Nitrate Ion Management in De-nitrification Projects and Advanced Treatment with 'UV Nitrate Meter'
Measurement of nitrate and nitrite ions dissolved in water using ultraviolet-visible spectrophotometry.
The NT3100sc model is a nitrate meter that measures nitrate and nitrite ions dissolved in water using ultraviolet absorbance spectrophotometry. Total nitrogen discharge is regulated under water quality total quantity regulations. The concentration of nitrate and nitrite ions is used as an indicator for managing the nitrification process in denitrification processes and advanced treatment reaction tanks to reduce total nitrogen discharge. The NT3100sc is suitable for managing nitrate ions in such denitrification processes and advanced treatments. Features: - Measurement using ultraviolet absorption method allows for reagent-free measurement. - 215 nm ultraviolet spectrophotometer for measuring nitrate and nitrite ions dissolved in water. - Equipped with an automatic wiper cleaning function that performs cleaning automatically at set intervals. - Flexible installation according to various environments; it can be used as a submerged type where the detector is directly placed in the sample water, or as a flow type using a bypass panel (optional) to supply sample water to the measurement section of the detector.
basic information
Other Features ○ Correction wavelength: Corrects the influence of turbidity and organic matter by measuring at 230nm ○ Available in three cell lengths: 1, 2, and 5mm, allowing for the selection of detectors suited to the measurement range. ○ By combining the FILTRAX filtration sampling device with a bypass panel (flow cell), it is possible to measure by removing sludge and turbidity from reaction tanks, etc. 【Measurement Items】 NOx−N, NO3−N, NOx, NO3 (NOx−N and NO3−N can be set arbitrarily) 【Measurement Range】 Immersion type : 0.10–90.0 mg/L (cell length 1mm) NO3-N 0.05–50.0 mg/L (cell length 2mm) NO3-N 0.02–25.0 mg/L (cell length 5mm) NO3-N Flow type (bypass panel) : 0.05–50.0 mg/L (cell length 2mm) NO3-N 0.02–25.0 mg/L (cell length 5mm) NO3-N
