The SensoRex Electrode pH Electrode is a glass body pH electrode with a double junction reference system. It has a pH range of 0-14 pH, a temperature range of 0-80°C, and an impedance of less than 300 MΩ. The electrode has a 12 mm diameter glass body, 1 m cable length, and BNC connector. It is compatible with most pH meters and ideal for laboratory and industrial pH measurement applications. The electrode requires storage solution and regular calibration for accurate pH readings.
