Overview
HI767 Nitrite ULR Tintometer is an experimental instrument for rapid and accurate measurement of nitrite content in water samples. Based on the chemical reaction between nitrite and Reagent, the concentration of nitrite in water samples is determined by measurement of Optical inspection characteristics of color-developing compounds. Widely used in environment protection, drinking water safety and other fields.
Features
1. LED Illuminants have better performance and higher luminous efficiency than traditional tungsten lamps and other Illuminants, and can use less energy to provide stable Illuminants. LED can ignore the generated heat, because higher heat will affect the Stability of electronic products.
2. HANNA's well-designed CAL CheckTM function allows meter performance verification and calibration using NIST traceability standards; the CAL CheckTM NIST Linear dispersion calibration set is used to simulate specific Absorbance values for each wavelength to verify the accuracy of subsequent readings.
Principle
Based on the chemical reaction that occurs between the nitrite and the Reagent, the concentration of the nitrite in the water sample is determined by measurement of the Optical inspection properties (e.g. Absorbance or Color intensity) of this color-developing compound.
Applications
Environment protection, drinking water safety
Standards
EPA 354.1 Diazo method ferrous sulfate method
Steps
1. Sample Handling with Optional Reagent HI764-25.
2. Use calibration group HI764-11 for instrument calibration.
3. Put the processed sample into Tintometer measurement.
4. Read and record nitrite concentration data.
Notice
Nitrite is a toxic and harmful substance during nitrification and needs to be controlled at an undetectable concentration level.
• Mature Biological Filters should ensure low levels of nitrite.
• The instrument automatically shuts down after two minutes of inoperation to save energy.
• Verify and calibrate performance using NIST traceability standards to ensure measurement accuracy.
