The 70 has been developed by Chemitec for industrial applications and is especially suited to the drinking water and swimming pool water treatment sectors.

It is equipped with all the analogic and digital outputs to be able to control the pump and valve actuators also in a proportional mode (PID and PWM mode). The intuitive 70 series is equipped with a user-friendly interface and touch screen for quick and simple control.

Up to eight parameters can be measured, displayed on the main screen and stored in the internal data logger, which can be consulted on the screen via graphic mode or downloaded via internal Wi-Fi mode. There are four mA outputs with PID control for the proportional control of the dosing pumps, as well as seven relays, five with 230Vac direct drive pumps.

The 70 series also includes the standard Modbus RS485 serial. The large seven “RGB 800x480 color display allows you to view all the parameters on a single screen. The exceptionally easy-to-use interface allows the calibration of the measurements and the dosage settings to be performed in just a few steps. In the absence of flow, the dedicated digital input blocks all dosages and a signal is sent via alarm relay. All information can be displayed on a smartphone or PC thanks to the integrated Wi-Fi module.
