## Questions & Answers

**Q: can the units be switched from psi to "WC?**
A: Yes I used mine for measuring LP gas pressures.

**Q: What is the thread size of the barb metal connector - 1/4 in. or 3/8 in?**
A: The hose Barbs appears to be molded into the housing, for the supplied 1/8" ID dia hose.

**Q: why are there 2 connector ports?**
A: Second port is for measuring differential pressure, not needed if only reading pressure, and there is a positive and negative.

**Q: Why does it read -.018"H2O without even taking the measurement? That would be quite an error.**
A: Because it hasn’t been “zero’d” yet.

### ⭐⭐⭐⭐⭐ Cheap piece of mind for heat exchanger diagnosis
*by T***M on November 4, 2025*

Worked great helping me diagnose a damaged heat exchanger in my furnace. Price was great!

### ⭐⭐⭐⭐⭐ Easy to use

Seems to be well made and accurate. Used it to test low side gas pressure on my 2 stage gas valve. Easy to read and use. Includes battery and tubing along with instructions. Make sure and zero the reading before taking your reading.

### ⭐⭐⭐⭐⭐ Works great for the DIY'er
*by S***N on December 12, 2025*

I had to change out the gas regulator in my furnace and needed a manometer to adjust it after. This worked great for that. I don't think I would buy this if I was a HVAC tech and used it everyday. But for someone like me who will use it once every year or two as a routine furnace check, or swapping a gas valve, this is perfect.
