Stationary pH-redox Controller Smart LC-pH
Stationary pH-Redox controller for professional applications / 
measuring range of 0…14 pH, and from -1800…+1800 mV / 
2 potential-free relay contact / very precise / simple operation

Our stationary pH redox controller Smart LC-pH is an all-round pH redox controller and applicable for stationary operations. Our stationary pH redox controller is used by professionals and specialists in various application fields for research. Our stationary pH redox controller is equipped with different configurable outputs, three potential-free relay contacts that can be arbitrary allocated at 250 V AC and 8 A ohm resistive load, as threshold switch (GW), for monitoring (Alarm), as proportional pulse frequency controller (PRF) or as a proportional pulse length controller (PRI). As a temperature sensor, a PT100 2-conductor can be connected to the pH-Redox controller. Our stationary pH-Redox controller is furthermore equipped with internal data storage that can store up to 4900 pH- or redox measuring values including date and time and can later be transferred to a computer or printer. For further information about the stationary pH-redox controller Smart LC-pH, please read the following technical data or call our Hotline: +44 (0)2380 987030.
