Dissolved Oxygen Analyser

Online Effluent Monitoring System

The next-generation LDO (Luminescent Dissolved Oxygen) Probe sets a new benchmark in DO measurement with its calibration-free, maintenance-light design. Thanks to a factory-performed, high-precision 3D calibration, the probe delivers unmatched stability and accuracy over its full service life — right out of the box. Designed with optical luminescence technology, this probe eliminates the need for membranes and electrolytes, dramatically reducing routine maintenance. Customizable diagnostic alerts ensure cleaning cycles are never missed, while an optimized body design delivers faster temperature response. Fully compatible with Claros, Hach’s Water Intelligence System, this sensor supports seamless data integration, remote monitoring, and enhanced process control across water and wastewater applications.
