Overview
The Kanomax 3887Lite and 3887Pro are portable, laser-based optical particle counters engineered for high-fidelity airborne particulate monitoring in cleanroom validation, HVAC commissioning, pharmaceutical manufacturing, and semiconductor fabrication environments. Both models operate on the principle of light scattering: when aerosolized particles pass through a focused 650 nm laser beam, they generate scattered photons detected by a high-sensitivity photodiode. Signal amplitude is correlated to particle size via calibrated Mie scattering theory, enabling real-time classification across discrete size bins. The instruments comply with international metrological standards—including ISO 21501-4 for calibration accuracy and counting efficiency, and JIS B9921 for Japanese industrial verification—ensuring traceable, repeatable measurements required for regulatory audits.
Key Features
- Dual-model flexibility: The 3887Lite supports three size channels (0.3, 0.5, 5.0 µm) for cost-optimized routine checks; the 3887Pro adds two intermediate channels (1.0, 3.0 µm) to meet full ISO 14644-1 Class 3–9 classification requirements.
- Precision volumetric sampling: A thermally stabilized, brushless diaphragm pump delivers a nominal 2.83 L/min (0.1 CFM) flow rate with ±5% tolerance, certified per ISO 21501-4 Annex C for flow consistency under variable backpressure.
- Robust data integrity architecture: Internal storage retains up to 7,000 complete sample records—including timestamp, location tag, channel counts, and environmental metadata—with automatic recovery after power interruption during GB/T or ISO-mode sequences.
- Regulatory-ready reporting engine: On-device report generation conforms to GB/T 16292–2010 (Chinese pharmaceutical cleanroom standard), ISO 14644-1:2015 (cleanroom classification), and Annex 1 (EU GMP 2022) statistical requirements for UCL (Upper Confidence Limit) calculation.
- Field-deployable interface: A 3.5-inch resistive touchscreen enables glove-compatible operation; intuitive menu navigation supports rapid configuration of sampling duration, interval timing, cycle count, and alarm thresholds without PC dependency.
Sample Compatibility & Compliance
The 3887 series is validated for use with ambient air, compressed gases (via optional isokinetic probe), and filtered process air streams. It excludes oily, hygroscopic, or highly charged aerosols that may cause optical obscuration or electrostatic deposition on the sensing chamber window. All firmware and calibration protocols align with GLP/GMP documentation expectations: audit trails record operator ID, calibration date, sensor drift compensation, and firmware version. Device-generated reports include embedded digital signatures compliant with FDA 21 CFR Part 11 when exported via Kanomax’s optional PC software suite. Full traceability is maintained through NIST-traceable factory calibration certificates supplied with each unit.
Software & Data Management
Kanomax’s proprietary PC application (Windows 10/11 compatible) enables post-acquisition analysis, trend visualization, and automated compliance reporting. Raw data exports support CSV, PDF, and XML formats for integration into LIMS or MES platforms. The software implements role-based access control, electronic signatures, and immutable audit logs—meeting ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) principles. Communication interfaces include USB 2.0 (CDC class) and isolated RS-485 (Modbus RTU), allowing seamless integration with building management systems (BMS) or centralized cleanroom monitoring networks.
Applications
- Cleanroom certification and routine monitoring per ISO 14644-2 surveillance schedules
- HEPA/ULPA filter integrity testing (upstream/downstream scanning)
- Pharmaceutical aseptic processing environment qualification (ISO 14644-3, EU Annex 1)
- Semiconductor fab tool exhaust and mini-environment verification
- Hospital operating room and isolation ward air quality assurance
- Validation of laminar airflow workstations and isolators
- Environmental monitoring in biotech R&D labs and vaccine manufacturing suites
FAQ
Does the 3887Pro support UCL calculation per ISO 14644-1:2015?
Yes—the device computes Upper Confidence Limits automatically when configured in ISO mode using ≥3 sampling locations and ≥5 samples per location, following the statistical methodology defined in Annex D.
Can the instrument be used in compressed air lines?
Only with Kanomax’s optional pressure-regulated isokinetic sampling probe (Model 3887-SP), which reduces line pressure to ambient while maintaining laminar flow conditions at the sensor inlet.
Is firmware upgrade supported in the field?
Yes—updates are delivered via USB flash drive or PC software and preserve all stored calibration parameters and user configurations.
What is the recalibration interval recommendation?
Kanomax recommends annual recalibration against NIST-traceable PSL standards; however, users must verify frequency based on internal risk assessment per ISO/IEC 17025 Clause 6.5.
Does the device meet FDA 21 CFR Part 11 requirements for electronic records?
The hardware and bundled PC software provide foundational controls (audit trail, electronic signature, data encryption); full Part 11 compliance requires site-specific validation protocol execution and administrative SOPs.
