The Tank Pressure Gauge is useful when trying to determine the pressure of a tank.
Rather than hunt down a regulator with a pressure gauge attached, divers can more quickly use the Tank Pressure Gauge. A small, handheld gauge, it fits easily in a tool box or save-a-dive kit. Standard with a DIN fitting, the guage gives pressure in both BAR and PSI.
A simple, twist collar makes it east to bleed off pressure.
