    Chlorine dioxide analyser series M 1056 C is designed for measurement and control of drinking water, waste water treatment and swimming-pool applications.
    Two basic measured parameters are chlorine doixide and temperature.
    The unit enables the construction of additional expansion modules, for measuring the pH value and the redox potential (for drinking and waste water).
    Amperometric measurement method using two electrodes and an additional third reference electrode provides a constant and continuous measurements.
    The unit consists of the following subassemblies:
    - a mechanical filter sample
    - an indicator of the flow of the sample
    - self-cleaning measuring cell
    - measurement - regulation electronics
    - cover

    The user interface for parameterization and calibration is performed via graphical LCD display. Control, regulation and control of disinfection processes are enabled by analog and digital outputs and by CANbus digital communication. The control module supports the connection of actuators - dosing pump with analog and digital inputs as well as solenoid and motorized valves - for two-point and continuous dosing. Software design of the control module contains a number of protective mechanisms against overdosing.
