Kanomax 3887Lite / 3887Pro Portable Laser Particle Counter (2.83 L/min)

Overview

The Kanomax 3887Lite and 3887Pro are handheld laser particle counters engineered for high-precision airborne particulate monitoring in cleanroom validation, environmental qualification, and routine quality control applications. Based on the principle of light scattering detection—where particles passing through a focused laser beam generate scattered photons proportional to their size—the instruments deliver real-time, multi-channel counting across standardized size thresholds. With a calibrated volumetric flow rate of 2.83 L/min (equivalent to 0.1 CFM), they comply with international sampling conventions required for ISO 14644-1, GB/T 16292–2010, and Annex 1 of the EU GMP guidelines. The optical system meets ISO 21501-4 and JIS B9921 for counting efficiency, size resolution, and false count suppression—ensuring traceable, repeatable measurements essential for regulated environments.

Key Features

• Compact, ergonomic handheld design (87 × 200 × 55 mm; ~600 g) optimized for single-operator mobility during cleanroom mapping or HVAC duct surveys.
• 3.5-inch resistive touchscreen interface with intuitive navigation—supporting on-device configuration without external software.
• Dual-model flexibility: 3887Lite provides three-size channel detection (0.3, 0.5, 5.0 µm); 3887Pro extends to five channels (0.3, 0.5, 1.0, 3.0, 5.0 µm) for granular classification per ISO 14644-1 Class 3–9 or USP / requirements.
• Robust internal memory stores up to 7,000 complete sampling records—including timestamp, location tag, particle counts per channel, and statistical aggregates (min/max/mean).
• Intelligent continuity logic: In the event of power interruption during ISO or GB-mode testing, the device resumes from the last valid sampling point without data loss or sequence reset.
• Laser diode source with stable output and integrated diagnostics—automatically alerts for power decay or misalignment via on-screen error codes.

Sample Compatibility & Compliance

The 3887 series is validated for use in non-hazardous, non-corrosive indoor air environments—including ISO Class 3–9 cleanrooms, pharmaceutical aseptic processing suites, semiconductor fabrication tool zones, and hospital isolation rooms. It is not rated for explosive atmospheres (ATEX/IECEx) or high-humidity condensing conditions. All calibration and performance verification adhere to ISO 21501-4:2018 (Determination of particle size distribution—Single particle light interaction methods) and JIS B9921:2010. Counting accuracy is certified against NIST-traceable PSL standards; factory test reports include aerosol challenge results at 0.3 µm and 5.0 µm. The instrument supports audit-ready documentation workflows compliant with FDA 21 CFR Part 11 (when paired with validated Kanomax PC software), EU GMP Annex 11, and GLP/GMP data integrity expectations.

Software & Data Management

Kanomax PC Control Software (v3.x or later) enables secure, encrypted data transfer via USB or RS-485. Once imported, datasets support dynamic trend analysis—including spatial heatmaps, time-series overlays, and pass/fail evaluation against user-defined limits per ISO 14644-1 occupancy states (e.g., “at-rest” vs. “operational”). Reports export in PDF, CSV, or XML formats—with embedded metadata (operator ID, instrument serial number, calibration due date, environmental logs). Audit trail functionality records all parameter modifications, report generation events, and user logins—meeting ALCOA+ principles for attributable, legible, contemporaneous, original, and accurate data. Optional integration with building management systems (BMS) or LIMS is supported via Modbus RTU over RS-485.

Applications

• Cleanroom certification and periodic requalification per ISO 14644-2 and IEST-G-CC1002.
• Aseptic processing environment monitoring in pharmaceutical manufacturing (EU GMP Annex 1, FDA Guidance for Industry).
• HEPA/ULPA filter integrity testing via upstream/downstream scanning protocols.
• Microelectronics clean booth validation for wafer handling and photolithography zones.
• Hospital operating room and pharmacy compounding area environmental surveillance (USP , ).
• Research laboratory ambient air quality benchmarking and contamination source tracing.

FAQ

What is the difference between the 3887Lite and 3887Pro models?

The 3887Pro adds two additional size channels (1.0 µm and 3.0 µm), enabling full compliance with ISO 14644-1’s five-class particle distribution reporting. The 3887Lite is optimized for cost-sensitive applications where only baseline 0.3/0.5/5.0 µm monitoring is required.
Does the instrument require annual recalibration?

Yes. Kanomax recommends annual traceable recalibration using PSL reference aerosols in accordance with ISO 21501-4 Clause 8. Certificate of calibration includes uncertainty budget and as-found/as-left data.
Can the device be used in laminar airflow workstations?

Yes—provided the sampling probe is positioned outside the laminar curtain to avoid turbulence-induced undercounting. ISO 14644-3 Annex D specifies minimum distance (≥30 cm) from HEPA exit face.
Is the battery replaceable by the end user?

No. The sealed Li-ion pack is service-replaceable only by authorized Kanomax technical centers to maintain IP rating and optical alignment integrity.
How is data integrity ensured during USB transfer?

All transfers use CRC-32 checksum verification. The PC software logs transfer start/end timestamps, file hash, and operator credentials—satisfying FDA 21 CFR Part 11 §11.10(d) for electronic record transmission.
