Pesticide and Veterinary Drug Residue Detector

Product Overview

The HM-NSY Pesticide and Veterinary Drug Residue Detector is an integrated food safety rapid screening instrument developed by HM Instruments. Designed for laboratory and on-site testing environments, the instrument integrates multi-channel spectrophotometry and automated colloidal gold immunochromatography within a unified software and hardware platform. It enables rapid qualitative and quantitative determination of agricultural pesticide residues in fruits and vegetables, veterinary drug residues and hormones in fresh meat, and chemical contaminants in aquatic products.

Equipped with an ARM Cortex-A7 quad-core processor (1.88 GHz) running an intelligent Android operating system, HM-NSY delivers automated instrument self-inspection, multi-wavelength optical switching, and real-time result evaluation against national food safety limits. The instrument supports simultaneous detection across multiple independent channels, continuous sample introduction, automatic test card ejection, built-in high-speed thermal printing, and multi-mode wireless data synchronization with food safety supervision platforms.

Key Features

• Dual-Technology Integration: Houses both a 12-channel spectrophotometric detection module for enzyme-inhibition pesticide testing and an automated track-scanning colloidal gold immunochromatography module for rapid test strip reading.
• Automated Colloidal Gold Card Handling: Features motorized track transmission that automatically pulls in the test strip, scans the CT line with high-precision optical photogrammetry, automatically recognizes the CT line without manual intervention, and automatically ejects the card upon completion.
• 12-Channel Four-Wavelength Optical System: Each of the 12 optical channels is configured with four cold light source wavelengths (410, 520, 590, and 630 nm) and standard optical path switching mechanisms capable of expanding up to 64 wavelengths, supporting simultaneous independent sample analysis.
• Intelligent Constant-Current Stabilization: Features automatic light source intensity calibration, auto brightness adjustment, and constant-current voltage stabilization to eliminate thermal drift during extended continuous testing.
• Self-Diagnosis and Repeatability Verification: Built-in power-on self-test, automated zero calibration, and automated repeatability testing ensure measurement consistency and minimize operator errors.
• Android System with Responsive Touchscreen: Operated via a 7-inch color LCD touchscreen with intuitive UI, preset database containing over 100 testing projects, and support for editing custom sample names, inspection items, and submitter units.
• Built-in Multimedia Guidance: Features embedded step-by-step instructional operation videos accessible directly on the screen to guide operators through reagent preparation and testing workflows.
• Data Storage and Connectivity: Stores up to 200,000 test records, exports data to Excel format via standard driver-free USB interface, and provides Wi-Fi, 4G, GPRS, and Ethernet connectivity for real-time reporting to regulatory cloud platforms.
• Dual AC/DC Power Supply: Operates on standard 12V DC power, supports vehicle power connection, and accommodates an optional 6 Ah high-capacity rechargeable lithium battery for mobile field testing.
• Rugged Field Chassis: Enclosed in a portable, heavy-duty suitcase chassis with shock-absorbing internal foam, providing reliable protection during mobile transportation and field deployment.

Testing Items

The HM-NSY detector provides broad screening coverage across agricultural produce, animal products, and aquaculture:

• Fruit and Vegetable Pesticide Residues: Organophosphorus and carbamate pesticide residues evaluated via enzyme inhibition spectrophotometry; targeted pesticide screening via colloidal gold test strips (including imidacloprid, thiamethoxam, carbendazim, chlorothalonil, carbofuran, chlorpyrifos, acetamiprid, fipronil, and related compounds).
• Veterinary Drug Residues (Lean Meat Hormones / Beta-Agonists): Clenbuterol hydrochloride, salbutamol, ractopamine, hexestrol, quinestrol, and related synthetic hormone residues in animal tissues.
• Veterinary Drug Residues (Antibiotic Residues): Tetracyclines, sulfonamides, nitrofurans, quinolones/fluoroquinolones, florfenicol, gentamicin, streptomycin, amoxicillin, and erythromycin residues.
• Aquatic Product Safety: Malachite green, chloramphenicol, and nitrofuran metabolites (furazolidone metabolite AOZ, furaltadone metabolite AMOZ, nitrofurantoin metabolite AHD, nitrofurazone metabolite SEM).
• Meat Freshness and Quality Indicators: Volatile basic nitrogen (TVB-N), meat freshness, and histamine in meat and aquatic products.
