Model P821 Sensor TEXT SIZE: A A A    PRINT THIS PAGE   EMAIL THIS PAGE

Specially designed for convenience of electrode replacement where minimal troubleshooting and maintenance downtime are of prime importance. The P821 is suitable for virtually all applications where a high performance sensor is required, either in-line or submersible installation. The electrode features a detachable cable with an integral preamplifier which eliminates any ground loop problems. The preamp converts the high impedance signal into a stable, noise free signal.

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.
