Kanomax 3887Pro Handheld 5-Channel Laser Particle Counter

Overview

The Kanomax 3887Pro is a precision-engineered handheld laser particle counter designed for real-time, on-site monitoring of airborne particulate contamination in cleanroom environments and controlled manufacturing spaces. Utilizing a calibrated laser diode light source and advanced Mie scattering detection optics, the instrument measures particle concentrations across five discrete size channels—0.3, 0.5, 1.0, 3.0, and 5.0 µm—with counting efficiency validated per ISO 21501-4 and JIS B9921. Its fixed volumetric flow rate of 2.83 L/min (±5%) ensures metrological consistency during sampling, enabling direct comparability with regulatory test protocols defined in ISO 14644-1, GB/T 16292–2010, and Annex 1 of China’s Good Manufacturing Practice (GMP) guidelines for sterile pharmaceutical production.

Key Features

• Five-channel simultaneous particle sizing and counting for comprehensive contamination profiling
• 3.5-inch resistive touchscreen interface supporting intuitive navigation, real-time data visualization, and on-device parameter configuration
• Robust internal lithium-ion battery delivering up to five hours of continuous operation, supplemented by USB-C AC adapter support
• High-fidelity optical design minimizing coincidence loss (<5% at 2,000,000 particles/ft³) and ensuring traceable measurement integrity
• Flexible sampling logic including single-shot, repeat-cycle, continuous logging, statistical calculation, remote command execution, and standardized GB/ISO mode presets
• Automatic resume functionality: maintains session state and data continuity following power interruption or unexpected shutdown
• Integrated error diagnostics with clear visual alerts for low battery, flow deviation, laser output degradation, and exceedance of maximum count threshold

Sample Compatibility & Compliance

The 3887Pro is optimized for use in non-hazardous, indoor ambient air environments within temperature ranges of 10–40 °C and relative humidity up to 85% RH (non-condensing). It supports direct sampling via its built-in isokinetic inlet and accommodates optional extension tubing (e.g., 1 m conductive sampling tube) for remote probe placement. All count data and reporting structures conform to internationally recognized cleanroom classification frameworks—including ISO 14644-1 Class 1–9, GB/T 16292–2010 for pharmaceutical clean areas, and Annex 1 requirements for viable and non-viable particle monitoring in aseptic processing zones. Device firmware and calibration documentation are maintained to support GLP/GMP audit readiness and regulatory inspection.

Software & Data Management

The included PC-based analysis software enables secure import, time-synchronized visualization, statistical evaluation (min/max/mean), and export of raw count logs in CSV or PDF formats. Data files retain full metadata—including timestamp, location tag (user-defined), sampling mode, channel-specific counts, and environmental flags—ensuring full traceability. USB and RS485 communication interfaces allow seamless integration with facility monitoring systems, SCADA platforms, or centralized QA/QC databases. The software supports configurable report templates aligned with internal SOPs and external compliance mandates, including optional electronic signature capability compatible with FDA 21 CFR Part 11 requirements when deployed in validated environments.

Applications

This instrument serves critical quality assurance functions across industries where particulate control directly impacts product yield, sterility, and process reliability. Primary application domains include semiconductor fabrication cleanrooms (Class 1–100), LCD and OLED panel manufacturing, hard disk drive assembly, biopharmaceutical aseptic filling suites, hospital isolation rooms and operating theaters, HVAC filter validation, HEPA/ULPA filter leak testing, medical device packaging lines, aerospace clean assembly bays, and academic research laboratories conducting aerosol physics or inhalation toxicology studies. Its portability and rapid deployment make it especially valuable for routine surveillance, commissioning verification, and root-cause investigation of contamination excursions.

FAQ

What standards does the 3887Pro comply with for particle counting accuracy?
It meets counting efficiency specifications outlined in ISO 21501-4 and JIS B9921, and supports reporting formats required by ISO 14644-1, GB/T 16292–2010, and China GMP Annex 1.
Can the device operate without connection to a computer during field measurements?
Yes—the 3887Pro is fully autonomous with onboard storage for up to 7,000 sample records, local touchscreen control, and battery-powered mobility.
