Product Specification

PH Shallow Water Sensor with Integrated Electronic Device
Glass and reference electrode in one housing - for depths of up to 1200 m

The pH-combined shallow water sensor with integrated electronic device has been developed above all for interfacing with existing CTD probe systems. The sensor consists of a pressure balanced glass-electrode and a reference electrode (Ag/AgCl) in a plastic rod. It is equipped with a ceramic diaphragm containing a high number of pores. The electrolyte is a KCl containing gel without silver ions to allow also measurements in H2S and sulphide containing samples.

The pH shallow water sensor is equipped with a titanium housing including the electronic device, with a plastics protection cage and a BH 4 M SUBCONN titanium connector. On own risk the protection cage could be screwed off. The sensor has to be calibrated by the customer itself (calibration on request). All electrodes are delivered with wetting cap containing pH 4 buffer/KCl and covering the measuring end.
