Introduction：
Handheld Water Heavy Metal Detector rapidly measures multiple heavy metal concentrations in water with a 6-hole digester for outdoor testing. Widely used for emergency monitoring, industrial wastewater and sewage testing....
The handheld multi-parameter heavy metal meter is developed with reference to the relevant standards and can rapidly determine several heavy metal indicators in water. Equipped with a high-definition colour LCD touch screen, the Android smart operating system and a bilingual keyboard, it is simple and user-friendly. Together with the 6-position smart digester it enables rapid heavy metal testing in the field.
Emergency monitoring, industrial wastewater, domestic sewage, sewage treatment, pharmaceutical and chemical plants, food and beverage, textile printing and dyeing, electroplating, papermaking, petroleum and metallurgy, river treatment, research institutes and universities.
