When they say you get what you pay for I feel like the performance to cost was in my favor.

  • Nice tool to have
Style: Tester
My only complaint is that it does not come with fittings for the gas valve connection. Be aware that extra accessories will be needed to use this out of the box.

  • Make sure you have a snug fit with your tubing
Style: Tester
This is a basic unit that is simple to use and easy to read. I needed it to calibrate an ERV. I originally had a very hard time getting a stable reading and even using some stuffing around the tubing to make a better seal didn't help. I bought some natural latex tubing that had a better seal which made things much better and repeated readings were stable. The magnet in the back was very handy to affix the meter in a good location so my hands were free to make the adjustments. I have a second and bigger ERV to install but I'm confident that calibration will go smoothly. If I had to complain about something, it would be the case. It's pretty cheaply made and doesn't really have a good layout for the meter and tubing. But it does it's job. ... show more
