FEATURES:
-
Two-color LED light: The Freon tester comes with a UV lamp + flashlight. UV lamp is used with a fluorescent agent, and white light is suitable for illuminating dark and small places.

-
Upgraded version of WJL-6000: The WJL-6000Pro halogen leak detector is the upgraded version of the classic WJL-6000 with higher sensitivity. The new upgraded LCD screen displays sensitivity level and refrigerant gas leakage level, even with multiple alarm functions.

-
Higher sensitivity: 7.9-inch flexible sensing tip with higher sensitivity (up to 0.14oz/yr), compared with WJL-6000 (0.21oz/yr). It can continuously work for 50 hours with 4*AAA batteries supplied.

-
Multi-alarms: The audible and visual display alarms in the leakage tester can easily help you locate the leak. Once leaking gas is detected, the beep frequency will increase. The more gas leaked, the faster the buzzer beeps, and at the same time, the LCD screen displays the leakage level.

-
Visualization of leakage levels: The new upgraded LCD screen will display the leakage level of refrigerant gas. In addition, adjust the sensitivity by pressing the button, and the LCD screen will display the sensitivity level.

As an HVAC technician, I use this daily. The flexible probe reaches weird angles, and the dual alarms (sound + visual) make it impossible to miss leaks. Battery life is decent - lasts about a week with heavy use. Wish it came with a carrying case though.

Solid professional tool. The 7.9-inch probe reaches deep into units, and the multi-level alarm system is genius - you can literally hear how bad the leak is by the beep speed. My only suggestion? Make the buttons a bit bigger for us gloved technicians.

Perfect for DIYers! The instructions could be clearer, but once I figured out the sensitivity settings it worked like a charm. Detected a slow leak in my fridge that was driving up my electric bill. Paid for itself in one month!

Upgraded from the 6000 model and wow what a difference! The LCD screen showing leak levels is super helpful. Found 3 leaks in my home AC system that were too small for my old detector. The UV light works but you do need to use fluorescent dye for best results.

This detector saved me hours of work! The UV light feature is brilliant for pinpointing leaks in tight spaces. The sensitivity is way better than my old model - picked up a tiny leak my coworker's detector missed. Only gripe? The beeper gets kinda loud when it finds a big leak, but I guess that's the point!
