My DIY 0.005% Resistance Standard. Is there a Point of Measuring with 34465A?

The box will shortly be filled with silica gel desiccant and sealed with silicone gasket material.

You may already know this, but for those who don't, you can't use just any RTV silicone caulking.  There is a grade just for electrical things that doesn't cause corrosion.

Absolutely! The stuff used for aquariums to bond glass sheets together does not release acetic acid as it cures and is the right stuff for this application.

Be mindful of the actual silicone though. Ive gotten aquarium silicone that is acetic acid cure. I guess a bit of acetic acid is not so harmful to the fish if the PH is managed, compared to methanol or amines. But the acetic acid will still cause problems for electronics.

RTV 3145 is a good material for sealing but no cheap.
