Agricultural Product Vegetable Pesticide Residue Detector

Product Name: Pesticide Residue Detector  Model: HW-SJ10NC   Manufacturer: Shenzhen Houwang

The ten-channel vegetable pesticide residue detector uses the enzyme inhibition rate method to quickly detect organophosphorus and carbamate pesticide residues. It features ten detection channels for vegetable pesticide residues.

The ten-channel pesticide residue detector can rapidly detect organophosphorus and carbamate pesticide residues in vegetables, fruits, grains, tea, and soil.

Instrument Overview:

The vegetable pesticide residue detector is designed based on the national standard GB/T5009.199-2003, utilizing the enzyme inhibition principle and photoelectric colorimetry. Under certain conditions, organophosphorus and carbamate pesticides inhibit the normal function of cholinesterase, with the inhibition rate positively correlated with pesticide concentration. Normally, the enzyme catalyzes the hydrolysis of the neurotransmitter metabolite (acetylcholine), and the hydrolysis products react with a color developer to produce a yellow substance. The absorbance change at 410nm over time is measured with a spectrophotometer to calculate the inhibition rate, which determines whether the sample contains organophosphorus or carbamate pesticide residues. This enables on-site rapid detection of such pesticide residues.

The ten-channel pesticide residue detector has ten detection channels for vegetable pesticide residues and can quickly detect organophosphorus and carbamate pesticide residues in vegetables, fruits, grains, tea, and soil. It is suitable for various agricultural testing centers, food and drug supervision departments, production bases, farmers' markets, supermarkets, health and epidemic prevention, environmental protection, vegetable wholesale markets, vegetable production bases, shopping malls, hotels, and other fields.

Features of the Ten-Channel Vegetable Pesticide Residue Detector:

1. Equipped with ten pesticide residue detection channels; features a color LCD touchscreen of 8 inches or larger, displaying measurement results in both Chinese and English for accurate and intuitive readings.

2. Capable of detecting organophosphorus and carbamate pesticide residues.

3. Convenient sample pre-treatment with no more than four reagents required; single sample testing time is less than 15 minutes, suitable for high-throughput parallel testing.

4. Automatically determines negative and positive results, combining qualitative rapid detection with quantitative analysis to enhance detection speed and operational efficiency.

5. Runs on an intelligent Android operating system, enabling data upload to monitoring centers or platforms. Can send detection data without GPRS functionality, providing interface data for networked detection and real-time monitoring with central control platforms.

6. Meets national standards for minimum detection limits and satisfies testing requirements. Provides provincial-level or higher test reports.

7. High level of intelligence: includes built-in programs for testing items, operates intelligently without programming, automatically calculates results, and self-diagnoses system faults. Performs self-checks on light source, power supply, and circuits upon startup, eliminating the need for manual calibration common in similar domestic instruments. Displays real-time instrument performance with high automation.

8. Built-in mini thermal printer with a lifetime ribbon-free design, automatically prints detection data and results, including detection time, sample ID, sample name, operator, detection data, and result judgment.

9. Automatically saves detection data to a database, allowing query and export of results in chronological order, and generates printable reports. Data can be directly uploaded to relevant regulatory departments for supervision and inspection. Equipped with standard hardware data interfaces, including USB 2.0, for computer connectivity.

10. Provides graphic and video operation guides, facilitating the playback of instructional videos for on-site training.

11. Uses imported LEDs for the light source, offering energy efficiency, environmental friendliness, long lifespan, and fast response.

12. Features a hard drive of 8GB or larger for extensive storage capacity, capable of storing over 10 million sample detection results. Storage can be expanded via SD card.

13. Comes with built-in workstation software based on the advanced open-source Android operating system. Includes functions for test task management, batch import/export (supporting Excel, CSV, TXT formats), search, query, statistics, workload analysis, and the ability to review or delete stored measurement data by date or ID.

14. Equipped with Bluetooth for remote operation with tablets/Android phones/iPhones, or connected operation. Besides performing all testing functions of the host, it supports powerful data processing and storage. Can be upgraded online, compatible with Android and iOS systems.

15. Includes a complete set of accessories in an attractive, durable aluminum alloy case. Compact and lightweight, suitable for fixed or mobile lab operations. The case contains all necessary accessories for easy maintenance and on-the-go testing.

16. Features built-in chart and graph data statistics, allowing users to query and analyze data by test item, category, unit, date, etc. Chart types include line graphs, pie charts, 3D pie charts, and bar charts.
