The HI 4105 sensor can be stored assembled and ready to
use in HI 4005-45 Conditioning solution overnight or
between measurements. After overnight storage, gently pull
on the cable to compress the spring mechanism thus
permitting electrolyte to exchange from the bulk to the thin
film between the membrane and glass. Calibration is
required after doing this.
For longer term storage (over a week), disassemble the
sensor completely and rinse off the internal pH/reference
assembly, the outer body and the membrane cap. It is
advised the membrane cap be discarded to prevent pos-
sible problems associated with reuse. Cover the glass tip
with the protective shipping cap and store parts securely in
the original shipping box. When reassembling the sensor
follow section IX.
