Product Information
Mares SPG52 Submersible Pressure Gauge is a technical diving instrument from the Mares XR Line, supplied with a 60 cm hose, oxygen cleaning compatible, and double welded so it can be worn without a protective cover. It reads cylinder pressure from 0 to 360 bar (0 to 5,000 psi) on a single, luminescent dial behind a tempered glass lens.
Who it is for
The SPG52 is built for technical divers and DIR-trained divers who want a simple, rugged gauge paired with a high quality regulator. Because it is oxygen cleaning compatible, it can be used with air or with mixtures containing high percentages of oxygen, and its beryllium copper Bourdon tube mechanism is designed to hold its calibration even after a strong impact, which matters on long technical or decompression dives.
Key details
- Graduation range: 0 to 360 bar / 0 to 5,000 psi, single reading
- Mechanism: beryllium copper Bourdon tube, impact resistant calibration
- Housing: brass with double mirror chrome plating, double welded for use without a protective cover
- Lens: tempered glass; dial: luminescent
- Hose: 60 cm rubber (article 414600)
- Gas compatibility: air or mixtures with high percentages of oxygen, oxygen cleaning compatible
- Certification: EN 250
Compatibility and sizing
This listing covers the 60 cm hose version (article 414600), available in BAR or PSI reading. Mares also publishes the SPG52 with a 15 cm Miflex hose and a 15 cm Miflex Oxygen hose as separate configurations within the XR Line, letting technical divers match hose length to their rig.
