Waterproofing KH Director.

These are what I used:
Essdee Plastic Ink Tray 240mm x 200mm

Then the units are sat on a little egg crate.

I would like to thank you from the future .

You are welcome.

I removed these in the end. Focus on the PH probe port on the KH director, use some silicon lubricant to seal it tight and it doesn’t tend to leak.

That looks insanely frustrating to deal with come firmware update time!
