Product description:
The TW-4722A Self-cleaning Optical Dissolved Oxygen Probe adopts advanced fluorescence lifetime technology with our proprietary high-performance fluorescent materials. Suitable for various industrial applications

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.

Features

  • Digital sensor with RS-485 output and MODBUS communication protocol support.

​

  • Optical sensor technology ensures precise dissolved oxygen (DO) monitoring without signal drift or flow restrictions.

 

  • The sensor features a self-cleaning brush that effectively prevents microbial adhesion, extending the maintenance cycle and enhancing operational reliability.

​

  • All calibration data is stored directly in the sensor, enabling on-site installation and immediate use.
