product overview

The pollution of water resources by heavy metals is gradually becoming a serious problem facing the world. The World Health Organization has published safety reference values for heavy metal content in water in various fields at the ppb level; The Chinese government has also introduced many relevant standards in terms of environmental safety, such as the "GB 5749-2006 Sanitary Standards for Drinking Water" and the "CJ/T 206-2005 Urban Water Supply Quality Standards", which stipulate that the heavy metal content in safe drinking water is as low as ppb level.

The existing optical detection methods have high operating costs and low detection sensitivity (ppm); However, atomic absorption spectroscopy instruments are expensive and require complex sample preparation, making them unsuitable for on-site or emergency testing.

NanoTek 2000 portable heavy metal analyzer for water quality is a patented product jointly launched by Shenzhen Langshi Scientific Instrument Co., Ltd., Nanjing University and the Chinese Academy of Sciences. This instrument introduces a new design concept in electrochemical analysis. The portable heavy metal analyzer for water quality adopts a uniquely designed reaction chamber, which greatly improves the accuracy and sensitivity of detection, while enhancing the simplicity of instrument use.
