Overview
The Junray ZR-1630 is a handheld optical particle counter engineered for precise, real-time airborne particulate monitoring in controlled environments. It operates on the principle of single-particle light scattering—where particles suspended in an air stream pass through a focused laser beam, generating scattered light pulses proportional to their size. These pulses are detected by a high-sensitivity photodetector and classified into six user-selectable size channels spanning 0.3 µm to 10.0 µm. Designed to meet the metrological requirements of cleanroom validation and routine environmental monitoring, the ZR-1630 delivers calibrated particle concentration data (particles per cubic meter) at a nominal volumetric flow rate of 28.3 L/min—aligned with ISO 21501-4 and USP <788> sampling conventions. Its integrated vacuum pump, precision mass-flow control circuitry, and HEPA-filtered exhaust ensure stable aspiration and operator/environmental safety during field or in-situ measurements.
Key Features
- Optical detection system optimized for 0.3–10.0 µm particle sizing with six simultaneous counting channels
- Integrated diaphragm vacuum pump enabling consistent 28.3 L/min sampling flow (±2% accuracy)
- Onboard HEPA filter (≥99.97% @ 0.3 µm) for safe exhaust air treatment
- Self-cleaning time ≤ 5 minutes—verified per GB/T 6167-2007
- 7-inch capacitive touch display with Chinese/English bilingual GUI and graphical real-time histogram rendering
- Internal rechargeable lithium-ion battery supporting ≥4 hours of continuous operation
- Standard isokinetic sampling probe and integrated temperature/humidity sensor (±0.5 °C, ±3% RH typical)
- Automatic cumulative count logging per channel with timestamp and location tagging (optional GPS module)
Sample Compatibility & Compliance
The ZR-1630 is validated for use with ambient air, compressed gases (with optional desiccant/dew-point conditioning), and laminar airflow streams in ISO Class 3–8 cleanrooms (per ISO 14644-1). It complies with national metrological standards GB/T 6167-2007 (Performance Test Methods for Airborne Particle Counters) and JJF 1190-2008 (Calibration Specification for Airborne Particle Counters). While not certified to IEC 61000-4 electromagnetic immunity suites or ATEX/IECEx for hazardous areas, its design conforms to general laboratory safety practices under GB 4793.1. Data integrity is supported via audit-trail-capable internal storage and tamper-evident file export—facilitating GLP-aligned documentation in pharmaceutical QC labs and medical device manufacturing facilities.
Software & Data Management
Data acquisition and reporting are managed through embedded firmware supporting CSV export via USB flash drive and direct thermal printing (via optional RS-232 or Bluetooth printer interface). The instrument stores up to 10,000 sample records internally, each containing channel-specific cumulative counts, flow rate, temperature, humidity, sampling duration, and operator ID. Exported files include metadata headers compliant with ASTM E29-23 formatting conventions for traceability. No proprietary desktop software is required; raw CSV outputs integrate natively with LIMS platforms, Microsoft Excel, or Python-based analysis pipelines (e.g., Pandas + Matplotlib for trend visualization). Firmware updates are performed offline via FAT32-formatted USB media—ensuring regulatory compliance in airlock-controlled environments where network connectivity is restricted.
Applications
- ISO 14644-1 cleanroom classification and re-certification (point-of-use mapping of Class 5–8 environments)
- In-process verification of HEPA/ULPA filter integrity and leak testing (in conjunction with aerosol challenge generators)
- Environmental monitoring in aseptic processing suites, isolators, and RABS per EU GMP Annex 1 and FDA Guidance for Industry
- Filter media efficiency evaluation per ISO 16890 and EN 779 test protocols
- Occupational health assessments in semiconductor fabrication, biotech clean labs, and hospital pharmacy compounding areas
- Validation of biosafety cabinet performance (NSF/ANSI 49) and laminar flow workstations
FAQ
What calibration standards does the ZR-1630 support?
It is factory-calibrated using NIST-traceable PSL (polystyrene latex) spheres per JJF 1190-2008. Users may perform field verification with ISO 21501-4-compliant reference aerosols.
Can the instrument be used for compressed air monitoring?
Yes—with appropriate pressure regulation, drying, and isokinetic sampling accessories to prevent condensation-induced measurement bias.
Is the data export format compatible with FDA 21 CFR Part 11 requirements?
Raw CSV exports contain immutable timestamps and operator identifiers; full Part 11 compliance requires integration with a validated LIMS or ELN platform that enforces electronic signatures and audit trails.
How is flow stability maintained across varying inlet pressures?
A closed-loop PID-controlled mass flow controller dynamically adjusts pump speed to sustain 28.3 L/min within ±2% tolerance, even with filter loading or minor backpressure fluctuations.
Does the unit support remote monitoring or network connectivity?
No built-in Wi-Fi or Ethernet; however, periodic USB data retrieval enables centralized database ingestion in air quality management systems.
