SMART WG-2 pH + ORP + °C
|
pH value controller and redox value controller for pH-redox-°C measurement for wall mounting.
This pH process measuring and control device measures pH, redox and temperature. This industrial controller is used in industrial measurement and control technology, in the food industry, in the chemical industry, in the pharmaceutical sector, in fresh and waste water technology, in pool measurement technology and in electroplating technology.
The pH process controller comes in a splash-proof wall-mounted housing 120 x 122 mm and is designed for mounting on the wall or on a panel.
2 analog outputs 0 (4)...20 mA, 2 control outputs (relays), which can be configured as limit values, as pulse length controllers, as pulse frequency controllers and as alarm outputs, provide the connection for further signal processing.
When developing the configuration level, particular attention was paid to user-friendliness.
