Pressure test gauge 232 bar

The pressure test gauge is a system for checking the air pressure inside diving cylinders. The pressure test gauge must be connected to the connection on the cylinder to be tested. Pressure gauges comply with EN 837-1/3 standards for measuring instruments. Use an appropriate pressure test gauge depending on the cylinder connection and the pressure to be measured.
