MC measuring inputs
All measuring inputs consist of an input for temperature measurement via Pt100 and a second input for the measurement of a further water parameter.
On some measuring inputs, this input will measure a number of different parameters.
Measuring inputs (depending on version)
Number of measuring inputs up to 4
Free chlorine
Amperometric 3-electrode measur-
ing cell with potentiostat (DMZ3.1)
mg/l 0 – 15 (dependant on the measuring cell transconductance)
CS120 excess chlorine measuring cell mg/l 0 – 10 (dependant on the measuring cell transconductance)
Diaphragm-covered measuring cell mg/l 0 – 10 (dependant on the measuring cell)
Chlorine dioxide
Amperometric 3-electrode measur-
ing cell with potentiostat (DMZ3.1)
mg/l 0 – 15 (dependant on the measuring cell transconductance)
CS120 excess chlorine measuring cell mg/l 0 – 10 (dependant on the measuring cell transconductance)
Diaphragm-covered measuring cell mg/l 0 – 2 (dependant on the measuring cell)
Total chlorine Diaphragm-covered measuring cell mg/l 0 – 10 (dependant on the measuring cell)
pH value pH single-rod measuring cell pH 0 – 14 (dependant on the single-rod measuring chain)
Redox value Redox single-rod measuring cell mV 0 – 1000 (dependant on the single-rod measuring chain)
