LC-189B Manometer(30Psi), Digital Differential Pressure Gauge,Large Range Measurement, with Backlight Display, Suitable for HVAC Measurement, Gas Pressure System troubleshooting

Its a cheap unit, but works ok. The hoses are so small, they work ok with the provided adapter but will be more difficult to use otherwise.

I Used this to measure the pressure drop inside my house whenever I turn on my blower fan and it reads very accurately and no calibration needed and it shows in any unit you want. Furthermore, i also records the max value which is very usefull

My box only came with one tube and fitting, whereas the photos shows two of each. That being said, it is a good little tool that works pretty well!

The LYCEBELL Professional Air Pressure Meter has been a game-changer for me in ensuring accurate air pressure readings. As a DIY enthusiast, this manometer has proven to be a reliable tool for various projects. Its professional build and easy-to-read display make it a must-have for anyone working with pneumatic systems or inflatables. The durability and precision of this device make it a standout in its category, and I highly recommend it to professionals and hobbyists alike.

While this Manometer won't win any awards for overall build quality it does have a few things going for it:-a solid plastic body with what feels like a vinyl bumper-a large, bright, backlit display (backlight LEDs are white)-more units for pressure measurement than I knew existed-positive and negative pressure terminals are clearly labelled (could be better)-lots of functionality like detailed temperature measurement and simple controls that remind me of a multi-meterIt only goes up to a max of 3 PSI (look at the chart for conversion to other units) so you won't be using this except for specific low-pressure use cases.
