HJ Y09-301 AC/DC Portable Laser Particle Counter

Overview

The HJ Y09-301 AC/DC Portable Laser Particle Counter is a laboratory-grade, dual-power (AC/DC) airborne particle monitoring instrument engineered for high-reproducibility quantitative analysis of particulate contamination in cleanroom environments, controlled manufacturing spaces, and HVAC validation workflows. It operates on the principle of single-particle light scattering (SPLS) using a long-life 650 nm laser diode source (rated for ≥10 years under continuous operation). When aerosolized particles pass through the focused laser beam within the sensing chamber, each particle generates a pulse proportional to its projected area—enabling real-time classification and counting across six discrete size channels: 0.3 µm, 0.5 µm, 1.0 µm, 3.0 µm, 5.0 µm, and 10.0 µm. With a calibrated volumetric flow rate of 2.83 L/min (±5%), the device meets the minimum sampling volume requirements defined in ISO 14644-1 Annex B for Class 5–8 cleanrooms and aligns with the procedural rigor expected in pharmaceutical Grade A/B environments per EU GMP Annex 1 and FDA guidance on aseptic processing.

Key Features

• Integrated 5-inch full-color TFT touchscreen interface—first-of-its-kind in compact Chinese-manufactured particle counters—enabling intuitive navigation, parameter configuration, and on-device data review without external PCs.
• Dual-power architecture: supports uninterrupted operation via 220 V AC mains or internal 16.8 V / 2.2 Ah lithium-ion battery (≈5 h runtime); includes universal-input charging adapter (100–240 V, 50 Hz).
• High-stability imported diaphragm pump ensures consistent flow delivery across ambient temperature and pressure variations; optimized for energy efficiency and low acoustic emission (<45 dB(A)).
• Self-cleaning function validated to ≤10 minutes (95% confidence level, three consecutive zero-count readings), critical for minimizing carryover between sequential sampling locations.
• Comprehensive onboard data management: stores up to 5,000 complete sampling records—including timestamp, location ID, duration, delay, interval, and full-size-channel histograms—with recallable cumulative and differential count modes.
• Thermal printer integrated for immediate hard-copy reporting of raw counts, UCL calculations, and ISO/GMP compliance status per sample point.
• Stainless steel (SUS304) housing provides ESD-safe, corrosion-resistant mechanical integrity; compact footprint (170 × 170 × 160 mm) and lightweight design (2.4 kg with battery) support handheld use and tripod-mounted spatial mapping.

Sample Compatibility & Compliance

The Y09-301 AC/DC is designed for sampling non-hazardous, non-corrosive, non-oily ambient air and compressed gases (with optional inline filter). It complies with national metrological verification regulations JJF 1190–2008 and performance testing standard GB/T 6167–2007. Its sizing accuracy and counting linearity are traceable to NIST-traceable reference aerosols (e.g., PSL spheres). For regulated environments, the instrument supports cleanroom certification per ISO 14644-1:2015 (Classes 5–8), static/dynamic GMP qualification per EU Annex 1 (2022), and particulate limits outlined in USP . While the device itself does not embed 21 CFR Part 11 electronic signature functionality, its USB-exported CSV data files are compatible with validated LIMS or ELN platforms that implement audit trails, user authentication, and electronic record retention.

Software & Data Management

Data export is performed via standard USB interface to Windows-compatible hosts. The instrument generates time-stamped, UTF-8 encoded CSV files containing all measured parameters, including: sampling start/end timestamps, location identifier, flow rate confirmation, raw channel counts, calculated concentrations (particles/m³), and UCL-derived pass/fail flags. No proprietary software is required for basic data retrieval; however, third-party tools may be used for statistical process control (SPC), trend analysis, or integration into facility-wide environmental monitoring systems (EMS). All stored records retain immutable metadata—no post-acquisition editing is possible on-device, preserving data integrity in GLP/GMP contexts.

Applications

• Cleanroom certification and routine monitoring (ISO 14644-1, EU GMP Annex 1)
• Aseptic processing environment qualification (Grade A/B zones)
• HEPA/ULPA filter leak testing and efficiency verification
• HVAC system commissioning and recommissioning
• Medical device packaging line environmental surveillance
• Microelectronics fabrication area particulate baseline establishment
• University and industrial research labs requiring portable, traceable particle counting

FAQ

What calibration standards does the Y09-301 AC/DC comply with?
It conforms to JJF 1190–2008 (Chinese metrological verification regulation for airborne particle counters) and GB/T 6167–2007 (performance test methods). Factory calibration uses PSL reference particles traceable to national standards.
Can this unit be used for compressed air monitoring?
Yes—when paired with an appropriate pressure regulator and coalescing pre-filter to remove oil and moisture, it is suitable for ISO 8573-1 Class 2–4 compressed air particulate assessment.
Is the touchscreen interface programmable for multi-point UCL sampling protocols?
Yes. Users define UCL sampling locations (2–50 points), assign identifiers, set individual durations/intervals, and initiate automated sequences—all via the onboard GUI.
Does the built-in printer support custom report templates?
No—the thermal printer outputs fixed-format reports including date/time, location ID, channel counts, concentration values, and ISO/GMP pass/fail conclusions based on user-entered area classification.
How is data integrity maintained during battery-powered operation?
All measurements are written to non-volatile flash memory immediately upon acquisition; power loss during sampling does not corrupt previously saved records. Internal clock maintains timestamp accuracy within ±1 second over 6-minute intervals, as verified per JJF 1190–2008.
