Scuba equipment for straightforward pressure checks that help confirm tank readiness, Tyuooker Scuba Diving Air Tank Pressure Tester. Finding calm before a dive reassures both hobbyists and professionals. Is the gauge practical and robust enough for routine use?

⚡ At a Glance
  • Valve Compatibility: Fits standard DIN dive tank valve threads (G5/8)
  • Best for: Scuba divers and technicians who use DIN-valved tanks and need quick pressure checks
  • Not ideal for: Owners of tanks without DIN/G5/8 fittings, such as standard yoke setups

Designed as a straightforward pressure checker for DIN-valved tanks with a clear readout. Includes a spare O-ring and a smooth-bleeding release valve to help with basic maintenance and safe venting.


Quick, High-Range Pressure Readings - with a 400 bar / 6000 PSI gauge

Analogue gauge supports high-pressure measurement up to 400 bar (6000 PSI), suitable for high-pressure scuba and PCP applications. Luminous dial improves visibility in dim conditions.

Fast, easy-to-read pressure checks let divers confirm tank fill at a glance. Reliable high-range readings are useful for technical diving preparations and pump checks.

Secure Attachment to DIN Valves - thanks to G5/8 thread compatibility

Thread matches standard DIN G5/8 fittings used on many dive tanks, ensuring a firm connection when engaging the valve. Thread conformity reduces the chance of cross-threading when attaching for a check.

Simple screw-on fit saves time during pre-dive routines and workshop checks. Compatible connection reduces fumbling and helps ensure a proper seal for accurate readings.

Controlled Bleeding for Safer Venting - with a smooth-release bleed valve

Built-in release valve allows gradual depressurisation, designed to let air bleed away smoothly rather than in a sudden burst. The mechanism aids controlled pressure reduction after a reading.

Safer venting reduces splash and sudden noise when releasing pressure on the surface. Controlled release makes field checks less stressful and lowers the chance of rapid pressure changes.
