The heavy metal detector can be widely used for rapid detection of heavy metals such as lead, cadmium, hexavalent chromium, mercury, arsenic, iron, nickel, and aluminum (optional 5 items) in rice, grains, fruits, vegetables, medicinal materials, water quality, and aquatic products. The detection items can be customized according to customer needs. Functional features:

1. This instrument analyzes and tests the reflectivity of reaction products through optoelectronic technology, and quantitatively or qualitatively analyzes the content of the analyte in the sample. 2. Android intelligent operating system, 7-inch high-sensitivity true color touch screen, more efficient and user-friendly operation interface, intuitive and simple reading. 

3. The instrument has 4G wireless networking, WiFi networking upload, and GPRS wireless remote transmission functions to quickly upload data.

4. Integrated portable rapid testing equipment, meeting the needs of on-site and mobile testing, capable of detecting all heavy metal detection items under the same software, and displaying the detection results intuitively through the same window.

 5. It has multiple food safety testing projects, an open platform, and can add or remove testing projects. 

6. Detection channels: 12 detection channels, capable of testing multiple samples simultaneously. Each sample is controlled by a program to work independently without interfering with each other. 

7. High speed thermal printer, real-time printing of detection results. Built in large capacity battery, convenient for on-site law enforcement inspections.

 8. Built in powerful database allows for direct selection of sample names, detection indicators, and inspection units on the instrument, as well as direct editing and input of sample names, detection indicators, inspection units, and other information into the sample database. 

9. The body stores tens of thousands of test results and can also be exported for storage. It is also equipped with a USB interface for easy copying of data from a USB drive.

 10. Support Wifi network, data can be uploaded on LAN and Internet, and the test results can be directly transmitted to the food safety supervision platform. Conduct regional food safety supervision and big data analysis and processing, detect the long-term and short-term dynamics of regional food safety, achieve food safety problem estimation and early warning technical parameters:

 ◆ Equipped with visible light source, can detect visible light signals, with detection values ranging from 0 to 30000.
