HM-FZ1-LS Portable Grain Heavy Metal Rapid Analyzer

Product Introduction

The HM-FZ1-LS Portable Grain Heavy Metal Rapid Analyzer is an advanced electrochemical analytical instrument engineered for the rapid determination of toxic heavy metals, primarily cadmium (Cd) and lead (Pb), in cereal grains, milled rice, brown rice, wheat, and corn. Leveraging state-of-the-art anodic stripping voltammetry (ASV) combined with disposable screen-printed three-electrode strips, the instrument eliminates lengthy high-temperature acid digestion procedures, enabling on-site sample-to-result turnaround in under 20 minutes. Housed in a lightweight 4.0 kg chassis with a 7-inch color touchscreen and a built-in rechargeable 6,000 mAh battery, the HM-FZ1-LS delivers laboratory-grade quantitative precision for grain purchase checkpoints, agricultural cooperatives, and commercial milling facilities.

For grain depots requiring simultaneous multi-sample screening, explore our dual-channel grain heavy metal analyzer to double processing throughput.

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

1. Android Intelligent System: Intuitive graphical interface on a 7-inch high-definition color touchscreen ensures simple operation without specialized electrochemical training.
2. High Sensitivity ASV Technology: Anodic stripping voltammetry provides significantly higher sensitivity and accuracy than traditional colorimetric or X-ray fluorescence screening.
3. Digestion-Free Extraction: Room-temperature dilute acid extraction takes only minutes, eliminating hazardous boiling acids, hot plates, or microwave digestion vessels.
4. Single-Channel Fast Throughput: Dedicated electrochemical measurement cell delivers complete sample analysis in 280 seconds per run.
5. Patented Magnetic Electrode Holder: Elastic contact magnetic holder enables instant electrode strip insertion, eliminates mechanical friction, and guarantees stable signal transmission.
6. Disposable Three-Electrode Strips: Ready-to-use screen-printed electrodes require no manual polishing or chemical pre-cleaning, eliminating cross-contamination.
7. Multi-Element Expandability: Standard configuration tests cadmium and lead, with expandable firmware and protocols for arsenic, mercury, copper, and zinc.
8. Onboard Thermal Printer: High-speed built-in thermal printer produces immediate physical receipts and verifiable inspection records including QR codes.
9. Massive Data Storage: Internal memory safely records over 50,000 test logs, with convenient historical query, USB export, and Wi-Fi cloud synchronization.
10. Wireless OTA Upgrades: Embedded Wi-Fi module enables seamless wireless remote software and standard calibration curve updates.
