KANOMAX 3887D Handheld Laser Particle Counter

Overview

The KANOMAX 3887D Handheld Laser Particle Counter is an optically engineered instrument designed for real-time, quantitative measurement of airborne particulate contamination in controlled environments. Based on the principle of light scattering—where particles passing through a focused laser beam generate scattered photons detected by a high-sensitivity photodiode—the 3887D delivers calibrated counts across five user-selectable size channels: 0.3, 0.5, 1.0, 3.0, and 5.0 µm. With a nominal volumetric flow rate of 2.83 L/min (equivalent to 0.1 CFM), it meets the sampling requirements defined in ISO 14644-1 for cleanroom classification and aligns with the operational scope of GB/T 16292–2010 for pharmaceutical clean area monitoring. As a direct evolution of the KANOMAX 3886 platform, the 3887D integrates enhanced firmware stability, extended data retention, and an intuitive full-Chinese graphical user interface—making it especially suitable for QC laboratories, pharmaceutical manufacturing sites, and HVAC validation teams operating under China’s 2010 GMP Annex 1 framework.

Key Features

• Laser-based optical detection system with dual-stage signal amplification for improved signal-to-noise ratio at low-concentration sampling
• Five discrete particle size thresholds (0.3, 0.5, 1.0, 3.0, 5.0 µm) selectable via on-device menu—enabling flexible compliance mapping to ISO, GMP, or GB-mode protocols
• Integrated timing module with ±1 second deviation over 6-minute sampling intervals, ensuring traceable temporal alignment for audit-ready reports
• Flow stability maintained within < ±1 particle/5 min, verified against NIST-traceable flow calibrators during factory certification
• Auto-save functionality preserves all active sampling parameters and accumulated counts upon unexpected power loss—resuming from last valid state on reboot
• Adjustable high-luminance LCD backlight optimized for low-illumination cleanroom pass-through zones and glovebox interfaces
• Configurable pre-delay start (0–600 s) eliminates operator-induced turbulence during critical sampling initiation

Sample Compatibility & Compliance

The KANOMAX 3887D is validated for use with ambient air, compressed air (after appropriate filtration and pressure regulation), and nitrogen-purged enclosures—provided inlet aerosol loading remains below 1×10⁶ particles/m³ for 0.3 µm and below 1×10⁵ particles/m³ for 5.0 µm to prevent coincidence error. Its calibration traceability originates from KANOMAX’s ISO/IEC 17025-accredited metrology laboratory in Yokohama, Japan. The device satisfies the minimum performance criteria specified in ISO 21501-4 for light-scattering airborne particle counters and supports documentation workflows compliant with FDA 21 CFR Part 11 when paired with KANOMAX’s optional PC-based reporting software (KanView v3.x). It is routinely deployed in Grade A–D cleanrooms per EU GMP Annex 1, sterile processing areas under USP , and environmental monitoring programs governed by China’s 2010 GMP requirements.

Software & Data Management

Internal storage accommodates up to 10,000 sampling records—including timestamp, location ID, channel-specific counts, and operator notes—with built-in statistical functions (mean, standard deviation, max/min, and % exceedance vs. limit). Data export is supported via USB 2.0 to CSV or proprietary .kpd format. Optional KanView software provides GLP-compliant report generation with electronic signature support, audit trail logging (including parameter changes and data exports), and trend visualization across multiple instruments. All firmware updates are delivered as digitally signed packages to ensure integrity and version control in regulated environments.

Applications

• ISO 14644-1 cleanroom certification and routine monitoring (Class 5–8)
• Pharmaceutical aseptic processing environment qualification (fill-finish lines, isolators, RABS)
• Medical device packaging clean area verification per ISO 13485
• HEPA filter integrity testing support (upstream/downstream differential counting)
• Facility commissioning and HVAC system balance validation
• Education and research labs requiring portable, standards-aligned particle characterization

FAQ

Does the KANOMAX 3887D require annual recalibration?
Yes—KANOMAX recommends annual recalibration against reference aerosols (e.g., PSL spheres) at an ISO/IEC 17025-accredited facility to maintain traceability to SI units.
Can the 3887D be used in compressed gas lines?
Only after pressure reduction to atmospheric and installation of a coalescing filter; direct high-pressure sampling may damage the flow sensor and optical chamber.
Is the Chinese UI available in other languages?
No—the 3887D firmware is fixed to Chinese language; international variants (e.g., 3887A) feature English-only interfaces.
What is the maximum allowable particle concentration for accurate counting?
For 0.3 µm channel: ≤1×10⁶ particles/m³; for 5.0 µm channel: ≤1×10⁵ particles/m³—exceeding these thresholds introduces >5% coincidence error.
Does the device support external trigger inputs or analog outputs?
No—the 3887D operates as a standalone unit without I/O ports; remote control and data streaming require USB connection and KanView software.
