Hi Shaun,
The ones I have, I pinched from some electrical enclosures I was
commissioning in QLD. They are rather large and the colour of the silica can
be seen thru the bag.
I monitor them often and dry them in the oven about twice a year. Cook
then at 125 for about 30 minutes. Open the oven from time to time to let the
moisture escape.
I also use bulk silica that I put in old film cans. I drill several
small holes in the top so they can breathe. Until I started using Glad
Zip-locks, I was drying the silica about every 6 weeks. Now, it is on par
with the bags.
How long they last depends on how often you open the case / bag and how
long you keep it open. If you can find some air-tite freezer containers
(check the seals), they are a cheap solution.
Hope this helps,
Bob
