HD-NK14
Introduction：
Pesticide Residue Detector detects pesticide residues in agricultural products using national standard rapid test cards per GB/T5009.199-2003. Widely used for markets, supermarkets and food safety rapid screening....
The HD-NK14 pesticide residue detector is a newly developed rapid-test instrument that adopts the national-standard test-card method, making detection faster and operation simpler. It is designed per GB/T 5009.199-2003 and the WHO, FAO and EPA residue-pesticide testing standards, and uses the enzyme-inhibition colorimetric method to rapidly and accurately detect organophosphorus and carbamate pesticide residues in vegetables, fruits, tea, grain and agricultural products.
Adopts the test-card method, eliminating redundant steps and improving the detection experience and efficiency.
Android smart system (version 7.1) for smoother and more convenient operation.
10.1-inch high-sensitivity true-color touchscreen with a better interactive user experience.
14 test-card channels for larger batch testing; place-and-test for higher efficiency.
Supports Wi-Fi and Bluetooth transmission for wireless data upload, plus driver-free U-disk copy.
Equipped with a food-safety management platform for long-term storage and short/long-term analysis to assist management.
Classified vegetable-name menu library; vegetable name and test unit information can be edited as needed.
Built-in thermal printer for selective printing of detailed test information.
The detection chamber automatically pops out and closes during testing.
Multi-core processor (main frequency 1.88 GHz) for faster operation and stronger stability.
