1、 Product Overview:
Nickel salts can easily cause allergic dermatitis. Some reports suggest that nickel is carcinogenic and has significant toxic effects on aquatic organisms. The concentration of nickel in clean surface water is very low, around 1ug/L. The main industrial pollution sources of nickel are wastewater and waste residue discharged from mining, smelting, electroplating and other 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、 Instrument 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;
*Advanced digestion system reduces system maintenance, accelerates reaction process, and enables the tested substance in the sample to react more fully and thoroughly;
*The intelligent fault self diagnosis function makes instrument management and maintenance very convenient.
*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.
