Chemitec Series 50 ControllerSeries 50 Multi-parameter Controller

One Controller, One Family of Sensors

Simple, Powerful, Affordable


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 configurations for (a) up to two, (b) up to four, or (c) up to eight simultaneous measurements, comprised of any combination of the parameters listed below.

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 50 Series
the whole range of Chemitec digital sensors and expandable to conventional electrodes and probes through the AD series digitizer

User Interface (HMI) Programming keypad with 5 bubble-keys with
• CAL Key for direct access to the Calibration menu
• GRAPH/USB Key for direct access to the Measure graphs and for data download to USB PENDRIVE
• MODE Key for self-recognition of sensors

Graphic TFT color LCD resolution 480x272 visible area 95x93 which allows the simultaneous display of digital measurements

Software and Functions

Internal Data Logger (64 Mbit cache) with ability 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 same parameter, the third can be set as the average of the other two.
