Product Details
Cadmium Online Water Quality Analyzer
>>Overview
This monitor operates autonomously under long-term unattended and continuous operation based on field configurations. It is widely applicable to
industrial pollutant discharge wastewater, industrial process
wastewater, industrial sewage treatment plants, municipal sewage
treatment plants, and similar scenarios. Depending on the
complexity of on-site testing conditions, optional preprocessing
systems can be integrated to ensure reliable testing processes, accurate results, and compliance with diverse operational demands.
>>Principle
The product utilizes the dithizone spectrophotometric method for cadmium determination. After mixing the water sample with
conditioning agents, cadmium reacts with the indicator in an acidic
environment to form a colored complex. The analyzer detects the
color intensity change, converts it into cadmium concentration
values, and outputs the results. The amount of colored complex
generated is proportional to the cadmium concentration.
