Hi @bmbebout -  
@kurt_bluerobotics solved this challenge without potting via glands, as detailed in his post / doc [here](https://discuss.bluerobotics.com/t/low-cost-water-quality-sensor-packs/15505/11).

For pressure, it would likely be far easier to use a Bar30 or Bar30XT?

The Celsius fast response temperature sensor is also quite capable and easier to integrate… an upcoming update will make it potting-free!
