Genetec GH-6061E Multi-Function Integrated Sampling Probe for Stack Emission Monitoring

Overview

The Genetec GH-6061E Multi-Function Integrated Sampling Probe is an engineered solution for simultaneous, standardized sampling of particulate matter (PM), moisture content (via dry/wet-bulb thermometry), cooking oil fume, and gaseous pollutants from stationary emission sources—such as industrial boilers, incinerators, kilns, and thermal power plants. Designed in strict accordance with Chinese environmental monitoring standards—including HJ 836-2017 (low-concentration PM determination by gravimetric method), HJ/T 47-1999 (flue gas sampler specifications), and HJ 1077-2019 (oil mist and fume measurement by IR spectrophotometry)—the probe operates on the principle of isokinetic sampling, ensuring representative capture of suspended particles across varying flue gas velocities. Its integrated S-type Pitot tube enables real-time differential pressure measurement for velocity calculation, while dual thermistors (dry-bulb and wet-bulb) support accurate humidity derivation per GB/T 11605-2005. The probe is intended for use exclusively with certified flue gas analyzers and particulate samplers compliant with HJ/T 48-1999.

Key Features

• Integrated multi-sensor architecture: Combines S-type Pitot tube, dual Pt100 temperature sensors (dry/wet-bulb), heated sampling line, and modular nozzle assembly—eliminating inter-device alignment errors and streamlining field setup.
• Titanium alloy sampling nozzle: Precision-machined to ISO-defined isokinetic inlet geometries; permanently bonded to filter media (glass fiber filter cartridge or low-concentration PTFE membrane), minimizing particle bounce, re-entrainment, and seal leakage.
• Active heating system: Uniformly heated to ≥120 °C along the entire probe shaft and nozzle zone, preventing condensation-induced loss of semi-volatile organics and water-soluble aerosols during high-humidity sampling (RH > 90%).
• Modular sampling interface: Supports interchangeable consumables—standard quartz fiber filter tubes (for general PM), low-concentration PTFE membrane cassettes (per HJ 836-2017), and stainless-steel oil fume traps (with IR-detectable collection substrates per HJ 1077-2019).
• Ergonomic design: Lightweight stainless-steel construction (≤3.2 kg), telescopic shaft (0.8–1.5 m), and balanced center-of-gravity enable single-operator handling in confined stack access points.

Sample Compatibility & Compliance

The GH-6061E is validated for sampling matrices defined under China’s Ministry of Ecology and Environment (MEE) regulatory framework. It accommodates particulate mass concentrations ranging from 0.5 mg/m³ (low-concentration mode) to 200 mg/m³ (conventional mode), with demonstrated recovery rates ≥98.5% for PM₁₀ and PM₂.₅ fractions when paired with certified gravimetric balances (Class I, ≤0.01 mg readability). All wet-bulb measurements comply with GB/T 11605-2005 uncertainty requirements (<±1.5% RH at 25 °C). The probe’s structural materials meet HJ/T 48-1999 corrosion resistance criteria for exposure to acidic flue gases (SO₂ ≤ 5,000 mg/m³, NOₓ ≤ 2,000 mg/m³, HCl ≤ 1,000 mg/m³). Calibration traceability is maintained to national metrological standards via annual verification against NIM-certified reference Pitot tubes and thermohygrometers.

Software & Data Management

While the GH-6061E is a hardware-only probe (no embedded electronics), it interfaces seamlessly with Genetec’s GEM-3000 series flue gas analyzers and third-party MEE-certified platforms (e.g., Thermo Fisher 42i, Testo 350, and ENVIRO-TECH EGS-2000). Real-time velocity, temperature, and humidity data are transmitted via analog 4–20 mA outputs or RS-485 Modbus RTU protocol. When used with GLP-compliant data acquisition systems, all sampling parameters—including isokinetic ratio, total sampling volume, and filter blank/tare weights—are automatically logged with time-stamped audit trails satisfying MEE’s QA/QC documentation requirements (HJ 168-2020). Raw data exports support CSV and XML formats compatible with LIMS integration.

Applications

• Regulatory compliance monitoring for coal-fired, biomass, and waste-to-energy facilities under China’s “Blue Sky Protection Campaign” enforcement protocols.
• Low-concentration PM testing in ultra-low-emission (ULE) power plants, where sub-5 mg/m³ particulate limits demand high-fidelity isokinetic capture.
• Restaurant and food-processing sector油烟 (cooking oil fume) audits, meeting local environmental bureau requirements for VOC-bound aerosol quantification.
• Stack testing during Environmental Impact Assessment (EIA) commissioning and periodic performance verification per GB 13223-2011 and GB 18485-2014.
• Method validation studies supporting laboratory accreditation (CNAS-CL01:2018) and cross-border technology transfer projects requiring ISO/IEC 17025-aligned sampling workflows.

FAQ

Is the GH-6061E compatible with non-Chinese flue gas analyzers?
Yes—provided the host instrument supports standard 4–20 mA analog inputs or Modbus RTU communication and meets HJ/T 47-1999 electrical interface specifications.
Does the probe include built-in data logging capability?
No—the GH-6061E is a passive sampling device; data acquisition and storage must be performed by the connected analyzer or external DAQ system.
What maintenance intervals are recommended for the titanium nozzle and heating elements?
Visual inspection before each use; full calibration verification every 100 operational hours or quarterly—whichever occurs first—using certified reference standards.
Can the probe be used for sampling at temperatures exceeding 200 °C?
No—maximum continuous operating temperature is 180 °C; extended exposure above this threshold risks thermistor drift and heater insulation degradation.
Are replacement nozzles and filter holders available as spare parts?
Yes—Genetec supplies OEM-certified titanium nozzles (Φ4/6/8/10 mm), low-concentration PTFE membrane cassettes (100 mm diameter), and quartz fiber filter tubes (40 mm ID), all traceably packaged with batch-specific QC certificates.
