Go-NOGo Gas Tester — Dive Safety, Simplified
The Go-NOGo Gas Tester app is the essential companion to your Go-NOGo device, giving divers and compressed gas users real-time, reliable readings of the parameters that matter most before every dive.
Whether you're filling your own tanks, checking a fill station's output, or verifying gas quality before a dive, Go-NOGo puts reliable monitoring in the palm of your hand — connected wirelessly via Bluetooth to your Go-NOGo Analyser.
WHY GO-NOGo?
✅ CARBON MONOXIDE (CO) DETECTION Get CO readings powered by miniature gas-sensing technology, with pass/fail tolerances built around real-world calibration data — not guesswork.
✅ OXYGEN (O2) ANALYSIS Verify your gas mix with confidence. Two-phase calibration (ambient + pure O2) ensures your readings stay accurate dive after dive.
✅ TEMPERATURE, HUMIDITY See the full environmental picture, including dew point tracking, so you always know what's really in your tank.
✅ LIVE BLUETOOTH CONNECTION Fast, stable BLE pairing with your Go-NOGo Analyser — no cables, no fuss. Designed to reconnect smoothly even in real-world dive shop and boat conditions.
✅ CLEAR PASS/FAIL GUIDANCE No more second-guessing your air. Go-NOGo gives you a clear, confident readout so you know when your gas is good to go — and when it's not.
✅ BUILT FOR RELIABILITY From sensor calibration to warmup sequencing, every part of the app is engineered around reliability and repeatability, so you can trust the numbers every time.
