Thermo Scientific Orion 2120XP Calcium Hardness Analyzer User Guide
The Thermo Scientific Orion calcium electrode (Cat. No. 100049) must be
used in conjunction with the Thermo Scientific Orion reference electrode
(Cat. No. 100056).
1. Unpack the calcium electrode (Cat. No. 100049) and carefully remove
it from the storage bottle that contains a high concentration calcium
salt solution. Do not touch the sensing end of the calcium electrode.
Save the bottle for future storage of the electrode.
2. Insert the calcium electrode into its port in the flow cell cap. Refer to
Figure II-9 for the location.
3. Plug the electrode cable marked "Sensing" into the top of the electrode.
Be sure to push back the black cap to verify a secure connection
between the male and female pin connection prior to tightening.
4. Tighten the screw cap connection to the cable.
Note: Do not twist the cable while tightening the connection. Twisting
may cause damage requiring premature replacement of the cable.
5. Wait at least one hour before calibrating the analyzer.
