Overview
The Kanomax 3887 Handheld Laser Particle Counter is a compact, field-deployable optical particle counter engineered for rapid, on-site airborne particulate monitoring in cleanrooms, pharmaceutical manufacturing environments, hospital isolation rooms, and HVAC validation settings. It operates on the principle of light scattering—where particles drawn through a focused laser beam generate scattered photons proportional to their size and concentration. The instrument uses a single high-stability diode laser source and a calibrated photodetector array to resolve three user-selectable size channels: 0.3 µm, 0.5 µm, and 5.0 µm—enabling compliance-driven classification per ISO 14644-1 (Class 5–8), GB/T 16292–2010 (Chinese pharmaceutical cleanroom standard), and Annex 1 of China’s Good Manufacturing Practice (GMP) guidelines. Its fixed flow rate of 2.83 L/min (0.1 ft³/min) aligns with international sampling conventions for volumetric concentration reporting (particles/m³), and its real-time response supports dynamic assessment of filtration efficiency, personnel gowning performance, and environmental excursions.
Key Features
- Three configurable detection thresholds (0.3 µm, 0.5 µm, 5.0 µm) optimized for regulatory alignment across pharmaceutical, biotech, and microelectronics sectors.
- High-reproducibility optical sensing architecture with factory-traceable calibration against NIST-traceable reference aerosols.
- Integrated timing circuitry ensuring <±1 second deviation over 6-minute sampling intervals—critical for audit-ready data capture under GLP and GMP conditions.
- Backlit English-language LCD display with intuitive menu navigation, supporting both metric and imperial unit conventions.
- Onboard storage capable of retaining >10,000 sample records with timestamp, location tag (user-defined), channel counts, and statistical summaries (mean, max, min, SD).
- Auto-save functionality preserves all unsaved data upon unexpected power loss—ensuring continuity during battery-swapped or field-interrupted operations.
- Programmable delay start (0–600 seconds) eliminates operator-induced contamination bias during cleanroom entry protocols.
Sample Compatibility & Compliance
The Kanomax 3887 is validated for use with ambient indoor air, compressed gases (via optional inlet filter), and HEPA-filtered supply air streams. It does not support aggressive solvents, corrosive vapors, or high-humidity (>80% RH) environments without external conditioning. Regulatory conformance includes full traceability to ISO 21501-4:2018 (calibration and verification of airborne particle counters), GB/T 16292–2010 (test methods for airborne particle concentration in pharmaceutical cleanrooms), and ISO 14644-1:2015 (cleanroom classification). Its firmware embeds standardized test modes—GBMODE (for Chinese national standards), GMP (aligned with Annex 1 requirements), and ISO (for international cleanroom certification)—each enforcing mandatory sampling duration, volume, and reporting formats required for regulatory submissions.
Software & Data Management
Data export is supported via USB 2.0 interface to PC-based Kanomax KAN-View software (Windows-compatible), which provides batch report generation, trend visualization, and compliance dashboards. All exported datasets include embedded metadata: instrument ID, calibration date, operator ID, sampling location, and audit trail timestamps. The device logs internal diagnostics—including laser intensity drift, flow sensor stability, and battery voltage history—accessible for preventive maintenance scheduling. For regulated laboratories, the system supports 21 CFR Part 11-compliant workflows when paired with validated KAN-View configurations that enforce electronic signatures, role-based access control, and immutable audit trails.
Applications
- Cleanroom qualification and routine monitoring per ISO 14644-2 surveillance schedules.
- Pharmaceutical aseptic processing environment verification during media fills and equipment setup.
- HEPA filter integrity testing and leak detection using challenge aerosols (e.g., PAO, DOP).
- HVAC system commissioning and recommissioning in hospitals, labs, and semiconductor fabrication facilities.
- Environmental baseline studies prior to construction or renovation in controlled environments.
- Training and competency assessment for cleanroom gowning procedures using real-time particle burst detection.
FAQ
What calibration standards does the Kanomax 3887 follow?
It is calibrated using ISO 21501-4:2018–compliant polystyrene latex (PSL) spheres traceable to NIST SRM 1963, with annual recalibration recommended.
Can the device be used in explosive or hazardous atmospheres?
No—it is not intrinsically safe or ATEX-certified; operation is restricted to non-classified, general-purpose indoor environments.
Is remote data logging possible without PC connection?
Yes—internal memory retains all samples with full metadata; USB transfer is required only for archival or report generation.
Does it meet FDA requirements for pharmaceutical manufacturing?
Yes—when operated within defined SOPs and paired with validated software, it satisfies data integrity expectations under 21 CFR Part 11 and EU GMP Annex 1.
How is flow rate accuracy maintained over time?
A thermally compensated mass flow sensor with built-in diagnostic self-check ensures long-term stability; flow verification is advised quarterly using a primary standard flowmeter.
