Thermo Scientific Orion 2117HL High Level Chloride Analyzer User Guide
The Thermo Scientific Orion chloride electrode (Cat. No. 210017)
must be used in conjunction with the Thermo Scientific Orion reference
electrode (Cat. No. 100057).
1. Unpack the chloride electrode (Cat. No. 210017) and carefully remove
the protective cap. Save the cap for future storage of the electrode.
Use the polishing strip (Cat. No. 948201) to gently polish the sensing
surface of the chloride electrode for about 30 seconds.
2. Insert the chloride electrode into its port in the flow cell cap. Refer to
Figure II-8 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.
