1、 Product Overview:
Zinc is an essential beneficial element for the human body. When the concentration of zinc in alkaline water exceeds 5mg/L, the water has a bitter taste and appears milky white. When the zinc content in water is less than 1mg/L, it has no effect on the growth of rice and wheat. The main sources of zinc pollution are wastewater discharged from electroplating, metallurgy, pigments, and chemical industries.
This analytical instrument is capable of long-term unmanned automatic continuous operation according to on-site settings, and is widely applicable to industrial pollution source discharge wastewater, municipal sewage treatment plant wastewater, environmental quality surface water and other occasions. According to the complexity of the on-site testing conditions, corresponding preprocessing systems can be selected to ensure the reliability of the testing process, accurate testing results, and fully meet the on-site requirements of different occasions.
2、 Technical features
*The unique design enables this product to have lower failure rates, lower maintenance requirements, lower reagent consumption, and higher cost-effectiveness and accuracy compared to similar products;
*The intelligent fault self diagnosis function makes instrument management and maintenance very convenient.
*Automatically determine the presence or absence of reagents, sound a warning sound
*Suitable for measuring pollution sources and surface water, as well as for detection in sewage treatment processes.
*It has network functionality and can achieve remote control of data through the network.
