Review on Unijin P251: Enhancing Accuracy in Pressure & Vacuum Measurements - Pressure Internals Testing & Inspection by Evan Hernandez
Accurate pressure gauge. Some liquid.
One of the two I ordered is defective. Scratched glass. They did a good job with the return/exchange. The liquid level was too low at all. I added some glycerin, it was easy to make. Not bad for this money. Very accurate.
- Robust construction
- No machine
