Overview
The Beckman Coulter MET ONE 6000 Remote Airborne Particle Counter is an ISO 21501-4 compliant optical particle counter engineered for continuous, real-time monitoring of airborne particulate contamination in critical controlled environments. Utilizing light-scattering principles—where individual particles passing through a focused laser beam generate detectable scattered-light pulses—the instrument delivers high-fidelity, traceable particle concentration data across user-selectable size thresholds. Designed specifically for integration into permanent monitoring networks, the MET ONE 6000 operates as a distributed sensing node within Facility Monitoring Systems (FMS), supporting regulatory adherence to ISO 14644-1, EU GMP Annex 1, and USP / requirements. Its compact form factor, low power consumption, and robust 304 stainless steel housing enable reliable deployment in cleanrooms, isolators, transfer hatches, and environmental air ducts without compromising structural integrity or calibration stability.
Key Features
- ISO 21501-4 certified optical detection with NIST-traceable calibration verification protocols
- Dual-flow-rate capability: configurable for either 0.1 CFM (2.83 L/min) or 1.0 CFM (28.3 L/min) sampling, supporting both high-sensitivity (0.3 µm) and standard (0.5 µm) counting applications
- Long-life laser diode source ensuring >50,000 hours of stable operation under continuous duty cycles
- Integrated diagnostics engine with multi-color LED status indicators for immediate visual identification of operational anomalies—including flow deviation, photodetector saturation, communication timeout, or internal sensor degradation
- Open-architecture communications suite supporting pulse, 4–20 mA analog, RS-232/RS-485 (Modbus RTU or proprietary FXB), and Ethernet TCP/IP protocols for seamless FMS interoperability
- Optional co-located temperature and relative humidity (RH/T) sensing module—enabling synchronized environmental metadata tagging within a single data stream per sampling point
- Low-profile mechanical design (17.15 × 11.43 × 31.75 cm) optimized for recessed wall-mount or duct-integrated installation, minimizing spatial footprint and airflow disruption
Sample Compatibility & Compliance
The MET ONE 6000 is validated for use in Class 1–Class 8 cleanrooms per ISO 14644-1 and supports qualification protocols aligned with FDA 21 CFR Part 11 when deployed with audit-trail-enabled FMS platforms. It meets the performance criteria defined in ISO 21501-4 for airborne particle counters—including sizing resolution, counting efficiency, false count rate, and coincidence loss limits—ensuring metrological consistency across global manufacturing sites. The device complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) electromagnetic compatibility standards. Its stainless steel enclosure satisfies material compatibility requirements for ISO Class 5 and higher environments, while its operating range (10–32 °C, 5–95% RH non-condensing) accommodates typical cleanroom HVAC conditions without thermal drift-induced measurement bias.
Software & Data Management
While the MET ONE 6000 operates autonomously as a hardware sensor node, it is fully compatible with industry-standard FMS software platforms—including Siemens Desigo CC, Honeywell Experion PKS, and custom SCADA implementations—via native protocol support. All digital outputs include timestamped packet headers compliant with IEEE 1588 Precision Time Protocol (PTP) synchronization when used with Ethernet-enabled controllers. Analog and pulse outputs maintain signal linearity across full dynamic range, enabling direct connection to PLC-based alarm logic systems. When integrated with GLP/GMP-compliant FMS infrastructure, raw count data, diagnostic flags, and optional RH/T values are archived with immutable timestamps, user-access logs, and electronic signature capabilities required for regulatory audits.
Applications
- Pharmaceutical aseptic processing: continuous monitoring of Grade A/B zones during sterile filling operations, supporting Annex 1 risk-based environmental control strategies

- Hard disk drive (HDD) manufacturing: cost-effective multi-point monitoring of head-disk interface assembly areas where nanoscale debris directly impacts yield
- Flat panel display (FPD) production: early-stage contamination trending in color filter and TFT array cleanrooms to preempt defect escalation
- Medical device packaging: validation of barrier integrity in ISO 5 laminar flow hoods and isolator glove ports
- Research-grade biosafety laboratories: supplemental aerosol monitoring in BSL-3 containment suites during high-risk agent handling
FAQ
Is the MET ONE 6000 suitable for ISO Class 1 (ISO 3) cleanroom applications?
Yes—the instrument’s 0.3 µm sensitivity mode, combined with its ≤1 false count/5 min specification and ISO 21501-4 compliance, supports routine monitoring in ISO Class 1–3 environments when installed per ISO 14644-2 sampling plan guidelines.
Can the MET ONE 6000 be calibrated in-house using NIST-traceable reference aerosols?
Field calibration verification is supported using ISO 21501-4–compliant polystyrene latex (PSL) microsphere suspensions and calibrated aerosol generators; however, full recalibration requires factory service or accredited third-party labs per ISO/IEC 17025.
Does the device support 21 CFR Part 11 electronic record requirements?
The MET ONE 6000 itself does not store or sign data—it functions as a sensor node. Compliance with 21 CFR Part 11 is achieved at the FMS software layer, where audit trails, role-based access controls, and electronic signatures are implemented.
What is the maximum allowable particle concentration before coincidence error exceeds 5%?
For the 6002/6003 configurations: 2×10⁶ particles/ft³ (7.06×10⁷ particles/m³); for the 6015 configuration: 4×10⁵ particles/ft³ (1.4×10⁷ particles/m³), as specified in ISO 21501-4 Annex B.
Is RH/T sensor integration mandatory or optional?
The RH/T probe is an optional accessory; the base unit performs particle counting independently. When added, it shares the same power and communication interface, delivering time-synchronized environmental metadata alongside particle counts.
