Aqualung SPG Pressure Gauge with Temperature

Aqualung SPG Pressure Gauge with Temperature

The Aqualung SPG with Temperature puts cylinder pressure and water temperature together on a dedicated analogue instrument. The luminous face gives you a simple pressure reference alongside a wrist computer, with a long HP hose for routing the gauge where it is comfortable to reach.

Features and benefits

• Mechanical pressure reading. A Swiss-made, shock-resistant Bourdon tube moves the pointer as cylinder pressure changes. The pressure indication works without a battery or wireless pairing.
• Temperature at the gauge. The integrated temperature display adds an environmental reference when you bring the instrument into view.
• Luminous face. The dial remains visible after light exposure, helping you distinguish the pointer and markings in reduced light.
• Room to route the hose. The supplied 36-inch HP hose gives flexibility in positioning the gauge. Secure the finished assembly so spare hose does not form a loose snagging loop.
• Pressure-relief provision. A one-way safety valve provides a route for unintended pressure inside the gauge housing to escape; keep the outlet unobstructed.

Setup and compatibility

The dial reads to 350 bar. Match the gauge, hose and regulator ratings to the cylinder system rather than treating the last scale marking as a working-pressure rating. This model supports mixtures up to 50% oxygen only within a suitably compatible, maintained system; have the complete arrangement checked for the intended gas.

Care, rinsing and storage

After each dive, rinse the gauge and hose thoroughly with fresh water. Keep the complete regulator assembled, connected to a secured dive cylinder and pressurised while washing and rinsing, with the stages, gauge and connected hoses submerged. This helps keep water out of the pressure system. Lift the equipment out and dry the cylinder connection before depressurising and disconnecting; fit the first stage’s clean, dry dust cap.

Let the equipment dry in the shade, then store it with the hose in a relaxed curve. Protect the instrument from impacts and avoid lifting the regulator or cylinder by the gauge hose. Before diving, inspect the lens, hose and fittings, check for leaks and confirm that the needle responds normally and returns to zero when fully depressurised. Have damage, internal moisture or an unreliable reading checked by an authorised technician.
