The OPM Dissolved Oxygen Probe uses optical technology (EPA- approved RDO technology for Clean Water Act programs) to meaasure dissolved oxygen and temperature, applicable for various monitoring purposes. The DO sensor helps in monitoring Oxygen concentration in influent, effluent and treatment processes, responding quickly to oxygen and temperature changes for more accurate results.


Easy Setup And Monitoring - Flexible communication protocols connect to Your existing OPRUSS OPM controllers.
Accurate, Reliable Data - Maximum Accuracy (up to ±0.1 mg/L) Resists abrasion and photobleaching, with automated calibration that prevents long-term drift.
Easy Maintenance – Smart sensor cap stores vital information and alerts you when it’s time to replace.
24/7 Data Access – View and filter data easily using the OPM Controller module and ECOLYSER OS
