Product details










Product Introduction
Environmental protection stations and municipal water monitoring bureaus face an escalating challenge: balancing stringent regulatory oversight with high-volume sample processing workloads. Standard environmental compliance guidelines mandate routine surveillance of toxic heavy metals such as cadmium and lead across extensive watershed networks. When relying on single-sample analytical equipment, laboratories frequently experience sample backlog during regional baseline surveys or flood-season pollution surges, delaying vital environmental mitigation measures.
The HM-FZ2-SZ Dual-Channel Water Heavy Metal Detector engineered by HM Instruments resolves these throughput limitations through an advanced parallel electrochemical architecture. Operating in strict accordance with the JJF 2037-2023 calibration specification, the instrument features two completely isolated measurement channels. Technicians can execute simultaneous parallel tests on duplicate samples for rigorous QA/QC verification or analyze two distinct metal ions simultaneously, effectively halving the required analysis time.
Featuring a 10-inch Android touchscreen, dual patented magnetic elastic contact electrode docks, and single-use screen-printed electrodes, HM-FZ2-SZ operates without hazardous mercury drops or electrode polishing. Powered by a high-capacity 20,000 mAh internal lithium battery, it supports full-day stationary or mobile testing across watershed monitoring outposts, river cross-sections, and industrial wastewater treatment stations.
Applications
Municipal Water Quality Stations: Accelerated parallel screening of raw water intakes and drinking water reservoir feeds.
Wastewater Treatment Compliance Verification: Simultaneous monitoring of influent loading and effluent discharge compliance.
Regional River Basin Surveillance: Rapid duplicate testing across environmental boundary cross-sections to verify regulatory compliance.
Industrial Park Multi-Point Audits: Concurrent monitoring of distinct industrial discharge streams from plating and metallurgy plants.
Emergency Chemical Spill Delineation: Rapid high-volume sample throughput to track migration velocity and concentration gradients.
Agricultural Water Reservoir Audits: Dual-channel verification of irrigation canal waters to safeguard regional agriculture.
Key Features & Advantages
Independent Dual-Channel Operation: Two discrete electrochemical workstations run parallel stripping voltammetry routines without electrical cross-talk or timing constraints.
50% Analytical Turnaround Reduction: Double sample testing speed by analyzing parallel duplicates or two separate heavy metal targets concurrently.
Trace-Level 0.5 ppb Sensitivity: Delivers sub-ppb quantification limits for cadmium, lead, and mercury conforming to JJF 2037-2023 standards.
Zero-Digestion Clean Water Workflow: Water samples require simple acidification before direct analysis, avoiding lengthy acid heating steps.
Dual Patented Magnetic Holders: Elastic contact magnetic docking mechanism ensures instantaneous electrode insertion with stable electrical contacts.
Single-Use Screen-Printed Sensors: Eliminates dangerous mercury drop electrodes and messy diamond polishing pastes, ensuring complete bio-safety.
High-Definition 10-Inch Android Console: Displays dynamic voltammetric stripping peaks for both channels side-by-side in real time.
20,000 mAh High-Capacity Battery: Heavy-duty lithium power system enables all-day uninterrupted testing in remote locations without mains power.
Built-In Dual Report Thermal Printing: High-speed integrated printer generates immediate hardcopy records for both channels with distinct timestamps.
Expansive 50,000 Data Memory: Stores extensive historical datasets locally, with direct USB flash export and Wi-Fi cloud connectivity.
Scalable Sensor Library: Standard cadmium and lead testing protocols can be expanded via firmware to include arsenic, mercury, copper, and zinc.
Mobile Field & Stationary Bench Flexibility: At 5.7 kg with 390 mm × 296 mm × 156 mm dimensions, it transitions seamlessly between vehicles and laboratory benches. For single-operator portable tasks, inspect our portable single-channel heavy metal analyzer.

FAQ
Q1: Can the two channels on HM-FZ2-SZ test two completely different heavy metal elements simultaneously?
Yes. The two channels are backed by discrete potentiostat circuits and fully isolated firmware threads. Channel A can be configured to quantify cadmium while Channel B is running lead or copper analysis. Each channel executes its own pre-concentration deposition potential, equilibrium period, and stripping scan independently without cross-channel electrical interference.
Q2: How does dual-channel parallel testing reduce testing costs compared to purchasing two separate single-channel instruments?
HM-FZ2-SZ integrates dual workstations into a unified chassis sharing a single 10-inch Android console, power management system, and high-speed thermal printer. This consolidated design lowers equipment capital expenditure compared to dual separate units, while streamlining bench footprint, simplifying operator workflow, and centralizing data logging into one cohesive database.
Q3: How does the system prevent electrochemical cross-talk between the dual channels during simultaneous testing?
Each channel utilizes its own dedicated sample vessel, separate ground reference, and isolated drive circuitry. Because the electrochemical cells are physically and electrically decoupled, the accumulation potential or stripping current transient on Channel A has zero impact on the voltammetric baseline or peak amplitude of Channel B.
Q4: What is the recommended sample preparation for complex industrial wastewater samples?
For clean natural waters, straightforward acidification to pH 1-2 releases complexed metals for immediate testing. For turbid wastewater containing dense particulate matter, fats, or organic surfactants, we recommend rapid syringe filtration (0.45 µm) followed by acidification. If strong organic chelators are present, a brief thermal oxidation pre-treatment ensures complete liberation of heavy metal ions.
Q5: What are the key criteria when choosing between HM-FZ2-SZ and the single-channel HM-FZ1-SZ?
If your primary requirement is single-person mobile inspection where carrying weight is paramount, the HM-FZ1-SZ portable analyzer (4.0 kg) is ideal. However, if your team manages a fixed monitoring station, conducts mobile vehicle-based batch surveys, or routinely requires duplicate QA/QC validation, HM-FZ2-SZ provides double the analytical throughput, a larger 10-inch screen, and a 20,000 mAh battery for extended productivity.
