The new model launched by Shandong Yuntang Intelligent TechnologyPortable Soil Heavy Metal AnalyzerThe instrument measures heavy metals (lead, arsenic, chromium, cadmium, mercury, iron, zinc, manganese, copper) in soil, fertilizers, food, vegetables, and fruits. Strong scalability, this instrument can not only detect heavy metals but also expand the testing of nutrients in soil, fertilizers, and plants, making it versatile.

Heavy metals are particularly prominent in soil inorganic pollutants, mainly due to their inability to be decomposed by soil microorganisms and their tendency to accumulate and transform into more toxic methyl compounds. Some even accumulate in the human body at harmful concentrations through the food chain, seriously endangering human health.

Instrument function:
1. The Android intelligent operating system adopts more efficient and user-friendly operation. The instrument has Ethernet connection, WiFi network upload, 4G wireless remote transmission function, and can quickly upload data.
2. Adopting high-precision filter technology for independent analysis method, the colorimetric groove adopts a standard 1cm colorimetric dish without mechanical displacement or wear, and the optical path testing positioning is accurate to ensure that the detection results are better than the national standard requirements.

3. The instrument has 12 detection channels, which can detect and compare multiple samples at once, reducing detection costs.
4. The instrument is equipped with a new generation high-speed thermal printer, which can automatically print inspection reports and QR codes upon completion of testing.
5. Each channel is equipped with a four wavelength cold light source, which can expand more detection elements. All light sources achieve constant current and voltage stabilization, ensuring wavelength stability, good reproducibility, and high accuracy.
6. Display mode: 7-inch LCD touch screen display, user-friendly Chinese operation interface, intuitive and simple reading. 7. AC/DC dual-use, can be connected to car power supply, equipped with a 6-hour high-capacity rechargeable lithium battery, convenient for outdoor mobile testing.
8. The instrument is equipped with a regulatory platform. The detection data can be uploaded to the regulatory platform for data monitoring and statistics.
9. The main control chip adopts ARM Cortex-A7, RK3288/4-core processor, with a main frequency of 1.88GHz, faster operation speed and stronger stability.
