iPH-306 Online PH Sensor

For environmental monitoring of water quality, acid / base / salt solution, a chemical reaction process, industrial processes, it is possible to meet the requirements of most industrial applications online pH measurement. Signal output: RS-485 (Modbus / RTU protocol). Easy connection to a third-party equipment PLC, DCS, industrial control computer, universal controller, paperless recording instruments and a touch panel. Dual high impedance differential amplifier, interference is strong, fast response. Patent pH probe, an internal reference at a pressure of at least 100KPa (1Bar), the extremely slow bleed fluid from the micropores than the salt bridge, the forward bleeding continued for 20 months. Such reference system is very stable, doubled to extend electrode life than ordinary industrial electrodes. Easy installation:Submerged installation . IP68 protection class.
