How far can the Gravity: Analog Dissolved Oxygen Kit be submerged in water?

hi，The DO probe can be immersed for continuous measurement, but keep the signal-converter board and connectors above the waterline — and if the whole cable assembly will sit under pressure, seal the cable's top exit . The kit page doesn't publish a maximum submersion-depth number. The exact depth can be measured by using physical objects. If during the measurement process, you find that it can solve the actual problems you are facing in your project, that would be the best.
