Dissolved Oxygen Sensor

Overview

Featuring ABB's EZLink technology, users of ABB’s DO system benefit from plug-and-play connectivity, automatic sensor recognition / set-up, predictive diagnostics and enhanced measurement accuracy.

Users benefit from:

  – No calibration required 

  – No sensor drift 

  – Fast speed of response 

  – Minimized installation and maintenance time

  – Resistant to abrasion and photobleaching

  – No loss of performance, 2 year sensor cap life
