Compact Tank Pressure Gauge Din
The Compact DIN Tank Pressure Gauge lets you check a cylinder’s contents at the surface without assembling a complete regulator set. It is useful when checking stored cylinders or deciding which bottles need filling before a dive trip.
Features and benefits
- Direct DIN connection. The tester attaches to a compatible DIN cylinder valve, keeping a surface pressure check compact and self-contained.
- Two pressure scales. Bar and psi markings let you read the pressure in the unit used by your cylinder records or filling routine.
- Luminous 48 mm face. The dial provides a readable pressure reference and remains luminous after exposure to light.
- Easy to pack. The compact body is convenient to keep in a protected space in your equipment bag for pre-trip checks.
Setup and compatibility
Use this tester for surface checks only. Confirm the valve connection and permitted working pressure before use; the 400 bar/6000 psi scale is not a statement of the tester’s working-pressure limit.
Follow the tester’s operating instructions: secure the cylinder, make the connection with its valve closed, and pressurise slowly with the face directed away from people. Close the cylinder valve and release all trapped pressure using the prescribed procedure before removing the tester. A contents check does not verify breathing-gas composition.
Care, rinsing and storage
After use, wipe the outside with a soft cloth dampened with fresh water, keeping the inlet and valve connection dry. Do not submerge this surface pressure tester or let water enter its pressure passage. Allow it to dry in the shade before putting it away in a protective case.
Inspect the connection, seal and viewing window before each use. Check that the pointer returns to zero when the tester is completely depressurised. Stop using it if it leaks, sticks, shows internal moisture or has been damaged, and have it checked by a qualified technician.
