Overview
The Genetec GH-6061C Multi-Function Particulate Sampling Probe is an integrated, field-deployable sampling device engineered for regulatory-compliant isokinetic sampling of particulate matter from fixed emission sources. It operates on the principle of velocity-tracked isokinetic sampling—where gas stream velocity at the probe inlet is matched to the flue gas velocity via real-time differential pressure feedback from the built-in S-type Pitot tube—to ensure representative particle capture across varying duct flow profiles. Designed for use with certified particulate mass analyzers (e.g., gravimetric stack testing systems), the GH-6061C supports three primary sampling modalities: conventional high-concentration particulate sampling using glass fiber filter tubes, low-concentration particulate sampling per HJ 836–2017 using polytetrafluoroethylene (PTFE) membrane filters, and油烟/油雾 (cooking oil mist and industrial oil aerosol) sampling in accordance with HJ 1077–2019. Its heated probe body mitigates condensation-induced particle loss in high-humidity or low-temperature exhaust streams, preserving sample integrity during transit to the collection medium.
Key Features
- Integrated tri-functional design: Combines an S-type Pitot tube for dynamic/static pressure differential measurement, a calibrated Pt100 temperature sensor (±0.5 °C accuracy), and a coaxial sampling gas pathway within a single lightweight stainless-steel housing.
- Modular front-end compatibility: Accepts standardized 47-mm diameter PTFE membrane filters for low-concentration particulate analysis (HJ 836–2017), quartz fiber filter tubes for traditional gravimetric determination (HJ/T 48–1999), and hydrophobic mesh-supported collection substrates for oil mist capture (HJ 1077–2019).
- Titanium alloy sampling nozzle: Precision-machined with tight tolerance (±0.1 mm) internal diameter control; permanently bonded to the filter support structure to eliminate dead-volume gaps and minimize particle bounce or re-entrainment.
- Active heating system: Uniform axial heating (up to 180 °C, adjustable in 5 °C increments) with PID-controlled thermal regulation ensures dew point suppression throughout the entire sampling train—including nozzle, filter holder, and inner probe wall—reducing moisture-related bias in mass recovery.
- Ergonomic field deployment: Total probe weight < 2.8 kg; telescoping handle (adjustable from 0.8 m to 1.5 m); IP54-rated electronics enclosure; and quick-disconnect pneumatic fittings compliant with ISO 8573-1 Class 3 compressed air standards.
Sample Compatibility & Compliance
The GH-6061C meets the mechanical and metrological requirements of multiple Chinese environmental monitoring standards, serving as a validated component within full-stack particulate measurement systems. It is explicitly referenced in method validation protocols for HJ 836–2017 (low-concentration particulate gravimetry), HJ/T 48–1999 (performance specifications for particulate samplers), and HJ 1077–2019 (infrared spectrophotometric quantification of cooking oil aerosols). While not certified to ISO 16940 or EN 13284-1 by default, its dimensional tolerances, material traceability (Ti-6Al-4V nozzle, 316L SS body), and documented thermal uniformity profile support third-party verification for international GLP-aligned laboratories. All calibration certificates include NIST-traceable pressure and temperature references.
Software & Data Management
The GH-6061C operates as a hardware subsystem—not a standalone instrument—and interfaces exclusively with host particulate analyzers equipped with analog/digital I/O modules (4–20 mA pressure output, RS-485 Modbus RTU for temperature telemetry). No embedded firmware or proprietary software is included. However, Genetec provides a documented API reference guide (v2.1) outlining signal mapping, error code definitions (e.g., E07 = heater open-circuit, E12 = Pitot blockage detection), and timestamp-synchronized data logging protocols compatible with LabVIEW, MATLAB, and industry-standard SCADA platforms. Audit trails generated during field use comply with basic ALCOA+ principles when paired with validated host systems supporting 21 CFR Part 11 electronic signature and change-control functions.
Applications
- Regulatory stack testing for thermal power plants, cement kilns, and waste incinerators under China’s GB 13223 and GB 18485 emission limits.
- Source apportionment studies requiring parallel low-concentration PM₂.₅ and oil mist quantification in food processing exhaust and metalworking fluid mist environments.
- Method development and inter-laboratory comparison exercises targeting ISO/IEC 17025 accreditation for particulate mass concentration measurement.
- Performance verification of electrostatic precipitators (ESPs), fabric filters, and wet scrubbers where isokinetic sampling fidelity directly impacts removal efficiency calculations.
FAQ
Is the GH-6061C compatible with non-Chinese analyzers such as Testo 350 or Thermo Fisher pDR series?
Yes—provided the host analyzer supports 4–20 mA analog input for Pitot differential pressure and PT100 resistance reading via standard 3-wire configuration. Pinout diagrams and scaling coefficients are supplied in the technical appendix.
Does the titanium nozzle require periodic recalibration?
No—dimensional stability is certified for 5,000 operational cycles; however, visual inspection for erosion or deposition buildup is recommended before each high-load campaign.
Can the probe be used for volatile organic compound (VOC) sampling?
No—it lacks sorbent tube integration or cryogenic trapping capability; it is strictly intended for particulate-phase collection.
What maintenance intervals are specified for the heating element and thermal insulation?
Heater resistance verification every 200 operating hours; ceramic fiber insulation inspection for compression damage annually or after exposure to >200 °C flue gas surges.
Is third-party certification available for export to EU or US markets?
Genetec supports CE marking documentation packages (including EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU) upon request; FDA 510(k) clearance is not applicable as the probe is classified as an accessory, not a medical device.
