Put it in one of those sealable jars with hinges - stuff a few packets of dessicant inside to stop condensation and you're done. If you need to pass through wires score a v-shape into the seal and make sure they get squeezed tight when you close the jar. Something like http://img4.foodservicewarehouse.com/Prd/1900SQ/AmericanMetalcraft_HMJ5.jpg http://img4.foodservicewarehouse.com/Prd/1900SQ/AmericanMeta... make sure to get some extra sealing rings if you do passthroughs as it's hard to get the scoring right.
