HM-ZSD soil heavy metal rapid analyzer Introduction: The problem of soil heavy metal pollution is becoming increasingly serious, causing a large accumulation of heavy metals such as cadmium, copper, arsenic, chromium, mercury, iron, zinc, manganese, copper, aluminum, etc. in the soil cultivation layer, which has become one of the main environmental problems currently faced. Heavy metals in soil accumulate in crops and enter the food chain, posing a serious threat to human and animal health. The mining of non-ferrous metal mines, the discharge of industrial "three wastes", the accumulation of heavy metal 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 the soil, resulting in serious excessive heavy metal content in soil, crops, fruits and vegetables, water quality, aquatic products, and other heavy metals. However, the current heavy metal determination methods have slow measurement speed, cumbersome steps, and expensive instruments. Based on this situation, we have developed a rapid determination method for heavy metals. Features: 1. The Android intelligent operating system adopts ARM Cortex-A7 as the main control chip, RK3288/4 core processor, with a main frequency of 1.88GHz, faster operation speed, and stronger stability. 2. Adopting a precision rotating colorimetric cell design, the consistency of the light source is more precise, ensuring detection accuracy. 3. 12 rotating detection channels can quickly detect 12 samples at once, greatly improving detection efficiency and reducing detection costs. 4. Adopting high-precision filter technology and independent patent analysis method (patent number: ZL 2018 2 1777724.7), with authoritative certification. 5. Built in calibration function during the detection process, intelligent constant current and voltage regulation, and automatic light intensity calibration ensure detection accuracy. 6. The instrument comes standard with WiFi wireless upload, 4G network transmission, GPRS wireless remote transmission, and fast data upload. 7. Equipped with a cloud platform, the instrument can selectively or in bulk upload detection data wirelessly after being connected to the wireless network, facilitating long-term data management and visual analysis by users. 8. The instrument is equipped with both USB and Ethernet interfaces, built-in large capacity memory, and can be copied with a USB drive at any time. 9. You can log in to the cloud platform anytime with your mobile phone and view historical data online 10. 4 wavelength professional testing cold light source (red, blue, green, orange), stable light source wavelength, long-term continuous operation without temperature drift phenomenon, with a lifespan of up to 100000 hours, good reproducibility, and high accuracy. 11. The colorimetric cell adopts a standard 1cm cuvette, which has no mechanical displacement or wear. The optical path testing is precise and effectively shields external light interference, ensuring that the testing results are better than the national standard requirements. Technical parameters: 1.
