XS Sensor Pure Electrodes are combined pH electrodes with S7 screw head connectors. They feature a glass body and are specially designed for measuring low conductivity samples. The PURE PRO model is refillable with 3M KCl filling and suitable for samples with conductivity less than 0.2 µS, while the PURE PRO GEL model uses maintenance-free gel filling and is suitable for samples with conductivity less than 1 µS. These electrodes are resistant to pressure and temperature depending on the model.
