This instrument is designed and manufactured based on the enzyme inhibition rate method in the national standard (GB/T 5009.199-2003) and agricultural standard method (NY/T 448-2001). It can accurately and quickly detect the residues of organophosphorus and carbamate pesticides in solid or liquid samples such as vegetables, fruits, agricultural products, tea, water quality, etc. Widely applicable to food safety monitoring departments at all levels, vegetable production bases, vegetable wholesale bases, agricultural markets, food supermarkets, food safety inspection mobile vehicles, health and epidemic prevention, environmental protection and other fields.
Instrument features:
1. Portable carrying case with cassette design, easy to operate, capable of measuring 5 samples simultaneously. Comprehensively improve detection efficiency;
2. Advanced cold light source, digital control, and data processing technology are adopted to ensure the stability of the light source and the accuracy of the data;
3. Large capacity storage, capable of storing over 50000 pieces of data, and able to query any set of raw data stored based on time or sequence number.
4. The original imported long-life heatless solid-state light source has high precision, stable performance, and controllable light source, greatly extending its service life.
5. Intelligently determine whether there is a sample in the channel and provide the test result within three minutes.
6. Unique enzyme reagent activity determination function, automatically determines whether the reagent is effective, and automatically alarms if it fails.
7. The universal design of acetylcholinesterase and butyrylcholinesterase allows for the selection of corresponding enzyme reagents for detection in the settings.
8. Each step during the operation process is accompanied by a sound prompt, and any malfunction or operational error is accompanied by an alarm prompt, which is displayed on the LCD screen.
9. Full color 5-inch LCD large screen display, with convenient button operation, and real-time display of various data, measurement results, and other operation prompts during the measurement process, achieving good human-machine dialogue function.
10. USB 2.0 interface, can be connected to a computer, and through the pesticide residue upper computer software, it can be integrated with the agricultural product safety detection information network database to instantly transmit monitoring results to the agricultural product safety monitoring information network, achieving real-time monitoring function. (Optional).
11. The instrument is equipped with a high-end brand micro thermal line printer, which can quickly print test results and facilitate data retention;
