Product Introduction
The HM-FZ3-LS Four-Channel Grain Heavy Metal Rapid Analyzer is the premier flagship electrochemical workstation designed specifically for massive sample volumes encountered by national grain reserves, provincial quality inspection institutes, and large food conglomerates. Featuring four fully isolated testing channels, the HM-FZ3-LS allows operators to process four independent grain specimens simultaneously or initiate sequential runs under distinct testing parameters. Powered by high-precision anodic stripping voltammetry (ASV) and proprietary digestion-free extraction, the system delivers precise, sub-ppb quantifications of cadmium (Cd) and lead (Pb) without the hazardous overhead of acid digesters. With its large 10-inch Android command interface, 20,000 mAh industrial-grade power pack, integrated thermal printer, and full cloud connectivity, the HM-FZ3-LS sets a new benchmark in analytical efficiency.
For compact mobile operations with lighter sample volumes, consider our highly portable portable grain heavy metal rapid analyzer.
Applications
- Rice and Brown Rice: Determination of cadmium and lead in milled polished rice, raw brown rice, and paddy crops before and after milling.
- Wheat and Corn: Rapid contaminant screening for commercial cereal grains and raw ingredients at processing mills.
- Grain Silos and Depots: Inbound grain testing at reception gates to prevent off-spec grain consignments from entering storage.
- Food Manufacturing: Quality control verification for flour mills, noodle factories, breakfast cereal lines, and baby food processors.
- Agricultural Inspection: On-site food security screening for harvest grading and grain market surveillance.
Functional Performance & Features
- Quad Independent Channels: Four completely decoupled electrochemical cells enable simultaneous, non-interfering parallel testing across four separate samples.
- Maximum Sample Throughput: Up to 4x testing speed drastically reduces turnaround times during major grain procurement campaigns.
- 10-Inch High-Definition Interface: Industrial Android platform displays all four channels simultaneously with real-time voltammetric curve rendering.
- Digestion-Free Fast Pretreatment: Rapid room-temperature extraction dissolves metal ions in under 10 minutes without explosive heating or toxic acid fumes.
- Quad Magnetic Contact Holders: Patented magnetic elastic electrode mounts protect connectors from friction and maintain low impedance contact.
- Zero-Cross-Contamination Electrodes: Disposable screen-printed sensor strips are discarded after single use, eliminating manual electrode polishing steps.
- Rigorous Regulatory Alignment: Fully compliant with JJF 2037-2023 calibration guidelines and GB 2762-2022 national contaminant limitations.
- 20,000 mAh Industrial Lithium Pack: High-capacity onboard energy system guarantees uninterrupted full-shift field operation without main power grid access.
- Traceable Thermal Receipts: Built-in printer instantly outputs formal inspection vouchers detailing operator ID, batch numbers, concentrations, and verification QR codes.
- Enterprise LIMS & Cloud Integration: Seamless Wi-Fi and USB communications provide real-time batch synchronization with regional quality surveillance systems.
