TracWater Dissolved Oxygen Probe Auto Cleaning
Overview
TracWater TW-4722A dissolved oxygen probe auto cleaning sensor incorporates the latest fluorescence lifetime technology. This advanced optical sensor technology ensures precise dissolved oxygen (DO) monitoring without signal drift or flow restrictions. The design eliminates the need for electrolyte solution, significantly reducing maintenance requirements. Equipped with a build-in temperature sensor, the sensor automatically performs temperature compensation to ensure measurement accuracy under varying conditions. Additionally, the self-cleaning brush effectively prevents microbial adhesion, extending the maintenance cycle and providing exceptional reliability of monitoring data.
