Our O2ptima Calibration Caps allow divers to calibrate sensors without having to repeatedly flush the loop, thus wasting precious gas. This minimizes the amount of oxygen required for calibration meaning more oxygen available for the dive, which is especially important when carrying small tanks.
The black inlet cap has a standard BC Quick Release fitting to plug in the manual addition oxygen hose. The red exhaust cap is fitted with a mushroom valve and prevents over pressurizing the canister.
