pH/ORP Sensor

RODI's pH and ORP model P821 sensors are specially designed for convenient electrode replacement, with minimal troubleshooting and minimal maintenance. The P821 sensors are suitable for virtually all applications where high performance is required, in either in-line or submersible installations.

Sensors are available, with or without an integral differential preamplifier. The preamp converts the high impedance signal into a stable, noise-free signal, eliminating any ground loop problems.

The sensor is housed in a chemically resistant graphite-filled Ryton with Viton® O-rings. The Ryton body is used as the solution ground. The electrode tip is constructed in a.. unique Tuff Tipp® protected tip design with a Magna-Flow® peripheral ceramic reference junction, which does not require electrolyte replenishment during the life of the electrode.

The Magna-Flow® reference junction provides longer life even in harsh, dirty applications and solutions with a high solids content.
