Product Details
Nitrogen online analyzer Trescon N211/Trescon S211
1. Measurement principle
The ultraviolet light emitted from the pulsating light source irradiates the colorimetric cell, and the NO in the sample solution flowing in the colorimetric cell absorbs some of the ultraviolet light. The transmitted light intensity is detected by two ultraviolet photodiodes with different detection wavelengths. After the two signals are processed internally by the instrument and compared with the calibrated values, the concentration value of NO is calculated by the instrument. The 4-beam testing method is used, and special correction functions are added to compensate for the effects of sample chromaticity, optical lens contamination, etc. Therefore, this analysis module has good long-term stability and accuracy.
2. Typical applications
Denitrification process monitoring in sewage treatment plants, continuous effluent monitoring, organic pollution level SAC monitoring (OS210), inlet and outlet monitoring
3. Advantages and Characteristics
Principle of 4 beam testing, automatic background compensation
No reagent method
Continuous
