The NT200 analyzer is a UV spectrometer tuned on the wavelength nitrates absorb at. It does perform a selective measurement taking into account the turbidity and the presence of interfering species if necessary.
The UV source of the analyzer is a xenon lamp which is ensured a very low energy consumption and a long life time (more than two years if a measurement is made every 15 minutes) thanks to specially designed feeding mode. Many successive flashes are started for each analysis and the mean of all the results is calculated by the analyzer in order to ensure the perfect reproducibility of the measurements. Any electronic disturbance likely to affect the result of the analysis is detected by the analyzer and sets a default off.
The measurement is expressed in mg/L NO3- or in mg/L of nitrogen. The measurement unit is made by the user himself on the keyboard of the analyzer. The analyzer is calibrated at the factory and therefore requires no re-calibration. The use of UV spectrometry ensure the reliability of any measurement over long-termed periods.
The measurement results can be remotely transmitted using a 4 – 20 mA output. The range of variation can also be set by the user.
Advantages:
- Online nitrate monitoring: 0 – 250 mg/L NO3 (0 – 50 mg/L N-NO3); 0 – 1000 mg/L NO3 (0 – 200 mg/L N-NO3)
- Quick results: Nitrate measurement in 20 seconds with no reagent needed.
- Long-term reliability of the measurement: UV nitrate measurement technology; Automated cleaning system and zero adjustment
- Functional measurement of dirty: Large section hoses: limited risk of clogging; Optical turbidity compensation.
