Pesticide residue detection instrument

Testing Standards: Designed in accordance with national standard methods (GB/T5009.199-2003), as well as the pesticide residue testing standards of the World Health Organization (WHO), the Food and Agriculture Organization of the United Nations (FAO), and the reference intake levels set by the Environmental Protection Agency (EPA). The enzyme inhibition rate colorimetric method is employed to rapidly and accurately detect the content of organophosphorus and carbamate pesticides in agricultural products such as fruits and vegetables.

Pesticide residue detection instruments are widely used for the rapid detection of organophosphorus and carbamate pesticides in food products such as vegetables, fruits, tea, grains, and agricultural by-products. Additionally, they can be used for on-site testing at fruit, vegetable, and tea production bases, agricultural wholesale markets, restaurants, schools, canteens, and for safety testing before fruit and vegetable processing in households.

The pesticide residue detection instrument can be equipped with a voice-guided function for user-friendly operation, has a built-in heating function, and can be configured with a high-capacity lithium-ion battery.

• Display: 7-inch high-sensitivity true-color touchscreen display with a user-friendly Chinese interface, providing intuitive and simple readings.

• Both acetylcholinesterase and butyrylcholinesterase reagents can be used, meeting national standards and Ministry of Agriculture standards.

• Automatically determine whether samples are qualified, with more intuitive test results.

• The instrument features recalibration, lock, and factory reset functions.

• Includes a menu library with over 100 vegetable names, categorized for management, and allows for the addition or removal of vegetable names as needed, as well as editing of vegetable names, with the ability to directly print vegetable names.

• Highly intelligent, the instrument has self-testing functions: it has power-on self-testing and zeroing functions, and can automatically detect repeatability.

• Testing channels: 20 testing channels, allowing simultaneous testing of multiple samples, with cyclic testing, ready to test upon placement. Each sample is controlled by the program to operate independently, without mutual interference.

• The light source uses imported ultra-high-brightness LEDs, offering low power consumption, high precision, strong stability, controllable light sources (unused light sources can be turned off), and fast response speeds.

• Intelligent operating system with a more user-friendly interface. The main controller uses a multi-core processor with a clock speed of 1.88 GHz, ensuring faster operation and greater stability.

• It features GPRS remote transmission functionality, allowing the insertion of a mobile phone SIM card to transmit data to a remote platform. It also supports Wi-Fi networking, enabling rapid data upload to a computer for management and statistical analysis.

• The printer uses a 5V serial port for printing, with options for manual or automatic printing. Results are available within three minutes, with the print format including the tester's name, absorbance difference, testing time, testing institution, sample name, and result determination.

• Features a USB 2.0 interface design, allowing direct data copying via a USB drive without the need for drivers, facilitating data storage and portability. It can also be directly connected to a computer for data querying, browsing, analysis, statistics, and printing.

• Features intelligent constant current voltage regulation and automatic light intensity calibration, ensuring no temperature drift in the light source during prolonged continuous operation.

• The instrument has built-in protection features, including the ability to set usernames and passwords to prevent unauthorized use.

• Powered by a DC 12V power supply for enhanced safety, and equipped with a 6A lithium-ion battery charger.
