Digital Manifold Gauge Set, Vacuum Pressure Temperature Leakage Tester for Air Conditioning Systems and Heat Pumps, HT-750

Relación precio producto es lo justo

I was excited to use this gauge, specifically for its ability to provide real time subcooling numbers. But I ran into some problems. First, if you plug in only one of the two temperature gauges it completely throws off the readings of the other. Second, with both sensor plugged in and after resting in the same spot for 10 minutes the temperature sensors provided ambient readings that were 4 degrees different. Same result if I swapped them. That temperature difference increased to 6 degrees when both were clamped side by side to the same liquid line. Finally, the valves leak unless you turn them pretty tight BUT, they are so flimsy that you will break the knob (it will just spin on the shaft) before you can fully seal the valve. Had to send it back and shop for a higher quality gauge.

The build quality for manifold is on par with the Testo 549. Really would have liked to have blue tooth on it. It sucks to have to scroll threw all the different refrigerants for the 3 I normally use. I havent figured out how to remove all the other ones. The hoses that come with it are total garbage one thing is they are like 2 foot long and the ends were threaded wrong

Unit looks nice, that’s about it. Sent wrong hose size, needed 1/4, but comes with 5/16 for the low and high side connection. I had to search all over town to get buy the correct size locally. Once connected, meter is giving me false readings. I don’t know if I got a lemon, but too mad to exchange for another. Thankfully Amazon has amazing return policies. I will be either buying a better brand like Testo or goes with an analog version.

Muy buen producto y rapida entrega lo recomiendo
