Overview

The HI767 Nitrite LR Tintometer is a HANNA brand photometer specifically designed to detect nitrite content in water samples. The instrument is based on the chemical reaction between nitrite and Reagent. Optical inspection properties of color-developing compounds are measured to determine nitrite concentration. It is widely used in areas such as environment protection and drinking water safety to provide fast and accurate measurements.

Features

1. LED Illuminant is used, which has higher performance and luminous efficiency than traditional tungsten lamps. Energy consumption is small and Illuminant is stable, and the influence of its own heat on electronic stability can be ignored. 2. Capable of CAL CheckTM, allowing performance verification and calibrating using NIST traceability standards, simulating specific Absorbance values through NIST Linear dispersion calibration sets to verify reading accuracy.

Principle

The HI767 Nitrite LR Tintometer is based on the chemical reaction between the nitrite and the Reagent. Optical inspection properties (such as Absorbance or Color intensity) of the resulting color-developing compound are measured to determine the concentration of nitrite in the water sample. Measuring method uses the EPA 354.1 diazo ferrous sulfate method.

Applications

Environment protection, drinking water safety

Standards

EPA 354.1

Steps

1. Sample Handling with Optional Reagent HI767-25. 2. Use calibration group HI767-11 to calibrate the instrument. 3. Put the processed sample into the Tintometer for measurement. 4. Read and record nitrite concentration data.

Notice

• The instrument will automatically shut down after two minutes of no operation, and pay attention to the operation interval when using it. • Measurement accuracy of +/- 10 ppb +/- 4% of reading to be used within specification to ensure accuracy. • Before use, the performance verification should be carried out through the CAL CheckTM function to ensure that the instrument is in normal condition.
