INW - TempHion Instruction Manual
25
Depending on which version you have, your M and I values during calibration of the
pH channel should be in the following ranges.
Appendix C: Elements, Reference Solutions, and Related
Settings
With the exception of our Wastewater pH unit, all TempHions need to have reference
solution in the solution reservoir. (See the Maintenance section in this manual for
details on care and fi lling of the reference solution reservoir.)
The following chart shows the reference solution that should be used with various
elements. There are also specifi c settings that are set under Advanced Calibration.
These are set at the factory to match your element and need not be changed by the user.
