Overview
The HengaoDe CLJ-3016h Handheld Laser Particle Counter is an ISO 21501-4-compliant portable instrument engineered for real-time airborne particulate monitoring in controlled environments. It employs a high-stability semiconductor laser light source and a precision-calibrated optical sensing chamber to detect and size particles via light scattering principles—specifically Mie scattering theory—optimized for submicron to coarse particle detection (0.3–5.0 µm). Designed for GMP-grade cleanrooms (ISO Class 5–8), pharmaceutical manufacturing suites, HVAC validation, and laboratory containment verification, the device delivers traceable, repeatable concentration data in particles per cubic meter (pcs/m³), with built-in 95% Upper Confidence Limit (UCL) calculation per ISO 14644-1 Annex B. Its compact form factor, integrated lithium-ion battery, and dual-language interface support rapid deployment across multiple sampling points without external power dependency.
Key Features
- Simultaneous six-channel particle sizing (0.3, 0.5, 1.0, 2.0, 3.0, and 5.0 µm) with real-time concentration display
- 2.83 L/min volumetric flow rate certified per ISO 21501-4 and JJG 547–1988 metrological standards
- 320×240 high-resolution LCD with configurable English/Chinese UI, time/date stamping, and environmental parameter overlay (temperature, humidity, location ID)
- Onboard rechargeable Li-ion battery (16.8 V, 2600 mAh) enabling up to 8 hours of continuous operation with low-battery warning
- USB-based PC connectivity for remote control, live waveform viewing, and post-acquisition analysis using proprietary software
- Automatic self-cleaning cycle (<10 min) minimizing cross-contamination between sequential sampling events
- Compliance-ready data logging: timestamped records exportable directly to Excel (.xlsx) for audit trails and regulatory submissions
Sample Compatibility & Compliance
The CLJ-3016h is validated for use in non-hazardous, non-explosive ambient air environments typical of ISO-classified cleanrooms, aseptic processing areas, and sterile compounding facilities. It is not intended for corrosive, oily, or high-humidity (>85% RH) atmospheres without optional inlet filtration. The instrument meets the performance criteria specified in JJG 547–1988 (People’s Republic of China National Metrological Verification Regulation) and aligns with core technical requirements of ISO 21501-4:2018 for light-scattering airborne particle counters. While not FDA 21 CFR Part 11–certified out-of-the-box, its data export architecture supports integration into validated electronic record systems when paired with appropriate IT validation protocols (e.g., CSV, audit trail configuration, user access controls).
Software & Data Management
Data acquisition and visualization are managed through a Windows-compatible desktop application supporting real-time telemetry, historical trend plotting, and statistical summary generation (mean, standard deviation, UCL). All measurements include embedded metadata: operator ID, sampling point code, ambient temperature/humidity (via optional external probe), and battery status. Export formats include native .csv, Excel (.xlsx), and PDF reports compliant with internal QA documentation workflows. The software enables batch annotation, pass/fail threshold assignment per ISO 14644-1 limits, and automated report generation for routine environmental monitoring programs. Raw binary logs are stored with checksum integrity verification to satisfy GLP/GMP data retention expectations.
Applications
- Cleanroom certification and routine monitoring (ISO 14644-1 Class 5–8 verification)
- HVAC system commissioning and filter leak testing (e.g., HEPA/ULPA integrity checks)
- Pharmaceutical aseptic processing environment qualification (e.g., filling lines, isolators)
- Medical device packaging clean area surveillance
- Microelectronics fabrication facility contamination mapping
- University and contract research lab particulate baseline studies
FAQ
Does the CLJ-3016h require annual calibration?
Yes—per JJG 547–1988 and ISO 21501-4, recalibration is recommended every 12 months using NIST-traceable reference aerosols (e.g., PSL spheres) and flow verification against a primary rotameter or thermal mass flowmeter.
Can it measure particles below 0.3 µm?
No—the optical design and signal-to-noise threshold limit reliable detection to ≥0.3 µm; sub-0.3 µm analysis requires a condensation particle counter (CPC) or scanning mobility particle sizer (SMPS).
Is the device suitable for outdoor or industrial duct sampling?
Not without auxiliary conditioning: unfiltered high-dust or high-moisture airstreams may saturate the sensor or cause lens fouling; use of a cyclone pre-separator or heated inlet is required for such applications.
What is the warranty coverage?
HengaoDe provides a 12-month limited warranty covering defects in materials and workmanship; laser source lifetime is warranted for >30,000 operating hours under normal usage conditions.
How is data integrity ensured during USB transfer?
All exported files include embedded CRC-32 checksums and timestamped file headers; the software logs all export events—including user ID, filename, and UTC timestamp—in an immutable internal audit log.
