AG-SELECT controllers are high-tech microprocessor-based devices to measure and control one electrochemical parameter among pH value, RX (Redox potential), Chlorine concentration and another electrochemical parameter. These controllers are highly flexible and can be configured to measure any of the above-mentioned parameters, by means of one of our wide range of sensors. There is no need to worry about power supply settings, since they are automatically detected by controller at power-up • Plastic casing for panel mounting • Microprocessor technology • Backlight alphanumerical LCD display • Two points probe calibration • Automatic/Manual temperature compensation • 2 independent adjustable setpoints • Hysteresis setting • Delay activation function • 2 adjustable TTL outputs • 2 adjustable 4÷20mA outputs • Galvanically isolated electronics • Removable connecting terminal boards • Wide range of power supply options available: from 90 to 260Vac and from 1 to 36Vdc for RCD and BCD 24 Vac or 230 Vca.


Upon request, Etatron provides a remote monitoring software for AG SELECT (DIN, RCD, BCD models excluded). Aside it has to be purchased connection wires PC/Controller.



Serial output for computer connection • Daily/Weekly timer for programmed auxiliary dosing, for flocculant or sensors cleaning cycle • Recorder measuring parameter over MMC card (not included). Simultaneous control of 1 measuring parameter.
