Overview
The COMECAUSE IN-CL2 Laser Particle Counter is a portable, high-precision airborne particle monitoring instrument engineered for real-time quantification of suspended particulate matter in cleanroom and controlled environments. It operates on the principle of single-particle light scattering: when aerosolized particles pass through a focused semiconductor laser beam (wavelength stabilized, >30,000 h lifetime), they generate scattered light pulses proportional to their size. These pulses are detected by a high-sensitivity photodetector and classified into six discrete size channels—0.3, 0.5, 1.0, 3.0, 5.0, and 10.0 µm—enabling simultaneous multi-channel counting at a nominal sampling flow rate of 2.83 L/min (0.1 cfm). Designed for compliance with international cleanroom classification standards—including ISO 14644-1, Fed Std 209E, and China’s GB/T 6167–2007—the IN-CL2 delivers statistically robust concentration data, automatically computes Upper Confidence Limit (UCL) at 95% confidence per ISO 14644-1 Annex D, and performs real-time洁净度 (cleanliness class) evaluation against user-defined or standard thresholds.
Key Features
- Android 7.1 operating system with intuitive GUI, supporting multi-touch gesture navigation and customizable measurement workflows.
- Integrated environmental sensors: high-accuracy digital hygrometer and thermistor (±0.5 °C), plus barometric pressure sensor (±0.5 kPa), enabling real-time compensation of volumetric flow and particle concentration calculations.
- Optimized optical chamber design minimizing stray light; enhanced signal-to-noise ratio ensures improved detection fidelity—particularly critical for sub-micron particle resolution at 0.3 µm.
- FDA 21 CFR Part 11-compliant audit trail functionality: all user actions (login/logout, parameter changes, calibration events, data exports) are timestamped, user-identified, and immutable—fully traceable for GMP/GLP-regulated facilities.
- Dual-mode connectivity: secure Wi-Fi and Bluetooth 4.2 for wireless data transmission to local networks or cloud-based supervision platforms; USB-A port supports driver-free mass storage mode for rapid field data retrieval via U-disk.
- Built-in thermal printer with configurable channel selection—users may print only selected size bins (e.g., ≥0.5 µm and ≥5.0 µm) directly from device interface without external software.
- Ergonomic telescoping tripod mount with 360° azimuth and ±90° elevation adjustment—optimized for wall, ceiling, or ISO-standard sampling port integration per ISO 14644-2 Annex B.
Sample Compatibility & Compliance
The IN-CL2 is validated for use in non-hazardous, non-corrosive, non-oily aerosols within ambient air and filtered process gases. It meets metrological requirements specified in JJF 1190–2008 (Calibration Specification for Laser Airborne Particle Counters) and performance verification criteria outlined in GB/T 6167–2007. Its counting efficiency curve satisfies ISO 21501-4:2018 for light-scattering airborne particle counters. The instrument supports both static (at-rest) and dynamic (in-operation) testing protocols required under EU and US FDA Annex 1 and current Good Manufacturing Practice (cGMP) guidelines. All firmware and embedded software undergo periodic version-controlled validation; configuration files and calibration logs are digitally signed and stored with cryptographic integrity checks.
Software & Data Management
Data acquisition, visualization, and reporting are managed via the embedded Android OS and optional COMECAUSE CleanTrack™ Supervisory Platform. On-device storage retains up to 100,000 complete sampling records—including raw channel counts, environmental metadata, operator ID, location tags, and UCL values—with searchable indexing and CSV/PDF export capability. Wireless synchronization enables centralized aggregation of multi-instrument datasets across distributed cleanroom zones. The platform supports trend analysis (e.g., 7-day rolling averages, shift-wise deviation mapping), automated alerting (email/SMS upon threshold breach), and electronic signature-enabled report generation compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).
Applications
The IN-CL2 serves as a primary verification tool in regulated manufacturing and research settings requiring ISO Class 3–8 (ISO 14644-1) or Class 10–100,000 (FS-209E) environment monitoring. Key application domains include: sterile pharmaceutical production suites (aseptic filling lines, isolators, RABS); semiconductor fabrication cleanrooms (lithography, etching, packaging); medical device assembly areas; biotech cell culture labs; food-grade packaging environments subject to HACCP and SQF standards; HEPA/ULPA filter integrity testing (via upstream/downstream challenge measurements); and aerospace component assembly where particulate-induced surface defects compromise optical or mechanical performance.
FAQ
Does the IN-CL2 support ISO 14644-1:2015 UCL calculation?
Yes—the device implements Annex D algorithms to compute Upper Confidence Limits for all six particle size channels based on user-defined sample volume and number of measurement locations.
Can the instrument be calibrated traceably to NIST or national metrology institutes?
Yes—COMECAUSE provides factory calibration certificates traceable to CNAS-accredited reference standards; users may also perform field verification using PSL (polystyrene latex) monodisperse aerosols per ISO 21501-4.
Is the internal battery certified for air transport (IATA/UN38.3)?
Yes—the 74 Wh Li-ion battery complies with IATA Packing Instruction 965 Section II and is approved for carry-on and checked baggage under applicable airline regulations.
What is the minimum detectable particle concentration?
The theoretical lower limit is governed by zero-count performance: ≤1 false count per 5 minutes, enabling reliable measurement down to ~10 particles/m³ at 0.3 µm in low-background environments.
How does the device handle condensation or high humidity during sampling?
The IN-CL2 incorporates active desiccant-assisted inlet conditioning and real-time RH compensation algorithms; however, operation above 85% RH is not recommended to prevent optical window fogging and sensor drift.
