🔍 Enhanced Precision Testing and Inspection of Unijin P251 Pressure Internals Review

Seems to work fine. I have no way of knowing its accuracy without an independent sensor. What I would buy 2 to check the fit > It was bought because of the low price.

Gauges on my air compressor need replacing. They are well suited for this purpose and are of better quality than the original sensors. They are also larger and easier to read than the originals. Filling with liquid is said to help with the vibrations common to air compressors. Not that it matters, but they look better. They seem accurate enough for my purpose, but if I needed guaranteed accuracy I would go with a more expensive brand.

Everything worked as advertised, what can't say about the pressure gauge that came with my DIY Aquarium CO2 Generator Kit. The original pressure gauge never left the zero measuring pin. As soon as I installed this new pressure gauge and recharged the kit, it immediately started measuring pressure. This told me to adjust my mixture the next time I fill up as it was running at 10+ PSI when it should have been 2-4 PSI. I would buy it again if I need another one for future projects.
