Instrument Overview:

The nitrate detector can quickly and quantitatively detect the content of nitrate in food and vegetables. 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 has12Channel nitrate detector24Channel nitrate detector96Channel nitrate detector.

1Having12One or more detection channels; greater than or equal to8.5Inch color LCD touch screen, with both Chinese and English input, displaying measurement results accurately and intuitively.

2The instrument reserves other detection programs and ports, and can easily add detection items according to future needs. It can be upgraded to a comprehensive type instrument for detecting veterinary drug residues, antibiotic residues, hormone residues, toxin residues, and chemical residues.

3Convenient sample pretreatment, with no detection reagents exceeding4Multiple reagents, single sample determination time less than15Minute, suitable for parallel and simultaneous detection of large quantities of samples.

4Automatically determine negative and positive results, detect data, achieve a combination of qualitative and quantitative analysis, and improve detection speed and operational efficiency.

5★ Built in intelligent operation computer, Qualcomm SnapdragonMSM8212Integrated chip, main frequency:1.2GImplement the upload of detection data to the monitoring center or platform, without the need forGPRSIn the functional state, it can be connected to the network to send detection data and provide interface data for network detection and real-time monitoring of the central control platform at any time.

6The minimum detection limit can meet the national standards and meet the testing requirements. Provide testing reports at or above the provincial level

7High 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

8Equipped with a built-in micro thermal printer, there is no need to replace the ribbon for life. It can also be connected to an external universal printer, which can automatically print test data and results, display detailed data such as test time, test number, sample name, test personnel, test data, and result judgment

9The 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,USB2.0Interface, can connect to a computer, can simultaneously connect to control devices such as mice and keyboards, can be usedUDisk for data backup and exchange, supportingUExternal storage devices such as disks.

10★ Provide graphic and text operation video function, facilitate the playback of teaching videos, and achieve on-site guidance and training.

11The instrument light source adopts light-emitting diodes, which have the advantages of energy saving, environmental protection, long service life, and fast response speed.

12★8GThe hard drive provides a large storage space that can store over 10 million sample test results, and can be plugged inSDExpanding the storage capacity of the card and hard drive exponentially increases the storage capacity.

13The instrument comes with a built-in working software system (instrument workstation software), using advanced open-source intelligenceandroidAs an operating system, the software has the ability to manage inspection tasks and batch import/export tasks (supports)Excel、CSV、TXTFunctions such as formatting, search and statistics, workload analysis, etc. can be used to view, delete, and store measurement data at any time based on the testing date and number

14★ The instrument is equipped with Bluetooth and can be connected to a tablet/Android phone/ISOThe system can be remotely connected or operated 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 and integrated with the Android mobile operating system/IOSSame, easy to learn and understand.

15Provide 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.
