Instrument model: HW-SJ12GE

Instrument Overview:

Capsule chromium rapid detectorAt present, it has been sold in various provinces across the country and has received praise from users. It can quickly detect the content of heavy metal chromium and set multiple sets of parameters according to customer needs. At present, the testing items include lead, cadmium, mercury, arsenic, and chromium in addition to chromium, and the software can be easily upgraded to meet customers' new testing requirements.
Chromium is a highly toxic heavy metal that easily enters human cells, causing damage to internal organs such as the liver and kidneys and DNA. Accumulation in the human body can be carcinogenic and may induce genetic mutations. Therefore, the Chinese Pharmacopoeia stipulates that capsules must be tested for heavy metal chromium before leaving the factory, and the content of heavy metal chromium in the capsules used exceeds the national standard limit of 2mg/kg. The use of tanning agents containing chromium in industrial processing of leather can lead to chromium residue. Industrial gelatin processed with this "blue alum skin" generally contains excessive levels of heavy metal chromium. It can be widely used in food and drug supervision systems, agricultural systems, quality supervision systems, industrial and commercial systems, health supervision systems, import and export inspection and quarantine centers, aquatic product quality supervision and inspection departments, aquatic product market supervision departments, aquaculture, commercial systems, economic and trade commissions, etc. It can also be applied to food production enterprises, large and medium-sized agricultural and sideline product wholesale markets, agricultural production bases, farmers' markets, supermarkets, hotels, restaurants, canteens, scientific research units, plant protection stations and other departments to conduct safety supervision of various foods and agricultural products, and to test quality control and unsafe indicators in food enterprises and other fields. This series of products includes a 12 channel capsule chromium rapid detector, a 24 channel capsule chromium rapid detector, and a 96 channel capsule chromium rapid detector.

7. High degree of intelligence: Equipped with detection project related programs, intelligent operation, no programming required to enter the testing state and automatically calculate results, the instrument can automatically diagnose system faults; The instrument undergoes self inspection of the light source, power supply, and circuit upon startup, without the need for manual calibration of similar instruments in China. Real time display of instrument performance, highly automated
8. Built in micro thermal printer, lifetime no need to replace ribbon, can also be connected to a universal printer, can automatically print test data and results, display detailed data such as test time, test number, sample name, test personnel, test data, result judgment, etc
9. The instrument detection data is automatically saved to the database, and can be queried and exported in chronological order to generate printed reports. The data can be directly uploaded to relevant regulatory departments for easy supervision and inspection. The instrument has standard hardware data interfaces, Ethernet ports, USB 2.0 interfaces, can be connected to computers, and can also connect to control devices such as mice and keyboards. It can use USB flash drives for data backup and exchange, and supports external storage such as USB flash drives.
10. ★ Provide graphic and text operation video function, facilitate the playback of teaching videos, and achieve on-site guidance and training.
11. The instrument light source adopts light-emitting diodes, which have the advantages of energy saving, environmental protection, long service life, and fast response speed.
12. ★ 8GB hard drive provides a large storage space, which can store more than 10 million sample test results, and the storage capacity can be doubled by inserting an SD card to expand the hard drive.
13. The instrument comes with a built-in working software system (instrument workstation software), using advanced open-source intelligent Android software as the operating system. It has functions such as inspection task management, batch import and export of tasks (supporting Excel, CSV, TXT and other formats), search and query statistics, workload statistical analysis, etc. It can view, delete and store measurement data at any time according to the testing date and testing number
14. The instrument is equipped with Bluetooth and can be remotely connected and operated with a tablet/Android phone/ISO system, as well as online. In addition to all testing functions of the host, it can also achieve powerful data processing and storage functions. As long as it is connected to the internet, the instrument can be upgraded, which is the same as the Android phone operating system/iOS, easy to learn and understand.
15. Provide complete accessory configuration, using beautiful and durable aluminum alloy toolbox, small and lightweight, convenient for users to operate in fixed or mobile laboratories. The accessories inside the box are complete, easy to maintain, and can be tested anytime and anywhere.
