P821 Electrodes

Model P821 Sensor
Model P821 Sensor

The sensor is housed in a chemically resistant, graphite filled Ryton® with Viton® O-Rings. The graphite filled Ryton body is used as a solution ground. The electrode tip is constructed in a unique Tuff Tip® guarded tip design with a Magna-Sens® peripheral ceramic reference junction. The Magna-Sens reference junction provides longer life in harsh, dirty applications and in process solutions containing a high solid content. It is also superior in applications such as lime slurry waste treatment, paper machine headbox and pigment / dye applications. The reference does not require electrolyte replenishment during the life of the electrode.
