Compact pH-Controller Type 8205
The pH-controller compactly combines a pH-sensor and a PID-controller with display in a splash-proof plastic NEMA 4 enclosure. The sensor component consists of a replaceable combination pH-electrode, screwed into the sensor housing. The measured signal is conveyed to the controller via a coax plug. The Pt1000 for automatic temperature compensation is a standard feature in the sensor housing.

The controller component converts the measured signal and displays the actual value and computes the command signals.

Compact version for fitting Types S020 and 1500 / 1501.

Remote pH-Controller Type 8205
The pH-transmission system combines a pH-sensor Type 8200 and a remote pH-controller Type 8205 with display. The 8205 remote PID-controller is available in a panel-mounted version and in a wall-mounted plastic NEMA 4 enclosure.

pH-Sensor Type 8200
A wide range of pH-sensors with different characterized electrodes and process connections offers a large range of mounting and pH-measurements.

The Pt1000 for automatic temperature compensation is available as an optional feature in the pH-sensor housing.

Remote indication with a separated controller module for wall or panel mounting is connected over coaxial cable with pH-sensor Type 8200 for distances up to 15 feet (longer distances up to 1500 feet on request).

Sensor Type 8200 is used for mounting on different fitting types like S020, 1500 / 1501, TriClamp ® or sanitary versions.
