FZ2-LS Dual-Channel Heavy Metal Analyzer for Grain Purchasing Stations

Product Introduction

During regional harvest campaigns, commercial grain silos, purchasing elevators, and food manufacturing enterprises experience massive logistical pressure. Fleets of trucks transport hundreds of tons of paddy rice, wheat, and corn daily. Bottlenecks at quality inspection gates cause costly demurrage and trucker dissatisfaction, yet compromising on heavy metal testing risks accepting contaminated crops that violate GB 2762-2022 safety limits. The HM-FZ2-LS Dual-Channel Heavy Metal Analyzer is purposely engineered to resolve this throughput challenge. By housing two fully isolated, independently driven electrochemical measurement channels inside a ruggedized chassis, the instrument enables continuous asynchronous screening—allowing an operator to insert and test a second sample while the first channel is mid-cycle. Backed by sensitive anodic stripping voltammetry (ASV) and digestion-free sample prep, the HM-FZ2-LS doubles testing productivity without requiring hazardous laboratory chemicals or slow external lab turnaround.

For central grain reserve headquarters requiring four concurrent testing channels, see our flagship four-channel grain heavy metal analyzer.

Applications

• Grain Purchasing Elevators & Stations: High-throughput screening of incoming grain trucks during peak harvest procurement seasons.

Technical Specifications

FAQ

Q: How does the dual-channel asynchronous operation work in practice?

A: Each of the two channels on the HM-FZ2-LS possesses its own independent potentiostat circuitry, electrode connector, and processor thread. An operator can load sample 1 into Channel A and start the run. While Channel A completes its 280-second deposition and stripping cycle, the operator can prepare and insert sample 2 into Channel B and trigger analysis immediately. The 10-inch touchscreen monitors both active channels side-by-side, displaying distinct curves and calculated results independently without timing clashes.

Q: Why is the HM-FZ2-LS preferred over benchtop atomic absorption for purchasing stations?

A: Benchtop atomic absorption spectrometers (AAS) require a climate-controlled laboratory, toxic acetylene and nitrous oxide gas cylinders, expensive exhaust ducting, and trained analytical chemists. Furthermore, wet acid digestion takes 2 to 4 hours per sample. The HM-FZ2-LS runs on safe ambient-temperature extraction reagents without digestion hoods, costs a fraction of an AAS, fits on any standard desk, and delivers quantitative results in under 20 minutes with minimal training.

Q: What battery runtime can operators expect from the 20,000 mAh pack?

A: The built-in 20,000 mAh industrial-grade lithium battery provides up to 8 to 10 hours of continuous dual-channel analytical operation, including screen illumination, processing, and intermittent thermal printing. This easily covers a complete 8-hour grain acquisition shift at remote silos or temporary open-air grain receiving stations where AC power outlets may be unavailable.

Q: Can Channel A and Channel B test different heavy metals simultaneously?

A: Yes. While both channels commonly run concurrent cadmium/lead screenings on different grain truckloads, the software permits customized element selections per channel. For instance, Channel A can be configured to screen cadmium in polished rice while Channel B performs a specialized lead protocol on wheat or corn, offering unprecedented analytical flexibility.

Q: How does the instrument prevent data tampering in commercial grain acquisitions?

A: The HM-FZ2-LS features an encrypted Android database architecture. Operators cannot modify historical numerical readings, curve baselines, or timestamps once an analysis is finalized. Each test record automatically binds operator credentials, batch identifier, raw voltammogram, and final concentrations. When printed or uploaded via Wi-Fi, the system generates a unique verification hash to ensure indisputable traceability.
