Wastewater from industries such as pharmaceuticals, biopharmaceuticals, and food brewing often contains trace amounts of heavy metals, which come from catalyst residues, equipment corrosion, or raw material impurities. Although the concentration is low, strict monitoring is still required due to its biological toxicity. The water quality heavy metal detector is suitable for low concentration and high compliance scenarios due to its high sensitivity, multi-element coverage, and easy operation.

The instrument can accurately determine the key indicators such as lead (limit value 0.5mg/L), cadmium (0.05mg/L), mercury (0.005mg/L), arsenic (0.5mg/L), hexavalent chromium (0.5mg/L) and so on in wastewater, which meets the requirements of the Discharge Standard of Water Pollutants for Fermented Alcohol and Baijiu Industry (GB 27631-2011) and the Discharge Standard of Water Pollutants for Chemical Synthetic Pharmaceutical Industry (GB 21904-2008). The use of 30mm or 50mm colorimetric dishes can improve the detection accuracy of low concentration samples, with indication errors controlled within ± 5%.

At a certain antibiotic production enterprise, laboratory technicians conduct daily sampling and testing of workshop drainage outlets, with a focus on monitoring the content of nickel and cobalt (from the synthesis process of vitamin B12). The instrument has a built-in standard curve, and the operator only needs to select the "total nickel" item, and the system automatically calls the method parameters. The test results are synchronized and uploaded to the enterprise environmental management platform, and monthly compliance reports are generated for future reference.

The device is equipped with a 6-speed optional lithium battery, suitable for use in explosion-proof areas or workshops without sockets; The 8-inch touch screen remains clear and visible under strong light; The Chinese interface lowers the operational threshold. The teaching video module provides a detailed demonstration of the entire process from sampling to printing, allowing new employees to operate independently in half an hour. 8 million sets of data storage ensure that testing records for more than three years do not need to be cleaned, meeting audit traceability requirements.

This instrument does not rely on large infrastructure and can complete the entire process of testing by a single person. It is particularly suitable for small and medium-sized enterprises to establish independent monitoring capabilities and help promote green production and sustainable development.
