product details

Product Model: S-8000


System Description


The S-8000 online sulfide analyzer in water is a fully automatic analyzer controlled by an embedded system, which can be applied to various water qualities such as river water, surface water, and industrial wastewater. After the sample is filtered, it is pumped into the reactor. First, a masking agent is injected to eliminate the interfering substances, and the pH value of the solution is adjusted to ensure that the solution has a suitable acidity and alkalinity. Then, according to the water sample situation, online distillation technology is selected to distill the sulfide in the water into a colorimetric cell. Then, characteristic chromogenic agents are added for color reaction with the sulfide, and the absorbance of the reactant is measured; Calculate the concentration of sulfides in the sample through the absorbance value and the correction factor stored by the monitor.
