Complete and flexible system for a wide range of applications in water treatment with easy to use software and automatic recognition of sensors: available in three configurations, up to two (2), four (4) and eight (8) simultaneous measurements, freely selectable.

Equipped with two RS485 serial ports: one (1) for sensors with RS485 digital interface and MODBUS RTU protocol and one (1) opto-isolated for the connection with the communication devices (Setup Computer, Remote Control Terminals etc.) of the local networks.

Incorporates a Real Time Clock (clock with date) which allows the software to archive the data chronologically to the flash memories also used for storing LOG files of the events.

Connectable to the whole range of Chemitec digital sensors and expandable to the traditional electrodes/probes through digitizers AD Series

    Software & Functions
    Internal Data Logger (flash 64 Mbit) with possibility to store up to 250.000 records and to display stored data in tabular and graphic form. Data download to USB PENDRIVE or through RS485 and C_NET dedicated SW.

    Programmable Analog Outputs for repeating the measurements, PID control and temperature; with the first and the second set on the measurement of the same parameter, the third can be set as the average of the other two.

    Digital Output Relays to adjust the Set Points for the measures, the alarm for instrument anomaly, the probe washing or the Set Point for temperature.

    Analog Input for perturbative functions or engineered display of additional measuring.

    Digital Input for disabling of dosage.
