Low Range Temperature Compensation
Select the type of low range (0 to 100C [32 to 212F]) temperature compensation
required:
Linear – Linear temperature compensation based on a manually entered
temperature coefficient (see Appendix A1) – see
page 26.
Example
• Non-standard applications.
UPW* – Temperature compensation based on the temperature coefficient of pure
water. Source data is based on International Standard IEC 60746-3.
Also enables manual entry of a temperature coefficient (see
frame on page 26) for applications where pure water contains an unknown
impurity; in which case the temperature coefficient must be calculated –
see Appendix A1.1.
Acid** – Temperature compensation based on the temperature coefficient of pure
water containing trace acids.
Examples
• Cation exchanger in-bed and outlet applications.
• Degassed cation/conductivity applications.
NaOH*** – Temperature compensation based on the temperature coefficient of pure
water containing trace caustic.
Example
• Inferred pH in caustic-dosed waters applications.
NaCl* – Temperature compensation based on the temperature coefficient of pure
water containing trace salts.
Examples
• General monitoring applications.
• Mixed-bed exchanger applications.
• Final polisher effluent applications.
• Cation exchanger inlet applications.
• Anion exchanger in-bed and outlet applications.
• Reverse osmosis applications.
NH3 – Temperature compensation based on the temperature coefficient of pure
**
water containing trace ammonia.
Examples
• Ammonia-treated make-up and boiler feed water applications.
• Condenser sampling applications.
• Hot well sampling applications.
• Before-cation column applications.
• Inferred pH in ammonia-dosed waters applications.
* Applicable only on conductivities up to 10S cm
** Applicable only on conductivities up to 25S cm
*** Applicable only on conductivities up to 100S cm
