The sensor will arrive with a protective cap that keeps the sensor membrane hydrated.
For short-term storage, put several drops of Thermo Scientific AquaSensors D.O. electrolyte (P/N
RDOK1) on the absorbent material in the protective cap and replace the cap on the sensor. This
keeps the membrane moist.
For extended storage, repeat the above short-term storage procedure every 2 to 4 weeks,
depending on the surrounding environmental conditions.
Make sure all wetted materials are compatible with process chemicals at operating temperatures
and pressures.
