HLD-200

I am not an HVAC professional, but I wanted something that would help me find refrigerant leaks and I didn't need an expensive sniffer. This product was the right price and had the sensitivity that I wanted. I checked this against a system I knew had a slow leak and it found the leak in a location I hadn't expected. When you hear an increase in beep frequency then you know something leaking there. A good item to have in your tool kit.

Indispensable pour détecter les fuites, je n'ai pas encore eu l'occasion de m'en servir.

Eficaz muy bueno

Only used once but it found my leak immediately with no problems or doubts as to where the leak was. Checked entire system and found both small (read tiny or minuscule) leaks in no time and with pinpoint accuracy. This is my first refrigerant leak detector but I doubt there’s any that are easier to operate and as accurate in this price range. It let me know I could have my A/C functional this summer without spending too much money and do a full repair later so it will be right for next summer and I won’t have to be adding Freon every couple of months like this year. And any A/C is better than none in the SE with humidity levels at 80 and sometimes 90%. Definitely a money saver if not a life saver for me.

Sensor worked very well to find tiny a/c leaks at connections in my vehicles a/c system, completely satisfied, saved a bundle.
