Overview
The Microprocessor-Based Ozone Detector is a dual-beam UV (254 nm) photometer for precise ozone measurement in air or oxygen. It monitors UV in measurement and reference channels, along with temperature and pressure in the cuvette, providing real-time ozone concentration on a touch screen. The system features pressure and temperature compensation, flow input for high concentrations, long-life UV light, and continuous 24-hour operation without affecting accuracy. Ozone levels can be displayed in %wt, g/Nm³, or ppmv, adjustable during operation.
Features
- Measurement features: patented technology with zero-point automatic adjustment function, dual path ultraviolet absorption principle, foreign long-life ultraviolet LED light source, continuous operation, ensuring the stability of detection concentration.
