Portable Water Heavy Metal Detector

I. Product Overview

The instrument is a portable heavy metal analyser based on spectrophotometry, designed for fast and accurate on-site determination of several specific metal ions in water. For common indicators such as hexavalent chromium, manganese, mercury, arsenic, nickel, zinc, iron and copper, optimised characteristic wavelength channels and preset standard curves are built in, together with a dedicated pre-made colour-developing reagent pack. The compact all-in-one design requires no complicated pre-treatment: the user simply adds the sample and reagent as instructed to complete the colour reaction and colorimetric measurement and read the target concentration directly.

II. Measuring Principle

Heavy metals are determined by spectrophotometry. For each metal ion a characteristic colour reaction takes place: the target metal ion in the sample reacts with the chromogenic reagent in the dedicated pre-made pack (for example diphenylcarbazide for hexavalent chromium) to form a coloured complex with strong characteristic absorption in the visible range. The built-in high-stability multi-wavelength LED source and optical sensor measure the absorbance of the coloured solution at its maximum absorption wavelength. The absorbance is proportional to the metal ion concentration, and the internal standard working curve is applied automatically to display the concentration.

III. Applications

Industrial wastewater monitoring in electroplating, electronics, metallurgy, mining, leather processing and pigment production, for routine monitoring of process wastewater, workshop outfalls and final outfalls; on-site screening and preliminary quantification of heavy metal pollution at regulated outfalls, contaminated surface water and pollution incidents for environmental regulators; and quantitative analysis of specific metals in drinking water sources, groundwater and research laboratories.
