Portable Colorimeter-heavy metals is a single fixed wavelength spectrophotometer, which adopt the principle of spectrophotometry to measure the parameters. In the instrument, the linear curves of the concentration of different parameters and the absorbance were established, and the concentration of the water samples was obtained through the identification of the color. It can be used to test the parameters manganese, iron, nickel, chromium, copper, zinc of water, the instrument can be customized and the user can customize the required metal parameters according to the requirements。
What are heavy metals
Heavy metals are chemical elements with molecular weight greater than 50au and metal properties. There are more than 40 kinds of these elements, but the common and toxic elements in water quality are Mercury, cadmium, lead, copper, arsenic, chromium, zinc and iron.
In rivers and lakes, heavy metals usually exist in the form of ions or salts, which increases their toxicity to the natural environment and human body. When the polluted wastewater enters the soil, groundwater or surface water, even if the concentration is very low, they can not be biodegraded. These heavy metal ions will be slowly contained in the food chain, and further transformed in one of the links. They can cause secondary pollution in the bottom of the water. The ability to accumulate in biological tissues makes them dangerous to the environment and human health.
The main pollution sources are engineering operation and electroplating production, solid waste, mining and metallurgical industry, especially nonferrous metal processing, fuel and energy and chemical industry. They all pollute the water body in a certain degree or another form, and the sewage will contain many kinds of heavy metal ions. Therefore, the composition of heavy metals in water mainly depends on the production process.
- 1.small and beautiful, easy to carry, work stable,a high performance-price ratio
2. Microcomputer system configuration, touch keyboard, LCD crystal clear display.
3. This instrument adopts the photoelectric colorimetric principle of spectrophotometry, which is simple to operate. The sample is put into the reagent for a few minutes to read, and the repeatability error is less than or equal to plus or minus 2%.
4. The instrument adopts high strength long life light source and the light source is stable.
5. The main engine is equipped with a large power battery, which can be used for quantitative measurement in the field, and can work for 6 hours continuously.
6. The calibration curves within the range of the instrument are stored in the instrument, with the protection of power failure, the calibration data will not be lost.
7. Power supply mode: 220V, 50HZ;Dimensions (mm) : 250 x 145 x 60;Weight (kg) : 1.0.
