1.Clean outside of sensors,cable and instruments
2.Check all visible o-rings for signs of wear and tear
3.Dry outside of instruments and cables
Short Term Storage
Short term - 4 weeks or less
Store in 100 % saturated air
-Air saturated with tap air -May use sponge -Do not immerse sensor in water -Periodically check to make sure it does not dry out
Conductivity only instrument
-Store field sensor in dry air -Store lab instrument in distilled or deionized water
Dry Outside of instrument before storing in air tight container.
Long term Storage
Long term - 4 week or more Storage method varies by sensor
For pH/ORP sensor- Remove the pH,ORP, or pH/ORP sensor Plug empty port Place sensor in original storage bottle filled with buffer 4 and 2 M KCI solution
For Conductivity / Temperature sensor- Field sensors can be stored dry or wet Leave in bulkhead and store according to other sensors Lab sensors should be stored in deionized or distilled water.
