The evaluation unit complements OZONOTEC EC. It continuously measures O₃ concentration and medium temperature in liquid and gas phases. Parameters can be adjusted to the measuring conditions and operating requirements. The IP65 / NEMA 4X stainless-steel enclosure is designed for continuous process measurements in demanding industrial environments.
 
Operation and Integration
 
 
 
Continuous LCD display of concentration, medium temperature and real-time clock.
 
 
Quick configuration using function keys and on-screen menus.
 
 
PIN-code-protected access levels and software-guided sensor calibration; air calibration is possible.
 
 
Configurable concentration alarms and integration via digital and analog outputs.
