These rugged quality SPGs are graduated in 100-psi increments (Imperial) or in 10-bar increments (Metric). They are configured as just the bare gauge with no boot and no hose.
LOOK CLOSELY! A common mistake is ordering the wrong SPG, especially PSI or BAR.

  • Available in PSI or Bar graduations, white or black face

Many experienced divers prefer their SPG's to have an uncluttered face with easy to read graduations and without a boot. Coloring behind the graduations, typical of most designs, can make it more difficult to read, especially in the low range. However, the clean design of our naked gauges is very easy to read across the entire range. They feature chrome-plated all brass housing with a tempered mineral glass face and beryllium copper coiled Bourdon tube mechanism incorporating rack and pinion movement (aka 'pinned') providing the greatest degree of accuracy and reliability. The luminescent dial glows-in-the-dark, making it easier to read in low light situations. All these pressure gauges are suitable for oxygen service and include an over pressure relief plug. Available in these two sizes and your choice of PSI or BAR:

  • Chrome-plated all brass housing
  • Tempered mineral glass face cover
  • Bourdon tube mechanism with rack and pinion movement
  • Large { 2.25 in | 6 cm } diameter with { 2 in | 5.1 cm } face and { 1 in | 2.5 cm } thickness
  • Medium { 2 in | 5 cm } diameter with { 1.75 in | 4.5 cm } face and { 1 in | 2.5 cm } thickness
  • Available in PSI or Bar graduations, white or black face

Note these popular gauges are sold under a variety of brand names, but are all manufactured by Termo Industria in Italy.

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.

    I have purchased a number of these gauges from DGX over the years, they are easy to read underwater, rugged and just the right size, so that makes them a top purchase as far as I am concerned

    Purchased this SPG in July 2015 and it worked well until December 2017, however only about 20 dives. I imagine it took a pretty hard hit, the gauge became unreliable - showing about 500 psi lower than what other gauges showed. Didn't have it in a protective boot, just the bare gauge. Easy to read always and the glass never scratched.

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}.
