  • Great

  • Make sure you have a snug fit with your tubing
Size: One Size 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

  • This tool belongs and every trade person's toolbox.
Size: One Size Style: Tester
As an electrician, my expertise typically lies outside the realm of measuring air pressures. However, while working on industrial burners, I encountered a situation where verifying the safety circuit became paramount. In that instance, the precision of this meter not only proved invaluable but also justified its cost with just a single use. Its capabilities transformed a routine task into a critical safety check, ensuring that everything operated smoothly and securely. ... show more

  • OK, product, rather high price
Size: One Size Style: Tester
It reads in hundreds. It does seem to struggle to hold zero. Overall, the product Is OK. I’ve used it several times it works OK. I guess you can attribute the price to the brand name.

  • Magically repaired my heater
Size: One Size Style: Tester
Had a problem with my heater tripping from the pressure sensors not seeing enough draft. Got this to diagnose. Hooked it up with the 1900 feet of hose it comes with and measured pressure. Exactly where it’s supposed to be. Great. Waited around for the fault condition to occur: IT HAS NEVER OCCURRED AGAIN in 3 1/2 months! I, uh, just left it plumbed in and backed slowly away. Problem solved! ... show more
