Choice of the
compensation type :
- linear compensation
(0.1984 mV/°C).
- compensation according to the
ultrapure water curve.
1 - compensation according to the
sulphate curve
corresponds to a pH 4.0 to
25°C).
2 - compensation according to the
ammoniac/hydrazine
(0.272 mg/l ammoniac + 20 µg/l
corresponds to a pH 9.0 to
25°C).
3 - compensation according to the
ammoniac /
hydrazine curve
ammoniac + 10 mg/l morpholine
+ 50 µg/l hydrazine corresponds
to a pH 9.6 to 25°C).
4 - compensation according to the
