This DGX Dual gauge displays imperial and metric units simultaneously. It displays PSI in a white halo around the black center portion that display the BAR readings. Designed for high visibility in low light and no light conditions, the needle and ALL white markings are luminescent glow-in-the-dark. We have also limited the number of "tick" markings on the dial to make for a clean and easy-to-read face. The SPG's are otherwise identical to our white face and black face SPGs, manufactured by Termo with a chrome plated all brass housing with a tempered mineral glass face cover and a beryllium copper Bourdon tube mechanism incorporating a rack and pinion movement. Our naked SPGs include the spool, with two oxygen compatible o-rings, to mate the HP hose swivel to the gauge. All these pressure gauges are suitable for oxygen service and include an over pressure relief plug.

  • Chrome-plated all brass housing
  • Tempered mineral glass face cover
  • Bourdon tube mechanism with rack and pinion movement
  • Medium { 2 in | 5 cm } diameter with { 1.75 in | 4.5 cm } face and { 1 in | 2.5 cm } thickness
  • Includes both PSI and Bar graduations, on a white and black face
  • Includes air spool required for assembly to a hose

All high pressure hoses and SPGs use an 'air spool' with two tiny o-rings to mate the swivel connector on the hose to the fitting on the gauge. With a worn or missing air spool, any HP hose will LEAK at the swivel. The air spool is INCLUDED with this gauge and we strongly recommend replacing the air spool when replacing the gauge or hose.

    This is a solid and well-built SPG. It is great to have both scales. I would highly recommend this product. It would be nice if colour coded boots were available too.

    Another quality DGX product, but BAR gauge is difficult to read

    If I had to do all over again, I would purchase another thin gauge, which is my favorite for a stage bottle. It's rather difficult to read the BAR increments being they are so small, but that's my only ding on this product.

SPG Depth Ratings

The benchmark for SPG's in technical diving is the Italian made Termo Industria "Tech Gauge" (aka "brass & glass") model in two sizes with a dial that has been branded with logos of virtually every technical diving equipment supplier worldwide. Dive Gear Express sells it too, as our "DGX Premium SPG" with an uncluttered dial that does not have our logo on it. Termo specifications for their gauges only reference the European Union recreational EN250 standard, which essentially means all their gauges are officially rated by the manufacturer to the {164 fsw | 50 msw} depth of the standard. Regardless, technical divers have been taking the Termo brass & glass SPG to depths far beyond {330 fsw | 100 msw} without issue, for decades.

Termo Industria also makes a compact SPG model they call the "2K" and we sell it as our "DGX Thin SPG". The Thin SPG has a polycarbonate face cover held in place with a large O-ring seal. The thin gauge has an issue with depths significantly below {164 fsw | 50 msw}; it doesn't flood but you can't trust the indication either. What happens is water pressure causes the plastic face cover to depress slightly into the cavity of the gauge eventually touching and holding the needle against the dial so that it cannot move. When that is happening, the gauge reading as indicated by the needle is unreliable. Once you ascend, the cover returns to normal and the needle returns to normal indication as well. We don't recommend our "Thin SPG" for use significantly below {164 fsw | 50 msw}.
