Touch series significant features overview
- Touch screen controllers with user friendly programming interface;
- Standard Ethernet (LAN) connection, Modbus TCP + data logger + USB port; Graphic charts and data logger download;
- Auxiliary functions drive remote equipment either via a relay output or by means of a timer programming, allowing the user to choose the exact time, date, week these equipment must operate and for what time duration making Touch series a perfect tool for automated systems; the functions can also be renamed using the keyboard;
- PH measurements can be changed to RX just changing the parameter during programming and using RX electrode;
- Chlorine measurements features 4 chlorine ranges suitable for Membrane type chlorine sensors 0-2 ppm, 20 ppm, 0-200 ppm and also for open type chlorine cell range 0-10 ppm;
- Conductivity measurements are in micro Siemens features K factor ranges (Cell Constant) selectable by the operator: ranges K1 20.000 µS; K 5 up to 2.000 µS; K 0,1 up to 200.000 µS; K10 up to 200 µS;
- PPM measurements suitable for Membrane type sensors for various ranges: 2 ppm, 20 ppm, 200 ppm, 2000 ppm, 20000 ppm and 200000 ppm. Measurements: Dissolved Oxygen; Hydrogen Peroxide; Bromine; Chlorine Dioxide; Peracetic acid; Chlorites; Absence of Chlorine.
BENEFITS: The above feature allow dealers to stock one type for all controller thus reducing stock value or saving time and money when placing orders to manufacturer. Touch screen is widely used by all, a friendly user menu programming, almost self-explanatory and the elegant wide display allows easy vision. Different models are available each featuring different functions to ensure a high level of measurement accuracy and safety.
WI-FI remote control by smartphone or tablets: it allows operator to connect via WIFI and change programming and settings. Unit will send an email in case of alarm level or overdosing functions. Graphic charts Visualization.
GSM external module for receiving sms in case of alarm level or overdosing settings.

Remote control features
Both TOUCH and CTRL series are suitable for remote control by RS485 expansion board with Modbus protocol using FWT® software.
A USB port allows to download all operations data events on a pen drive.
ETHERNET connection: it allows operator to connect to the unit via PC and change programming and settings using FWT® CTRL software. Unit will signal once reaching alarm level or overdosing settings.

WIFI connection controls TOUCH series operations via Internet by PC, Mac, Tablets and Smartphone. A self-explanatory program allows the operator to change settings and programming. Unit will send an email once reaching alarm levels, overdosing point or Max dosing pump time out.
In alternative it is also available a GSM module for receiving sms in case of alarm level or overdosing settings.
