This is the most accurate pressure gauge available for gas blending applications. The DGX Digital Cylinder Pressure Checker uses the Ashcroft® DG25 digital pressure gauge and comes standard with a DIN connector that fits any SCUBA valve with a DIN fitting. If you have to check a tank with a K-valve, just spin on a DIN-to-Yoke Adapter. The very accurate digital gauge provides readings in imperial, metric as well as a few other (psi, bar, kg/cm2, kPa) units of measurement. Nice features of the Dive Gear Express version are the bidirectional pressure bleed is a rotating collar on the stem, so there is no bleed screw to lose, and the digital gauge body itself includes a rubber boot to improve shock resistance.

Easy to use: (1) screw the DIN fitting into the valve (2) rotate the bleed on the stem until it stops tightly closed (3) open the cylinder valve very slowly while turning your face away from the gauge (4) once the valve is fully open look at the pressure indicated (5) close the valve and rotate the bleed until the pressure begins to drain (6) once the pressure is completely drained unscrew the DIN fitting only using the collar.
