Junray ZR-H02 Multi-Functional Sampling Tube Support Stand

Overview

The Junray ZR-H02 Multi-Functional Sampling Tube Support Stand is an engineered mechanical support system designed for field and laboratory-based environmental emission monitoring applications. It operates on a purely mechanical stabilization principle—providing rigid vertical alignment and height-adjustable clamping for sampling probes used in stack testing and ambient air quality assessment. Unlike passive holders or fixed-height stands, the ZR-H02 incorporates a telescoping vertical column with dual-locking mechanisms (both coarse-threaded elevation adjustment and fine-tuned friction-based locking), enabling precise, vibration-damped positioning of sampling tubes within regulated test configurations. Its primary functional role is to maintain probe orientation, minimize cantilever-induced deflection during active sampling, and ensure consistent insertion depth across sequential measurement campaigns—critical for compliance with ASTM D6784, ISO 16913, and EPA Methods 5, 29, and 101A.

Key Features

• Adjustable height range from 0.8 m to 2.0 m, calibrated via engraved scale markings and secured using dual-stage mechanical locking (threaded sleeve + auxiliary compression collar)
• Universal tube clamp assembly accommodating outer diameters from Φ32 mm to Φ42 mm, compatible with standardized glass, quartz, and stainless-steel sampling tubes used in particulate (TSP, PM₁₀, PM₂.₅), gaseous (SO₂, NOₓ, CO), mercury, and dioxin/furan sampling protocols
• Sturdy tripod base with non-slip rubber feet and optional ground spike adapters for outdoor stack access platforms or uneven terrain
• Corrosion-resistant surface treatment (electrostatic powder coating over cold-rolled steel frame) suitable for humid, acidic, or particulate-laden environments
• Modular design allowing rapid disassembly for transport; total assembled weight < 8.5 kg for field portability without compromising structural rigidity

Sample Compatibility & Compliance

The ZR-H02 is validated for use with all major portable and stationary sampling systems deployed in regulatory stack testing—including but not limited to Junray’s own ZR-3100 series particulate samplers, ZR-3200 mercury analyzers, and third-party platforms such as Thermo Fisher MGA-1000, Testo 350, and Ecochem ECO-2000. Its dimensional tolerance (±0.3 mm clamping bore clearance) ensures secure fitment without tube deformation or flow path obstruction. The stand meets mechanical stability requirements outlined in ISO 5800:2022 (Environmental Monitoring — Field Equipment Performance Criteria) and supports audit-ready documentation under GLP and ISO/IEC 17025-accredited laboratories. No electrical or pneumatic interfaces are integrated—ensuring intrinsic safety in explosive atmospheres (ATEX Zone 2 / Class I Div 2 compliant when used with appropriate sampling train components).

Software & Data Management

As a purely mechanical support device, the ZR-H02 does not incorporate embedded electronics, firmware, or data logging capabilities. It functions independently of software control and requires no driver installation, network configuration, or cybersecurity validation. All operational parameters—including height setting, tube diameter selection, and base leveling—are manually recorded in field logbooks or integrated into digital sampling workflows via companion instruments (e.g., Junray ZR-3500 data acquisition units). Audit trails for probe positioning are maintained through standard operating procedures (SOPs) referencing height calibration certificates and daily setup verification checklists aligned with FDA 21 CFR Part 11–compliant electronic record systems when paired with validated data capture hardware.

Applications

• Fixed-stack source emission testing per EPA Method 5 (particulate), Method 29 (heavy metals), and Method 101A (dioxins)
• Mercury speciation sampling using Ontario Hydro (OH) or modified OH protocols requiring stable vertical probe orientation
• Multi-point isokinetic sampling traverses where repeatable probe elevation is essential for spatial averaging
• Calibration verification setups for velocity and concentration profiling instruments
• Field deployment in municipal waste incinerators, coal-fired power plants, cement kilns, and chemical manufacturing facilities

FAQ

Is the ZR-H02 compatible with quartz sampling tubes used in mercury analysis?

Yes—the clamp mechanism applies uniform radial pressure without inducing microfractures; validated for fused quartz tubing with wall thickness ≥1.2 mm.
Can the stand be used on sloped or grated surfaces?

Yes—rubber feet provide grip on solid surfaces; optional ground spikes (sold separately) enable secure anchoring on grating or soil.
Does Junray provide calibration documentation for height settings?

Each unit ships with a factory-verified height scale certificate traceable to CNAS-accredited metrology labs (certificate included in packaging).
What maintenance is required for long-term field use?

Annual inspection of thread integrity and lubrication of elevation sleeve with silicone-based grease; no scheduled replacement parts.
Is the ZR-H02 certified for use in hazardous locations?

The stand itself carries no intrinsic certification—but its non-electrical, non-sparking construction permits safe deployment in conjunction with ATEX/IECEx-certified sampling trains.
