Soil Fertiliser Heavy Metal Tester IN-ZS300

I. Brief description

The problem of soil heavy metal pollution is becoming increasingly serious and has become one of the major environmental problems facing the world today. Heavy metals in agricultural soils enter the food chain through enrichment in crops, posing a threat to the health of humans and animals, so the detection and treatment of heavy metal pollution in agricultural soils is urgent. Soil heavy metals refers to the specific gravity (relative density) greater than 5 metal elements or their compounds, these heavy metals mainly refers to mercury (Hg), cadmium (cd), lead (Pb), chromium (Cr), copper (Cu), zinc (Zn), and the class of metals arsenic (As) and so on. The mining of non-ferrous metal mines, the discharge of industrial ‘three wastes’, the accumulation of heavy metal-containing wastes, the irrigation of sewage in agricultural production, and the irrational use of agricultural chemicals may lead to the direct or indirect entry of harmful heavy metal elements into farmland soil.

Testing items

Heavy metals (lead, arsenic, chromium, cadmium, mercury, nickel, aluminium, fluorine, titanium, selenium, iron, zinc, manganese, copper) in soils, fertilisers, foodstuffs, vegetables and fruits.

Second, the detection speed

Lead, arsenic, chromium, cadmium, mercury, five tests total about 60 minutes (including soil sample pre-treatment and preparation of chemicals)

Iron, zinc, copper single test about 30 minutes, manganese test about 40 minutes (including soil samples before treatment and preparation of chemicals)

8. The instrument supports to view all historical testing records and upload all testing data.

9. Support WIFI data upload, test results can be directly transmitted to the exclusive cloud data centre, the allocation of the enterprise's exclusive cloud agricultural data centre account, the account centre can view the uploaded data of different inspectors. Platform data can be exported directly to the computer in the form of a table.

★10. The instrument is equipped with dual USB interfaces, which can export historical inspection data. It is presented in a table when viewed by computer.

★11. The online cloud agriculture data centre is also equipped with a soil testing and fertilizer application system, which is convenient for managers to account for fertilizer application standards in the absence of testing data.

★12. Equipped with mobile WeChat applet to view all historical uploaded data.

13. Sample pre-treatment experimental operation steps are built-in, the inspector does not need to control the manual, according to the instrument prompts step-by-step operation, more suitable for novice operators. In the detection step kind of built-in calibration function, no need to manually calibrate or switch calibration, to ensure the accuracy of detection.
