WJL-6000PRO Refrigerant Leak Detector, Freon Leak Detector with UV & LED Light, Car AC Leak Detector Kit for HVAC & Auto, 0.14 oz/yr Sensitivity for R134a R22 R410A CFC Automotive Gas Finder

This meter is very good, very reliable and sensitive for the car AC test leak.

works as should. Used it a couple of time on my rental homes

Works well and detects leaks accurately. The LED light is a nice touch—just wish it came with batteries included.

Incredibly priced and quality is great.

I have an older car that was getting a little warmer over the summer, so I needed a tool that could find a Freon leak. I like to do my research first, so I checked Amazon reviews and other online sources. This tool kept popping up and was in a good price range. I decided to buy it and give it a try. When I received the tool, I was impressed by its quality and design. It was easy to use and had a clear display and sound. I followed the instructions and tested my car’s AC system. I was able to find the leak right away. It turned out to be the high Schrader valve. I fixed it and recharged my AC with Freon. Now my car is cool and comfortable again. I am very happy with this purchase. It saved me time and money that I would have spent on a professional service. It is an excellent and reliable tool for finding Freon leaks in older cars. I highly recommend it to anyone who has a similar problem.

Not very good product, I was next to the leak but detector never picked it up ,I had to use foamy water to find leak

Cheap and kinda works.

The unit does what it is supposed to do. After reading the negative reviews, it seems people do not read the user manual or understand how this device is supposed to work. If you want something that works and will help you find the leak without spending hundreds of dollars, this is the answer. My only negative is with the manual, but since I am not an HVAC tech my negative may not be relevant. The sensitivity levels are 1-5. Using it today I determined 1 is the least sensitive and 5 is the most sensitive. But nothing tells you what each sensitivity level equates to. When detecting, the display will go from 0 (not detecting) to 9 (I assume a 9, but I only saw a 7 today). But nothing tells me what each rate means. If the sensitivity is .14oz/year and I find a leak at a level of 5, is that 5 x .14 or .7oz/year? It is important to know to determine if a repair/replacement decision needs to be made asap or can wait. I have not been able to find the leak as of yet, but this device did help me determine was the HVAC Co was more interested in selling me a new system than finding and repairing the leak when my current system is only 8 years old. I checked where they indicated a leak, and of course, no leak and it appears to be coming from an area with minimal access.

A pesar que compre otro detector, este es inmejorable. Lo recomiendo.

No accurate let me open the dashboards of the car to check evaporator of my car a/c because it’s showing there is leaks too much sound with # but when i open the evaporator clear no signs of leaks so need a day to reset the dashboard

Not detecting the Halogen as claimed. The time given for return is two days only. It is also against the claimed clause.

ليس بالسيئ لكن ليس دقيق مرة بكشف التسريب

Works better than soap testing for leaks
