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-

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.
