Measurement of Ozone and pH
RANGE S200
Water Control System – WCS for Ozone
and pH
Complete set of measure and control
 Accurate measurement of Ozone concentration
 Measured parameters :
Ozone : 0-1.000 mg/L or 0-5.00 mg/L
pH : -2.00 to +16.00 pH
Temperature ; -30.00 to +140.00 °C
 Complete system plug and play
 Self-cleaning of the system
Main application areas
 Chemical and process technology
 Water and Waste water treatment
 Cooling water treatment
 Drinking water and beverage.
Advantages of the measuring system
The principle of measure is based on a potentiostatic sensor, without reagent or consumable, on a
closed-loop so reducing the costs of functioning and avoiding the loss of online water.
The whole WCS for the Chlorine dioxide included all necessary for the measure of concentration in
Chlorine dioxide: electrode potentiostatic indestructible for the measure of Chlorine Dioxyde, electrode
pH, measure and compensation in flow, room of opaque mesasure, closed-loop..
Function of automatic auto-cleaning by electrolysis allowing to dissolve the firm deposits: limestone or
fats.
Advantages of the S200 controller
Access to the menus of programming secured via password (3 user's levels).
Controller possessing numerous possibilities of piloting: 2 digital output for the control of the frequency
of functioning of dosing pump. 3 relay output potential free NO contacts, 2 analog output 0/4-20 mA, 2
separately adjustable PI..
Temperature compensation manually or by using a Pt100 or Pt1000
Calibration of the pH with automatic detection of the value of the buffer solution..
Calibration of Ozone with DPD method in single point.
