Review: Easy to use - Easy to use and read. Great instruction for use. From perspective of a DIYer so take that into consideration. My property consists of multiple buildings with many different gas (propane) appliances. This tool is great for installing and detecting. I use this tool to randomly check pressure at different locations looking for low pressures possible leaks. Simplicity of the tool makes installations quick and the peace of mind from random checks is a bonus.
Review: Very easy to use - This manometer is very well made, feels great in the hand (not slippery) and the buttons are very responsive and well positioned. The backlight makes it easy to read and stays lit for several seconds after turning it on. I was able to read gas pressure on my furnace quickly and easily. I am very happy with this instrument and it works well! The only thing I would change is the hoses are that come with it are very short, like a foot long. It could use a 3 or 4 foot long hose so you could set it on the floor or stand up with it to read it. Other than that, all good!

## Features

- Measuring Range: ±20.68 kPa / ±2.999 psi , Accuracy: ±0.3% FSO. repeatability error of only ±0.2%. Response Time: 0.5Seconds. Supports 12 units, including PSI, inHg, inH₂O, ftH₂O, etc., seamlessly adapting to local needs.
- Dual-Port Synchronous Detection: Real-time display of the pressure difference between two channels (P1-P2), particularly suitable for: HVAC duct pressure differential monitoring, filter blockage diagnosis, cleanroom micro-pressure control, maintenance and installation of blowers, clean rooms, boilers and other gas appliances.
