Elitech HVAC Refrigerant Leak Detector Heated Diode Sensor Halogen Freon Sniffer, Air Conditioning Detection, R22 R410A R134A R1234YF CFCs HCFCs HFCs, ILD-100H

This saved me from paying a shop to charge me an arm and a leg to fix my car AC. Found the leak right away and I managed to fix it myself. I wish I had bought one years ago.

Great option for the price. It's already paid for itself in finding two R134a automotive leaks and a 410a leak on my home AC unit. No complaints at all, it did exactly what I bought it for.

I use this for appliance refrigeration, it detects discharges of R600 several feet away and I haven't had it go off on just cabinet foam. Not sensitive enough for microleaks in the cabinet but it will work well for exposed leaks

Todavía no lo use realicé pruebas. Pero me hubiese gustado que traiga alguna funda o maletín de protección

nice product for the money.very sesitve in locating the leak.very happy with the product

I was hesitant to purchase this sniffer at first. I quickly located a small leak on a 4 ton 410A ADP evaporator coil the first day I used it. I really like the included backlight which assists in illuminating dye while performing a leak detection. Unit takes 20-30 seconds to warm up. Read out screen is surprisingly bright and high quality. Highly recommend!

Works great used it today for the first time to find a leak in a condenser and found it really quick.

Does not work very good. A known leak does not set off the sniffer.
