs(R22, R123, R124,etc); CFCs: (R12, R13, R502 etc.); PFCs(PFC-14, PFC-116, PFC-218 etc); HFO: R1234fy
[Colorful LED Design]: The pro-upgraded refrigerant leak detector LED screen can display the leakage level of refrigerant gas. In addition, the sensitivity can be adjusted by pressing the button.Also it provides real-time readings on sensitivity levels and leakage levels, ensuring effortless monitoring. Visualized leakage levels enhance detection accuracy for a more efficient operation
[Adjustable Alarm & Red Light]: Turning on the AC leak detector, it will emit a regular buzzing sound.Upon detecting a leak, the HVAC leak detector will make an urgent sound and the screen will display the leak level. Long press "MUTE" button turn on/off the buzzer.The flashing red light on the probe helps you find leaks even in narrow and dark places
[Lightweight & User-Friendly Design]: Compact, ergonomic build with three-buttons operation. Ideal for HVAC technicians and auto repair pros needing a portable Freon leak detector for on-site diagnostics. Longer 20 inch sensor probe allows access to difficult-to-reach areas
[Power-Saving and Long Life]: The HVAC refrigerant detector is equiped with 10000+ times bending tested detection probe and sensor life 1000 hours typical. Heated diode sensor brings upper precision compared to conventional sensors, making it effective for detecting different refrigerants
