Overview
Sulfide analyzer HG-SZ-140S
Product Details
Product Description, Technical Parameters, and Configuration
Detection principle:
The HG-SZ-140S water quality sulfide analyzer is developed and designed based on the authoritative certification method GB/T16489-96 "Determination of Sulfides in Water Quality - Methylene Blue Spectrophotometer" standard. In an acidic solution containing high-speed iron ions, the color developer directly reacts with sulfur ions to generate colored substances. The color depth of the colored substance is proportional to the concentration of sulfur ions. The absorbance of the sample at a specific light source wavelength is detected by spectrophotometry, and after automatic data processing by a microcomputer, the sulfide concentration value of the sample is directly displayed in mg/L.
