Review on 🔍 Enhanced Precision Testing and Inspection of Unijin P251 Pressure Internals by Shawn Quick

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.
