Aria APS200 Series High-Flow Laser Particle Counter (28.3 L/min)

Overview

The Aria APS200 Series is a high-flow, real-time airborne particle counter engineered for continuous environmental monitoring in critical cleanroom, pharmaceutical manufacturing, semiconductor fab, and HVAC validation applications. Utilizing precision laser scattering photometry, the instrument detects and classifies particles suspended in air by measuring the intensity and angular distribution of light scattered from individual particles as they pass through a focused laser beam. With a calibrated volumetric flow rate of 28.3 L/min (1 cubic foot per minute), the APS200 delivers statistically robust particle concentration data—essential for ISO 14644-1 cleanroom classification, EU GMP Annex 1 compliance, and FDA 21 CFR Part 11–aligned monitoring systems. Its modular optical design supports multi-channel detection across configurable size thresholds, enabling simultaneous monitoring of sub-micron to coarse particulate fractions without compromising measurement integrity.

Key Features

• High-flow capability (28.3 L/min ±5%) ensures rapid representative sampling—critical for low-concentration environments and large-volume air handling systems.
• Laser diode light source with >50,000-hour operational lifetime guarantees long-term stability and minimal maintenance intervals.
• Configurable channel architecture: 2-, 4-, or 6-channel options support standardized thresholds (e.g., 0.3/0.5/0.7/1.0/3.0/5.0 µm) aligned with ISO 21501-4 and JIS B 9921 calibration requirements.
• Robust stainless-steel (SUS316L) enclosure rated for cleanroom-compatible installation and resistant to corrosion in humid or chemically aggressive ambient conditions.
• Dual analog outputs (4–20 mA, CH1/CH2 assignable per channel) enable direct integration into DCS, SCADA, or BMS platforms without external signal conditioning.
• Embedded Modbus TCP/IP and Modbus RTU protocols facilitate seamless interoperability with industrial automation infrastructure and centralized data historians.
• On-device color display (2.6-inch TFT) provides real-time channel-specific counts, alarm status, and system diagnostics—reducing reliance on external software during routine verification.

Sample Compatibility & Compliance

The APS200 Series is validated for use with ambient air, compressed air (via optional zero-filtered inlet), and HEPA-filtered process air streams. It meets the performance criteria defined in ISO 21501-4:2018 for light-scattering airborne particle counters, including specified counting efficiency curves, false count limits (<1 count/5 min), and maximum coincidence error thresholds. The instrument supports traceable calibration via NIST-traceable reference aerosols (e.g., PSL spheres), and optional factory-issued calibration certificates comply with ISO/IEC 17025 requirements. For regulated environments, the device’s firmware architecture supports audit-trail-enabled logging (when integrated with compliant software), aligning with GLP and GMP data integrity principles outlined in FDA Guidance for Industry (2022) and EU Annex 11.

Software & Data Management

Data acquisition and configuration are supported via standard Ethernet or RS-485 interfaces. Raw particle count data (per channel, per sampling interval) is timestamped and stored onboard in non-volatile memory (3000 records capacity). When deployed in networked configurations, the APS200 transmits structured JSON or Modbus register values to central servers running validated data management platforms—including those compliant with 21 CFR Part 11 for electronic records and signatures. Optional calibration reports and metrological traceability documentation are provided upon request, supporting periodic requalification per ICH Q5A and ISO 13485 quality system requirements.

Applications

• ISO Class 5–8 cleanroom environmental monitoring (continuous or scheduled sampling)
• Compressed air quality verification per ISO 8573-1:2010 (Class 0–2 particulate testing)
• Filter integrity testing and leak detection upstream/downstream of ULPA/HEPA units
• Pharmaceutical aseptic processing line qualification (e.g., isolator and RABS monitoring)
• Semiconductor front-end tool exhaust and mini-environment surveillance
• HVAC system commissioning and performance validation per ISO 14644-3

FAQ

What particle size channels are available on the APS200 series?
The APS200 offers 2-, 4-, or 6-channel configurations. Standard options include fixed thresholds at 0.3 µm and 0.5 µm, with selectable additional bins ranging from 0.7 µm to 10.0 µm—fully customizable per application-specific standards.
Is the APS200 suitable for compressed gas monitoring?
Yes—when equipped with an optional zero-filter and pressure-regulated inlet, the APS200 complies with ISO 8573-1 for compressed air particulate analysis; however, sample conditioning (drying, pressure reduction) must be implemented externally per system design.
Does the device meet FDA 21 CFR Part 11 requirements?
The APS200 itself does not store or manage electronic signatures, but its deterministic data output (Modbus registers, timestamped analog signals) is fully compatible with Part 11–compliant supervisory systems that implement audit trails, role-based access, and electronic signature workflows.
Can the APS200 operate unattended for extended periods?
Yes—the device supports continuous operation within its specified temperature and humidity range (5–35 °C, 20–95% RH non-condensing), with built-in power-fail recovery and non-volatile memory retention for up to 3000 sampling events.
What is included in the standard delivery package?
Standard accessories include isokinetic sampling probe, 1.5 m conductive sampling tube, dust cap, 10-pin terminal block, user manual, and factory calibration report; zero filter and metrological certification are optional extras.
