Handheld Water Heavy Metal Detector

I. Product Overview

Based on the spectrophotometric principle, the handheld heavy metal meter is 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, 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 needs no complicated pre-treatment: the user simply adds the water sample and reagent as instructed, and the concentration is read directly.

II. Measuring Principle

The meter determines heavy metals by spectrophotometry. Each metal ion undergoes a characteristic colour reaction with the chromogenic reagent in the pre-made pack (for example diphenylcarbazide for hexavalent chromium), forming 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 concentration of the metal ion, and the meter automatically applies its stored standard working curve to display the concentration directly.

III. Applications

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

IV. Key Features

1. Android operating system with an elegant interface and user-friendly operation.

2. 4.3-inch high-definition touch screen combined with a visual graphical interface that greatly improves operating efficiency.

3. High-reliability imported LED light source: no warm-up required and stable long-term performance.

4. 10 mm × 10 mm large-area photocell for high sensitivity and a low detection limit.

5. 16 GB internal memory stores more than 10,000 records; an optional Bluetooth printer prints results on site.

6. Wi-Fi and Bluetooth connectivity plus a USB port for fast batch upload of data to a PC.

7. Water-resistant housing; the measuring chamber resists the ingress of 0.5 mL of liquid.

8. Standard USB-C 5 V 2.1 A input with BC 2.1 charging protocol support: compatible with third-party phone chargers, cables and power banks, with intelligent lithium-battery charge management for continuous mains operation.
