Good

The equipment has been very useful to us, to verify both positive and negative pressures, required in the operation of air quality measurement equipment.

I use this at work to dial in pressures on our pneumatic switches and valves. We are able to accurately set up pressure to a very specific pressure. We use Bar on the machine I use, but our supplier uses PSI. Easy to switch between unit of measurement. Nice travel and storage case. Love this, works so good

I got this meter so that I could check the pressure on my pool heaters gas valve. My heater has been making a whining whistling sound lately. I’ve narrowed it down to a high gas pressure problem by slightly closing down the gas shut off valve enough to keep a good sounding combustion and also stopping the whistle noise. The meter was able to correctly show me the pressure was too high. I set it to the proper water column inches and opened the gas valve fully. Yay no whistling! It works great and is easy to read and use. If you are new to using it I recommend watching a diy video to learn how to correctly use it. Obviously practice caution as gas is flammable and could ignite where you are working if you are not careful.
