HLD-100+

This helped me find the refrigerant leaks in the manifold hose and condenser of my car. I had to trace the entire A/C pathway. It's like a hound that starts beeping when it gets a "scent" and barks like crazy when the real leak is found. First vacuum your system good and then add about 20 to 25 PSI of refrigerant and then start sniffing. For my leaks normal sensitivity was good enough. TIP: if it gets to the point where the detector is going off constantly, power-off and/or reset it and used low pressure compressed air to gently blow the sensor head clean. If you find a significant leak this can quickly over saturate the sensor head and ring false positives when moved away from the leak point. If you have slow leaks and need more sensitivity, try cupping the sensor with your hand under the line or A/C component to concentrate the gas as you move slowly through the system. Be patience. Go slow. And think, that R-134a is heavier than air, so remember to trace upwards too to help find the real leak point when it starts beeping.

Unboxing was a pleasure...batteries included & 1 extra tip. Hit the on button, set your sensitivity & it's ready in just a few seconds. The one feature of this detector that sets it apart from other value items...the longer probe & is very flexible. I tested an active AC leak, that i was already aware of, and it picked it up right away. I'm an old Master technician & have used far more expensive detectors than this one...but bottom line is it works just the same...impressive purchase indeed.

Funciono perfectamente bien

Suppose this Elitech HLD-200 Plus helped me diagnose the ac issue on my '03 Taurus, and saved me A LOT of time and money! I had 2 worn out valve cores and the Elitech detected them very quickly. Tried cheap cores and problem persisted. Called Ford and got a couple OEM cores, now our ac is FREEZING us out! Going on 2 weeks and she's still blowing out 48 degree air! Would not have been possible to get ac back up and running this quickly without this phenomenal device, and believe me, I was skeptical! I resisted ordering for a day or two, poo-pooing my fathers suggestion... happy I finally listened and tried it! FYI, this model does come with a spare head (2 heads in total - as pictured).

Didn’t know what to expect, but really impressed. Checked indoor unit and did not find anything. Went to outdoor and detector went nuts down low. Traced leak to bottom pass of condenser had rubbed a hole. For what you pay for the more expensive this works great.

Item was exactly as described and was shipped fast and works very well, highly recommended seller

Sadly didnt work

It works found two leaks on 410a line
