Overview
The LEICI Hexavalent Chromium Reagent Pack (Model: 780800N09) is a dedicated Reagent Pack for water quality testing, suitable for the measurement of hexavalent chromium content in water. Measurement range is 0~ 5 mg/L, and can provide 100 measurements.
Features
1. Measurement range 0~ 5 mg/L to meet routine detection requirements
2. Provide 100 measurements, economical and practical
3. Designed for DGB-404F instruments with good compatibility
4. Reagent package form, easy and fast operation
Principle
The hexavalent chromium Reagent package is based on the Spectrophotometric method, spectra-trophotometry principle, through a specific chemical Reagent and hexavalent chromium in water to occur color reaction, measurement Absorbance value at a specific wavelength, calculated according to the standard Linear dispersion of hexavalent chromium concentration.
Applications
Water quality testing, environment monitoring, industrial wastewater treatment, drinking water security evaluation
Standards
GB/T 7467-1987、HJ 908-2017
Steps
1. Take an appropriate amount of water sample and add it to the Colorimetric tube
