Fifteen standalone high-pressure gauges for monitoring tank pressure during a dive. Three form factor lines: Mini 400bar (compact, five colour/scale variants), Standard 300bar (full-size dial, with and without thermometer), and Tek 300bar (braided hose, side-entry fitting for technical diving configuration). All variants are also available in 5000 PSI imperial scale. Nitrox/oxygen-compatible models and a replacement gauge head are also stocked.

The Mini 400bar series (SKU 501200–501205) is available in five versions: standard black surround (501200), all-black with fluo dial (501204), all-white (501203), pink (501205), and 5000 PSI imperial scale (501201). All Mini models use the same compact gauge head with a 400 bar scale appropriate for high-pressure steel cylinders up to 300 bar and aluminium cylinders. The Standard 300bar (SKU 501400) uses a larger dial face for maximum readability; the Standard thermo 300bar (SKU 501410) adds an integrated water thermometer. Both Standard variants are available in 5000 PSI scale (SKU 501401 and 501411). The Tek 300bar (SKU 501300) uses a braided high-pressure hose and a side-entry swivel fitting designed for technical diving configurations; available in 5000 PSI as SKU 501301. The Mini Oxygen/Nitrox 400bar (SKU 502100, also in 5000 PSI as 502101) uses oxygen-compatible internal materials and is required for nitrox mixes above 40% O₂. The Pony bottle gauge (SKU 501050) is a small dual-scale inline gauge for checking pony bottle pressure at the surface. The Head of gauge (SKU 501202) is a replacement Mini gauge head sold separately for integration into existing console housings.
What to Look For
- Mini 400bar for standard steel and aluminium cylinders. The 400bar scale covers all recreational cylinder working pressures up to 300 bar with room to spare. The compact form factor is practical as a standalone clip-on gauge or as the gauge element in a Mini console configuration. Colour variants allow identification and personalisation; the all-white and all-black versions provide different dial contrast preferences.
- Standard 300bar for maximum readability. The larger dial face of the Standard gauge provides more readable pressure increments, particularly in low-visibility conditions and when wearing thick gloves. If dive conditions regularly involve poor visibility, cold water, or heavy gloves, the Standard form factor is easier to read quickly underwater.
- Thermo variant if water temperature is relevant to your diving. The integrated thermometer on the thermo variants adds water temperature readout without requiring a separate instrument. Relevant for divers in variable thermal environments — thermocline diving, cold water diving, or dive sites with seasonal temperature variation.
- Nitrox gauge for enriched air service. The Mini Oxygen/Nitrox 400bar uses oxygen-compatible internal materials. This is required for cylinders with nitrox mixes above 40% O₂. If diving air or nitrox below 40%, a standard gauge is acceptable. Verify your gas mix before selecting gauge type.
- Tek 300bar for backmount and sidemount technical configurations. The braided hose and side-entry swivel fitting of the Tek gauge allow the gauge to be stowed alongside the cylinder or staged at the diver’s side without kinking. Standard rubber hoses do not flex as freely in tight routing configurations used in technical diving.
