Pyxis FR-300 self-brushing system

Pyxis FR-300 Self-Brushing System

Magnetic coupling motorized brush flow assembly that provides an inline mechanical cleaning of the ST-765SS Series

This unique device enhances the convective mass transport of the oxidizer analyte to the sensor surface eliminating the need for precision flow control commonly required for other amperometric sensors on the market. The FR-300-PLUS also provides supplemental deactivation protection of the bare gold electrode for long life, stability, and accuracy.


The FR-300-PLUS comes equipped on all IK-765-B Series and SFA-765-TCL-B series panels from Pyxis Lab. Over time, the internal brush itself may require replacement. Part number details on the replacement brush assembly can be found in the manual download.
