BF-140B type sulfide analyzer
Detection principle:

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 substances is proportional to the concentration of sulfur ions, and their absorbance is measured by spectrophotometry. After processing and calculation by a microcomputer system, the sulfide content (mg/L) is directly displayed.

Scope of application:

It can be widely used in colleges and universities, research institutes, sewage treatment plants, environmental monitoring stations, electroplating, petrochemicals, papermaking, pharmaceuticals, printing and dyeing, textiles, leather, brewing, dairy industry, electronics, municipal engineering and other industries.
