Overview
The Kanomax 3887C is a compact, battery-powered handheld laser particle counter engineered for rapid, on-site airborne particulate monitoring in cleanrooms, pharmaceutical manufacturing suites, hospital isolation rooms, and HVAC validation environments. It operates on the principle of single-particle light scattering—where aerosolized particles pass through a focused 650 nm diode laser beam, generating scattered light pulses proportional to particle size and number. The instrument processes these signals using real-time digital pulse-height analysis to classify and count particles across three user-selectable size thresholds: 0.3 µm, 0.5 µm, and 5.0 µm. Designed for compliance-driven applications, the 3887C delivers traceable, repeatable measurements aligned with internationally recognized cleanroom classification standards—including ISO 14644-1 (Class 5–8), GB/T 16292–2010 (Chinese pharmaceutical cleanroom standard), and the data integrity requirements of China’s 2010 Good Manufacturing Practice (GMP) regulations.
Key Features
- Laser-based optical sensing with high signal-to-noise ratio detection architecture for reliable low-concentration counting
- Fixed volumetric flow rate of 2.83 L/min (0.1 ft³/min), calibrated to NIST-traceable reference standards
- Three configurable particle size channels (0.3 µm, 0.5 µm, 5.0 µm) enabling flexible test protocols without hardware modification
- Backlit Chinese-language LCD interface optimized for field use under variable ambient lighting conditions
- Programmable pre-delay function (0–999 seconds) to eliminate operator-induced contamination during setup
- Auto-save functionality preserves all active sampling data upon unexpected power loss or battery depletion
- Internal memory supports storage of ≥1,000 sample records with timestamp, location tag, and statistical summaries (mean, max, min, SD)
Sample Compatibility & Compliance
The Kanomax 3887C is validated for use with ambient air, compressed air (after appropriate pressure regulation and drying), and laminar airflow environments. It is not intended for corrosive, explosive, or high-humidity (>80% RH non-condensing) atmospheres. Its measurement methodology satisfies the physical sampling and data reporting requirements of ISO 14644-1 Annex B (instrument calibration and verification), GB/T 16292–2010 Section 5 (sampling procedure and instrument performance), and China GMP Annex 1 (sterile product manufacturing controls). While the device itself does not provide electronic audit trails or user authentication, its raw count data output (CSV-compatible) may be integrated into validated LIMS or ELN systems supporting 21 CFR Part 11 compliance when paired with appropriate procedural controls.
Software & Data Management
Data export is performed via USB 2.0 interface to host PCs running Kanomax-provided Windows-compatible software (Kanomax Data Viewer v3.x). This application enables batch report generation compliant with ISO 14644-1 Table D.1 (cleanroom classification templates), trend analysis across multiple sampling points, and overlay of historical datasets. All stored records include embedded metadata: date/time stamp, sampling duration, flow rate confirmation, operator ID (manually entered), and environmental notes. No cloud connectivity or remote firmware updates are supported; firmware revisions require local installation via USB drive under controlled change management procedures.
Applications
- Cleanroom certification and routine monitoring per ISO 14644-1 Class 5–8 requirements
- Pharmaceutical facility qualification (IQ/OQ/PQ) and ongoing environmental monitoring (EM) programs
- Filter integrity verification (e.g., HEPA/ULPA upstream/downstream challenge testing)
- Medical device packaging area classification and maintenance verification
- University and industrial clean bench validation prior to critical process execution
- Post-maintenance verification of HVAC system performance following filter replacement or duct cleaning
FAQ
Does the 3887C support multi-point sequential sampling with auto-location tagging?
No—the instrument requires manual entry of location identifiers before each sampling session. It does not integrate with GPS or Bluetooth beacons.
Is calibration certificate included with shipment?
A factory calibration report (traceable to JCSS-accredited standards) is provided; full ISO/IEC 17025 calibration must be performed by an accredited third-party lab at recommended 12-month intervals.
Can the device measure particles below 0.3 µm?
No—its optical design and signal processing are optimized exclusively for the three specified channels (0.3, 0.5, 5.0 µm); sub-0.3 µm detection is outside its validated operating range.
What battery life can be expected during continuous operation?
Approximately 6–8 hours with alkaline AA batteries under typical 1-minute sampling cycles; rechargeable NiMH batteries are compatible but not supplied.
Is firmware upgrade capability available for future regulatory updates?
Yes—Kanomax releases periodic firmware updates via secure download portal; installation requires USB connection and administrative access to the host PC running Kanomax Data Viewer.
