It is evident that environmental issues on Earth are becoming increasingly severe. Air, soil and water resources have all been contaminated to varying degrees, which deserves our close attention. Testing the heavy metal content in domestic wastewater is critical and serves as one of the key indicators for online water quality monitoring.

Why is heavy metal monitoring so important? Heavy metals are substances that are difficult to biodegrade. Through bio-magnification along the food chain, they can accumulate in large quantities and eventually enter the human body. In short, once heavy metals build up in the human body beyond safe tolerance levels, poisoning will occur. Therefore, monitoring heavy metals in water must not be overlooked.

How are heavy metal detectors applied to domestic wastewater? Most heavy metal water quality detectors manufactured by Hangzhou Modi adopt the colorimetric method. They can test various heavy metal parameters including iron, copper, nickel, thallium, cadmium, chromium and zinc. These devices are widely used for industrial wastewater, tap water and other scenarios requiring concentration detection of different forms of substances in water.

As a professional water quality detector manufacturer, Hangzhou Modi independently develops equipment for not only heavy metal detection, but also other conventional water quality parameters such as COD, ammonia nitrogen, total phosphorus and total nitrogen. We also provide instruments for key testing indicators for drinking water and medical wastewater, including biological toxicity and coliform bacteria. Besides, we support the detection of special harmful substances for water quality assessment, such as urea, sulfate, bro-mate and formaldehyde.
