New NT3 Series provides more accurate and reliable measurement
The new NT3 Series Sensors from Hach bring greater accuracy, simplified maintenance, and dual parameter capability for nitrate and nitrite to your monitoring toolbox. Backed by a legacy of reagent-free UV absorbance technology expertise, Hach’s NT3100sc UV Nitrate and NT3200sc UV Nitrate and Nitrite Sensors are equipped to meet your unique application needs.
Benefits:
- Save time and money: two applications in one
- Peace of mind thanks to improved accuracy and lower limit of detection at 0.02 mg/L NO₃-N*
- Reduced maintenance cost with Hach’s proven wiper technology for automatic cleaning and prolonged 2-years’ service intervals
- Compliance safety with reliable online results in real-time
- Highest Flexibility thanks to compatible hardware options with SC4500, SC1000 or SC200 controller
Intended use
The NT3100sc and NT3200sc probes are intended for use by water treatment professionals to make sure that there is a consistently low level of nitrate and nitrite in the municipal sewage at treatment plants, surface water, untreated water and treated drinking water. Low nitrate and nitrite levels prevent water toxicity exposure and/or make sure of regulatory compliance.
Theory of operation
Nitrate dissolved in water absorbs UV light with wavelengths below 250 nm. The nitrate and nitrite absorption of UV light makes it possible to photometrically determine the nitrate and nitrite dissolved without reagents. The sensor is put directly in the medium. The color of the medium does not influence the measurement because the measuring principle is based on the analysis of invisible UV light.
