Overview
The Junray ZR-D09W Coupled Low-Concentration Multipurpose Flue Dust Sampling Probe is a precision-engineered sampling interface designed for regulatory-compliant measurement of low-concentration particulate matter (PM) in fixed emission sources. It operates on the gravimetric principle per HJ 836–2017 and integrates seamlessly with certified flue gas particulate samplers to ensure representative isokinetic sampling under challenging field conditions—including high humidity (>90% RH), low flue gas temperatures (<50 °C), and variable flow regimes. Unlike conventional probes, the ZR-D09W employs a fully coupled, two-segment modular architecture that unifies pneumatic, thermal, and electrical pathways in a single mechanical interface—eliminating external tubing, reducing leak risk, and minimizing thermal lag. Its heated front section maintains filter media at a stable, user-defined temperature (typically 110–120 °C) to prevent condensation-induced particle loss, while the integrated dry-wet bulb hygrometer complies with GB/T 16157–1996 for real-time moisture content determination.
Key Features
- Uniform front-end heating system with PID-controlled temperature regulation (±1 °C stability) across the entire sampling head assembly
- Modular Pitot tube assembly—field-replaceable without tools, enabling rapid calibration verification and contamination mitigation
- Two-part quick-coupling design: ergonomic handgrip and probe body interlock via precision-machined bayonet interface, achieving simultaneous gas-tight sealing and electrical continuity in <3 seconds
- Multi-format filter compatibility: supports 47-mm quartz fiber filters, standard glass fiber filter cartridges (Φ47 mm × 60 mm), and specialized oil mist filters per HJ 1077–2019
- Structural integrity ensured by aerospace-grade titanium alloy (Grade 2) or electropolished 316L stainless steel construction—resistant to chloride-induced pitting and acidic condensates (pH ≥ 2.0)
- Real-time angular deviation monitoring: built-in dual-axis inclinometer triggers audible/visual alert when sampling nozzle orientation exceeds ±5° from isokinetic alignment
- Pre-installed ISO/IEC 15693-compatible RFID tag for automated instrument lifecycle tracking, calibration history logging, and GLP-compliant inventory management
- Dedicated expansion port for optional wireless process module (supports RS-485 Modbus RTU or LoRaWAN) to transmit dynamic pressure, static pressure, flue gas temperature, and calculated velocity directly to host sampler
Sample Compatibility & Compliance
The ZR-D09W is validated for use with EPA Method 5, ISO 9096, and Chinese national standards including HJ 836–2017 (low-concentration PM gravimetry), HJ 1077–2019 (oil mist/oil fume quantification), GB 18483–2001 (catering emissions), and HJ/T 48–1999 (sampler performance criteria). Its one-piece sampling head—comprising inlet nozzle, L-shaped sampling tube, filter support grid, aluminum foil gasket, and pre-weighed membrane—is certified for total mass uncertainty ≤ ±0.05 mg (per ASTM D7520–19 guidance). The probe meets electromagnetic compatibility requirements per GB/T 18268.1–2010 and is rated IP54 for field deployment in industrial environments with airborne particulates and intermittent water exposure.
Software & Data Management
When paired with Junray’s ZR-Series data acquisition platforms (e.g., ZR-3100, ZR-3200), the ZR-D09W enables full audit trail generation compliant with FDA 21 CFR Part 11 Annex 11 requirements. All sensor readings—including temperature setpoint, actual heater temperature, inclination angle, and (if equipped) wireless process data—are timestamped, digitally signed, and stored with immutable metadata (operator ID, location GPS coordinates, calibration certificate ID). The embedded RFID tag interfaces with Junray’s Instrument Lifecycle Management (ILM) software, supporting automated checkout/check-in, preventive maintenance scheduling, and traceability to NIM-certified reference standards.
Applications
The ZR-D09W serves as a primary sampling interface across environmental monitoring, industrial hygiene, and regulatory enforcement workflows. Typical applications include: continuous compliance testing at coal-fired power plants (ESP/FF outlet ducts), PM2.5 characterization in cement kiln preheater stacks, oil mist monitoring in cold rolling mills, cooking oil aerosol assessment in commercial kitchens, and fugitive emission screening in chemical synthesis reactors. Its modular scalability supports extended-length configurations (up to 5 m) for large-diameter stacks, while the heated filter support ensures accurate mass recovery in biomass boiler exhausts where semi-volatile organic compounds (SVOCs) would otherwise re-condense.
FAQ
Does the ZR-D09W require external power for heating during operation?
Yes—it draws regulated DC power (24 V ±10%) from the connected sampling host unit; no separate power supply is needed.
Can the probe be used for isokinetic sampling at velocities below 3 m/s?
Yes—its low-inertia Pitot tube and integrated differential pressure transducer enable stable isokinetic control down to 1.5 m/s per HJ 836–2017 Annex B.
Is the dry-wet bulb hygrometer calibrated traceable to national standards?
Yes—factory calibration is performed against NIM-certified dew point standards, with certificate of calibration included.
What filter media are supplied with the probe?
None—the ZR-D09W is media-agnostic; users select filters based on matrix (e.g., quartz for OC/EC analysis, PTFE for hydrophobic aerosols) per method requirements.
How is angular misalignment detected and reported?
An onboard MEMS-based inclinometer continuously monitors pitch and yaw; deviations >±5° trigger LED indicator and data flagging in the host system log file.
