A digital pressure gauge is a must for accurate, repeatable and reliable gas blending applications. The DGX Digital Cylinder Pressure Checker uses a 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 (psi) and metric (bar) units of measurement. Corrosion resistant compatibility with all gases commonly seen in the SCUBA industry: Air, Nitrox, Oxygen, Trimix, and Helium. The wetted surfaces are stainless steel on the gauge plus chromed brass on the DIN fitting and are Nitrox Ready. Nice feature of the Dive Gear Express version is the bidirectional pressure bleed is a rotating collar on the stem, so there is no bleed screw to lose.

Easy to use: (1) Power on the gauge and 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. The gauge has a battery saver mode and will automatically shut off the display after 3 minutes.

Key Features:

  • Bidirectional rotating collar pressure bleed, so there is no bleed screw to lose
  • DIN fitting compatible with both 200-Bar and 300-Bar SCUBA valves, uses standard #112 viton O-ring
  • Easy-to-read 4-digit LCD display w/backlight - Push-button controls
  • User selectable units of measure: PSI, BAR, or MPA (kg/cm2)
  • Range 5 to 5000 PSI with accuracy better than ±1% full scale (±3 @ 300 psi, ±30 at 3000 psi)
  • Auto zero and maximum peak pressure memory recall and reset
  • 2.5" Thermoplastic housing with rubber boot, NEMA 4X weatherproof
  • Battery saver automatically shuts off the display after 3 minutes
  • Requires one standard 9V alkaline battery

The industrial housing is rated NEMA 4x weatherproof and resists corrosion but is NOT rated as IP68 waterproof. Do NOT submerge and avoid storage open to marine or high moisture environments. Remove the 9V alkaline battery for long term storage.

Units of Pressure in Diving

Globally there are a great many derived units of measurement for pressure in wide use, although pressure is often expressed as a force per unit area. The unit of pressure most familiar to divers in the US is pounds per square inch (psi), while bar is widely used by divers in the European Union. Many divers accustomed to the metric system are surprised to learn that bar is an archaic unit of measurement for pressure that is deprecated, replaced by the Pascal.

There is no convenient order-of-magnitude equivalent to bar in Pascal (Pa), the closest being one bar is exactly 100 kiloPascal (kPa). Expressed as force per unit area, one bar is ≈1.02 kilograms per square centimeter (kg/cm2) in the metric system, which is pretty close. Many divers think about pressure in terms of height of a column of sea water: one bar is defined as exactly 10 meters of sea water (msw) or ≈32.6 feet of sea water (fsw). Some partial pressure diving calculations are more convenient when performed using a unit of pressure known as atmospheres (atm): one atm is ≈1.01 bar or ≈14.7 psi. Given the relative accuracy of the diving devices we are using for measurement these are close enough that we've seen many divers interchangeably use 1 bar, 1 atm, 1 kg/cm2, 15 psi, 10 msw and 33 fsw as all equivalent, although this may distress the scientists and engineers among us.
