Kanomax 3887Lite / 3887Pro Handheld Laser Particle Counter

Overview

The Kanomax 3887Lite and 3887Pro are compact, handheld laser particle counters engineered for high-precision airborne particulate monitoring in controlled environments. Based on the light scattering principle—where a collimated laser beam interrogates aerosol-laden air and scattered photons are detected by a photodiode array—these instruments deliver traceable, repeatable particle concentration measurements across multiple discrete size channels. Designed to meet the stringent requirements of cleanroom qualification, environmental validation, and routine process monitoring, both models comply with international calibration and performance standards including ISO 21501-4 and JIS B9921. The 3887Pro extends analytical capability with five calibrated size thresholds (0.3, 0.5, 1.0, 3.0, and 5.0 µm), while the 3887Lite provides essential dual-channel verification (0.3 and 0.5 µm) plus 5.0 µm for coarse particle screening—making each model purpose-fit for specific regulatory and operational workflows.

Key Features

• Laser-based optical sensing with NIST-traceable calibration and documented counting efficiency per ISO 21501-4
• Fixed volumetric flow rate of 2.83 L/min (0.1 CFM) maintained within ±5% tolerance via integrated mass flow control
• 3.5-inch resistive touchscreen interface enabling intuitive navigation, real-time histogram visualization, and on-device parameter configuration
• Seven operational test modes—including single-shot, repeated sampling, continuous logging, statistical calculation, remote command execution, and standardized GB/T 16292-2010 and ISO 14644-1 protocols
• Robust data integrity architecture: automatic session resumption after power interruption; no loss of active sequence state or accumulated counts
• Built-in audit-ready metadata tagging (timestamp, location ID, operator code, instrument serial number) for GLP/GMP-aligned reporting

Sample Compatibility & Compliance

The 3887 series is validated for use with ambient air, HEPA-filtered supply air, and recirculated cleanroom atmospheres. It supports direct probe sampling as well as integration with isokinetic sampling manifolds (via optional 1-m conductive tubing). All measurement outputs conform to the classification criteria defined in ISO 14644-1:2015, US Federal Standard 209E (legacy reference), and China’s GB/T 16292–2010 for pharmaceutical cleanrooms. The device satisfies critical elements of FDA 21 CFR Part 11 when used with compliant software (e.g., Kanomax ParticleView™), including electronic signature support, secure user access levels, and immutable audit trails for all configuration changes and data exports.

Software & Data Management

Kanomax ParticleView PC software enables full post-acquisition analysis, trend plotting, statistical summary generation (mean, max, min, standard deviation), and automated report compilation in PDF or Excel formats. Raw datasets retain full channel-resolved time-series resolution and are exportable in CSV for third-party statistical packages. Communication is supported via USB 2.0 or RS-485 (Modbus RTU protocol), allowing seamless integration into facility-wide environmental monitoring systems (EMS) or SCADA platforms. Data encryption during transfer and local storage adheres to ISO/IEC 27001-aligned practices. Firmware updates are delivered through signed binary packages with SHA-256 hash verification.

Applications

These instruments serve mission-critical roles across industries requiring quantitative airborne particulate control: semiconductor fabrication (wafer fab tool monitoring), biopharmaceutical manufacturing (Grade A/B cleanroom certification per EU GMP Annex 1), medical device packaging validation, hospital isolation room verification, HVAC filter integrity testing, and aerospace assembly environment surveillance. They are routinely deployed during ISO 14644-2 compliance audits, cleanroom requalification, and root-cause investigations of contamination excursions. Academic and metrology laboratories utilize them for method development and inter-laboratory comparison studies under ISO/IEC 17025 quality management systems.

FAQ
