Aria AP133/AP136 Handheld Laser Particle Counter

Overview

The Aria AP133 and AP136 are precision-engineered handheld laser particle counters designed for real-time airborne particulate monitoring in critical environments—including cleanrooms, pharmaceutical manufacturing suites, hospital isolation rooms, and semiconductor fabrication facilities. Both models operate on the principle of light scattering: a collimated laser beam illuminates individual particles drawn through the sensing volume by an integrated diaphragm pump; scattered photons are detected by a high-sensitivity photodiode array and converted into electrical pulses proportional to particle size. Pulse height analysis enables classification across user-selectable channels—3-channel (AP133) or 6-channel (AP136)—with sizing traceability anchored to ISO 21501-4 and JIS B 9921 standards. The instruments deliver calibrated concentration data (particles/m³) with full compliance to ISO 14644-1 classification protocols and EU GMP Annex 1 requirements for dynamic and static grade verification (Grades A–D). Their compact form factor, robust ABS housing, and field-deployable battery life support rigorous environmental qualification, routine surveillance, and audit-ready documentation.

Key Features

• Laser-based optical detection with long-life diode source ensuring stable signal integrity over extended operational cycles
• Two model variants optimized for application scope: AP133 (0.3–5.0 µm, 3 channels) for ISO Class 5–9 environments; AP136 (0.3–10.0 µm, 6 channels) for comprehensive GMP-grade validation including ≥5.0 µm monitoring
• ISO 21501-4–compliant counting efficiency (50% @ 0.3 µm, ≥99% @ ≥0.45 µm) and zero-count performance (<1 count/5 min)
• Configurable sampling logic: manual trigger, timed auto-sequence, ISO 14644-1 mode (multi-point, multi-location), and GMP Annex 1 mode (dynamic/static grade mapping with room ID tagging)
• Integrated data security architecture: password-protected access, encrypted local storage (15,000 records on AP136), and audit-trail-capable PC software compliant with FDA 21 CFR Part 11
• Dual communication stack: simultaneous BLE and Ethernet (RJ45) for remote supervision, live telemetry, and centralized fleet management
• High-fidelity human interface: resistive touchscreen with tactile feedback button, multilingual UI (English/Japanese), and intuitive menu navigation for untrained operators

Sample Compatibility & Compliance

The AP133/AP136 is validated for use with ambient air and filtered process gases (non-corrosive, non-explosive, dew point below operating range). It meets ISO 21501-4 for instrument performance verification and supports regulatory workflows under ISO 14644-1 (cleanroom classification), EU GMP Annex 1 (sterile manufacturing), USP (injectables particulate testing), and ICH Q5A (viral clearance validation support). Optional temperature/humidity probe extends environmental correlation capability for ISO 14644-2 stability assessments. All units ship with NIST-traceable calibration certificates and zero-filter verification kits. Device firmware and PC software are designed for GLP/GMP-aligned environments—supporting electronic signatures, change control logs, and 21 CFR Part 11–compliant audit trails when used with validated configuration.

Software & Data Management

Aria’s proprietary PC software provides full instrument control, real-time dashboard visualization, automated report generation (PDF/CSV), and database synchronization. It enables batch-level metadata tagging (operator ID, location, ISO class, sampling protocol), trend analysis across time-series datasets, and deviation flagging against pre-defined alert thresholds. Data export complies with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Firmware updates are delivered via signed packages with SHA-256 checksum verification. Remote firmware deployment and configuration push are supported over Ethernet or BLE for enterprise-scale deployments.

Applications

• Cleanroom certification and periodic requalification per ISO 14644-1 and ISO 14644-2
• Pharmaceutical aseptic processing environment monitoring (Grade A–D zones)
• Medical device packaging line particulate surveillance
• HVAC system performance validation and filter integrity testing
• Microelectronics clean manufacturing process control
• Research laboratory ambient air quality baseline studies
• Post-maintenance verification of contamination control systems

FAQ

What standards does the AP133/AP136 comply with for calibration and performance verification?
ISO 21501-4, JIS B 9921, ISO 14644-1, and EU GMP Annex 1. Calibration certificates are provided with each unit and include traceability to national metrology institutes.
Can the instrument be used in explosive or hazardous atmospheres?
No. The AP133/AP136 is not intrinsically safe and is rated for use only in non-hazardous, non-corrosive environments per IEC 60079-0.
Is remote data retrieval possible without physical connection?
Yes—via built-in Bluetooth Low Energy (BLE) or Ethernet (RJ45) interfaces. Real-time streaming and historical record download are supported through Aria’s PC software.
How is data integrity ensured during power loss or unexpected shutdown?
All measurements are written to non-volatile flash memory with atomic commit logic. Partial records are discarded; only fully completed sampling events are stored.
Does the device support integration with building management systems (BMS) or LIMS?
Yes—via TCP/IP API (Ethernet) and standardized CSV/JSON export. Custom middleware integration is supported under Aria’s OEM partnership program.
