Junray ZR-1630 Portable Optical Particle Counter

Overview

The Junray ZR-1630 Portable Optical Particle Counter is a laboratory-grade, battery-powered instrument engineered for quantitative airborne particulate monitoring in controlled environments. It operates on the principle of single-particle light scattering—using a stabilized laser diode source to illuminate aerosol particles drawn through an optimized sensing volume. When particles pass through the beam, scattered light intensity is detected by a high-sensitivity photodetector; pulse height analysis enables real-time classification and counting across six user-selectable size channels (0.3 µm, 0.5 µm, 1.0 µm, 3.0 µm, 5.0 µm, and 10.0 µm). The device maintains a precisely regulated sampling flow rate of 28.3 L/min via an integrated vacuum pump and closed-loop mass flow control circuitry, ensuring consistent volumetric throughput essential for ISO 14644-1 and EU GMP Annex 1 compliant cleanroom certification testing.

Key Features

• Integrated dual-stage flow control system with built-in vacuum pump and thermal mass flow sensor for stable 28.3 L/min operation (±2% accuracy)
• Six simultaneous particle size channels covering 0.3 µm to 10.0 µm—aligned with standard cleanroom classification thresholds
• Onboard HEPA filter (≥99.97% @ 0.3 µm) for exhaust air purification, preventing cross-contamination during repeated measurements
• Self-cleaning cycle completed in under 5 minutes—minimizing carryover between sampling locations
• 7-inch capacitive touchscreen with bilingual (Chinese/English) graphical interface and intuitive navigation for field deployment
• Internal rechargeable lithium-ion battery supporting >4 hours of continuous operation—enabling unattended monitoring in remote or mobile applications
• Standardized isokinetic sampling probe and optional temperature/humidity sensor integration for environmental parameter correlation
• Automatic cumulative count logging per channel with time-stamped records stored in non-volatile memory

Sample Compatibility & Compliance

The ZR-1630 is validated for use with ambient air, compressed gases (oil-free), and filtered HVAC supply streams. It is not intended for corrosive, explosive, or high-humidity (>80% RH) environments without external conditioning. Its metrological performance adheres to national verification protocols defined in JJF 1190–2008 (Calibration Specification for Airborne Particle Counters) and functional evaluation criteria outlined in GB/T 6167–2007 (Performance Test Methods for Airborne Particle Counters). While not certified to ISO 21501-4 or IEC 61508, the instrument meets baseline requirements for routine cleanroom monitoring under ISO 14644-1 Class 5–8 environments and supports data integrity practices aligned with GLP and pharmaceutical facility QA/QC workflows.

Software & Data Management

Data acquisition and reporting are managed locally via the embedded firmware interface. All measurement sessions—including date/time stamps, location tags (manually entered), channel-specific counts, and environmental parameters—are stored in CSV-compatible format on internal memory or exported directly to USB flash drives. No cloud connectivity or proprietary desktop software is required. For auditability, each record includes instrument ID, calibration due date (user-configurable), and operator notes. Thermal printer output provides hard-copy documentation suitable for batch release records or regulatory inspections. The system supports basic statistical functions (e.g., average, max/min, standard deviation across sequential samples) but does not implement FDA 21 CFR Part 11 electronic signature or audit trail features.

Applications

• Cleanroom qualification and routine monitoring per ISO 14644-1 and EU GMP Annex 1
• Air filter efficiency testing (e.g., pre-filters, HEPA, ULPA) using upstream/downstream comparison protocols
• Pharmaceutical manufacturing environment validation (aseptic processing areas, isolators, RABS)
• Biological safety cabinet and laminar flow hood performance verification
• Medical device packaging cleanroom surveillance
• Research laboratory aerosol characterization where portability and rapid setup are critical
• Third-party inspection and certification services requiring traceable, field-deployable instrumentation

FAQ

What particle size ranges does the ZR-1630 detect?
It measures particles from 0.3 µm to 10.0 µm across six fixed-size channels: 0.3, 0.5, 1.0, 3.0, 5.0, and 10.0 µm.
Is the instrument calibrated to international standards?
It complies with Chinese national standards GB/T 6167–2007 and JJF 1190–2008; traceable calibration certificates are issued by accredited domestic labs upon request.
Can it be used in compressed air systems?
Yes—provided the air is oil-free, dry (<40% RH), and pressure-regulated to atmospheric inlet conditions via appropriate conditioning hardware.
Does it support remote data transmission?
No—it lacks Ethernet, Wi-Fi, or Bluetooth interfaces; data transfer is limited to USB export and optional thermal printing.
What is the recommended recalibration interval?
Annual recalibration is advised under normal usage; more frequent verification is required after physical shock, extended storage, or exposure to extreme environmental conditions.
