YZ-SU51 high-precision soil heavy metal detector

Product Introduction

Based on the fact that heavy metals in farmland soil accumulate in crops and enter the food chain, posing a threat to human and animal health, it is urgent to detect and control heavy metal pollution in farmland soil. Soil heavy metals refer to metal elements or their compounds with a specific gravity (relative density) greater than 5, mainly including mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr), copper (Cu), zinc (Zn), and metalloid arsenic (As). The mining of non-ferrous metal mines, the discharge of industrial "three wastes", the accumulation of heavy metal containing waste, sewage irrigation in agricultural production, and the unreasonable use of agricultural chemicals may all lead to the direct or indirect entry of harmful heavy metal elements into farmland soil. The high-precision soil heavy metal detector can detect heavy metals (lead, arsenic, chromium, cadmium, mercury, nickel, aluminum, fluorine, titanium, selenium, molybdenum, iron, zinc, manganese, copper) in soil, fertilizers, food, vegetables, and fruits.

Detection Time

8.The instrument supports viewing all historical detection records and uploading all detection data.

9.Supports WIFI data upload, and the test results can be directly transmitted to a dedicated cloud data center. An enterprise specific cloud agriculture data center account is assigned, which can view the uploaded data of different testing personnel. Platform data can be directly exported to a computer in tabular form.

10.The instrument is equipped with dual USB interfaces, which can export historical detection data. When viewed on a computer, it is presented in a table format.

11. The online cloud agriculture data center is also equipped with a soil testing and formula fertilization system, which facilitates management personnel to calculate fertilization standards without testing data.

12.Equipped with a mobile WeChat mini program to view all historical data.

13.The sample pre-treatment experiment operation steps are all built-in, and the testing personnel do not need to refer to the instruction manual. They can operate step by step according to the instrument prompts, which is more suitable for novice operators. There is a built-in calibration function in the testing steps, which does not require manual calibration or on/off calibration to ensure testing accuracy.

14.Built in independent sample processing operation video, click on the instrument main interface to watch, one-on-one guidance teaching.

15.Dual use AC/DC power supply, the instrument is equipped with a large capacity lithium battery, which can work continuously for 10 hours when fully charged.

16.External voltage display panel, which can directly display real-time detection voltage, ensuring stable detection environment and ensuring detection accuracy; And it has a power-off protection function, which can automatically store data in case of sudden power outage to prevent data loss.

17.Four specialized experimental light sources (red, blue, green, orange) with stable wavelengths, a lifespan of up to 100000 hours, good reproducibility, and high accuracy.

18.4-channel fixed colorimetric cell (solid-state module), integrated with the instrument, without mechanical displacement or wear, avoiding mechanical displacement, ensuring the accuracy of detection results, and equipped with a reminder function for each channel's detection completion.

19.The colorimetric tank is built into a sunken enclosed cabin, with a circular light shielding plate with a diameter of 15.7cm covering the entire area to prevent light leakage during the experiment and ensure accurate detection results.

20.High strength PVC engineering plastic carrying case design, sturdy and durable, easy to carry, and suitable for outdoor flow testing.
