Overview
The PULUODY DPC-2623 Online Laser Particle Counter is an industrial-grade, real-time airborne particulate monitoring system engineered for continuous environmental surveillance in regulated and mission-critical facilities. It operates on the principle of single-particle light scattering using a high-stability 650 nm laser diode and a dual-beam narrow-optic detection architecture—PULUODY’s proprietary “Seventh-Generation Dual-Laser Narrow-Beam” sensor platform. This optical configuration minimizes Mie scattering artifacts and improves signal-to-noise ratio across submicron and coarse particle ranges, enabling trace-level resolution down to 0.10 µm while maintaining linearity up to 25.0 µm. Designed specifically for compliance-driven environments, the DPC-2623 meets the metrological requirements of ISO 14644-1:2015 (cleanroom classification), ISO 21501-4:2018 (calibration and performance verification of light-scattering airborne particle counters), and China’s JJF 1190–2008 verification regulation. Its fixed flow rate of 2.83 L/min (0.1 cfm) ensures compatibility with international sampling protocols and facilitates direct comparison against reference instruments used in third-party certification audits.
Key Features
- Configurable multi-channel particle sizing: Six preset channel configurations (A–F) support flexible deployment—from pharmaceutical Grade A cleanrooms (0.10/0.20/0.50 µm) to HVAC duct monitoring (1.0–25.0 µm)
- Integrated environmental sensing: Onboard temperature and relative humidity measurement (–40 to 120 °C / 0–100% RH), with optional plug-in modules for CO, formaldehyde (HCHO), and differential pressure
- Dual-mode particle quantification: Simultaneous reporting in number concentration (particles/L), mass concentration (µg/m³), and filtration efficiency (% removal), each with independent alarm thresholds
- Robust industrial interface: 3.45″ wide-view TFT display with backlight, supporting both English and Chinese UI navigation without firmware reflash
- Comprehensive data integrity architecture: Local storage of ≥10,000 timestamped records with metadata (location ID, operator tag, calibration status); USB and RS232 ports enable GLP-compliant export and 21 CFR Part 11–enabled audit trail logging
- Enhanced operational safety: IP66-rated enclosure, intrinsically safe Ex d II CT4 certification, and six-layer electronic protection (overvoltage, overcharge, short-circuit, ESD, EMI, and condensation lockout)
Sample Compatibility & Compliance
The DPC-2623 is validated for continuous monitoring of compressed air, ambient indoor air, and process gases in non-corrosive, non-explosive atmospheres. It complies with ISO 8573-1:2010 (compressed air purity classes), ISO 14644-2:2015 (monitoring plan requirements), and EU GMP Annex 1 (2022) Section 8.42 for real-time viable and non-viable particle control. All factory calibrations are traceable to NIM (National Institute of Metrology, China) and documented per ISO/IEC 17025. Instrument-specific calibration certificates include uncertainty budgets compliant with JJF 1059.1–2012. Optional annual recalibration services are available through PULUODY-accredited regional labs—each report includes as-found/as-left data, drift analysis, and conformity statements against ISO 14644-1 class limits.
Software & Data Management
Firmware v3.2+ supports secure, time-stamped data acquisition with mandatory operator login and role-based access control. Raw particle count logs include GPS-tagged location metadata (when paired with external GNSS module), environmental sensor readings, and instrument health diagnostics (laser power decay, pump flow deviation, battery SOC). Data export formats include CSV (GLP-compliant headers), PDF summary reports, and XML for integration into SCADA or MES platforms (e.g., Siemens Desigo, Rockwell FactoryTalk). Audit trail functionality records all parameter changes, calibration events, and user logins with immutable timestamps—fully satisfying FDA 21 CFR Part 11 Subpart C requirements for electronic records and signatures.

FAQ
Does the DPC-2623 meet ISO 14644-1:2015 Class 5 (ISO Class 5) verification requirements?
Yes—the instrument’s 0.10 µm lower detection limit, ≤±10% repeatability, and certified flow stability satisfy the minimum performance criteria for ISO 14644-1:2015 Annex B. Calibration certificates include uncertainty values referenced to NIM standards.
Can the device be integrated into a central facility monitoring system (FMS)?
Yes—via RS232 or USB CDC virtual COM port, it supports Modbus RTU and custom ASCII protocol output. PULUODY provides integration guides compatible with Ignition SCADA, Siemens Desigo CC, and Honeywell Experion PKS.
Is third-party calibration supported by national metrology institutes?
Yes—NIM, CNAS-accredited labs (e.g., SGS Shanghai, BV Shenzhen), and EU Notified Bodies (e.g., TÜV Rheinland) accept DPC-2623 for periodic verification under ISO/IEC 17025. PULUODY supplies traceable calibration adapters and sampling manifolds.
What is the expected service life of the laser sensor under continuous operation?
Rated for >200,000 measurement cycles at nominal flow. Mean time between failures (MTBF) exceeds 15,000 hours when operated within specified environmental limits (5–45 °C, ≤90% RH non-condensing).
Does the firmware support 21 CFR Part 11-compliant electronic signatures?
Yes—version 3.2+ implements role-based authentication, biometric-ready login hooks (via optional RFID reader), and immutable audit trails with digital signature hashing (SHA-256) for all critical operations.
