Overview
The Kanomax 6715 Multi-Parameter Air Flow Hood is an integrated, handheld environmental measurement instrument engineered for precise, on-site quantification of volumetric air flow in HVAC ducts, grilles, diffusers, and terminal devices. It operates on the principle of averaging velocity profiles across a defined cross-sectional area—using either a pitot-static tube or a multi-point thermal anemometer matrix—then applying real-time backpressure compensation to correct for system resistance effects inherent in hood-based measurements. This dual-sensor architecture ensures traceable, repeatable results compliant with ASHRAE Standard 111, ISO 16813, and ANSI/ASHRAE Guideline 12–2020 for HVAC commissioning and indoor air quality (IAQ) validation. Designed for field engineers, facility managers, and third-party commissioning agents, the 6715 delivers simultaneous measurement of air flow (m³/h), air velocity (m/s), differential pressure (Pa), ambient temperature (°C), and relative humidity (%RH)—all within a single, ergonomic housing.
Key Features
- Simultaneous five-parameter acquisition: air flow, velocity, differential pressure, temperature, and humidity—eliminating need for multiple instruments during HVAC balancing.
- Backpressure compensation algorithm dynamically adjusts flow calculation based on measured static pressure differential across the hood face, reducing systematic error in high-resistance installations (e.g., HEPA-filtered terminals).
- 3.5-inch full-color LCD with manual 30° tilt mechanism enables clear data visibility in confined ceiling spaces or angled mounting positions.
- Bluetooth 4.2 LE connectivity supports wireless configuration, real-time data streaming, and remote firmware updates via the official Kanomax Mobile App (iOS and Android).
- Integrated 8,000-set internal memory with timestamp, location tagging (via paired smartphone GPS), and auto-sequenced file naming for audit-ready data logging.
- Dual-sensor flexibility: interchangeable pitot tube (0.15–40 m/s) and thermal matrix probe (0.15–15 m/s) allow optimization for high-velocity ducts or low-velocity diffuser applications.
- Transparent polycarbonate viewing window permits visual confirmation of airflow uniformity and particulate presence without removing the hood from the test point.
- Comprehensive I/O: USB 2.0 (for PC synchronization and firmware), RS232 serial port (for legacy printers), and optional Bluetooth printer support ensure compatibility with existing QA/QC workflows.
Sample Compatibility & Compliance
The Kanomax 6715 accommodates standard and custom hood sizes—including 610×610 mm (standard), 305×1220 mm, 800×1100 mm, and 1220×1220 mm—enabling accurate measurement across diverse terminal types: VAV boxes, laminar flow hoods, cleanroom FFUs, supply/exhaust grilles, and biological safety cabinets. Its operating range (40–4300 m³/h) covers typical commercial HVAC applications while maintaining ±3% ±10 m³/h accuracy per ISO 5167-derived calibration protocols. All sensors are factory-calibrated against NIST-traceable standards; certificate of calibration (including uncertainty budgets) is supplied with each unit. The instrument meets CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and complies with RoHS 2011/65/EU. While not certified for intrinsic safety, it is rated for use in non-hazardous environments per IEC 60529 IP20.
Software & Data Management
Data export and reporting are supported through Kanomax’s proprietary PC software (Windows 10/11 compatible), which provides configurable report templates (PDF/CSV/XLSX), statistical summaries (mean, SD, CV%), pass/fail thresholds per ASHRAE 111 Annex B, and graphical trend overlays. The mobile app enables live monitoring, instant annotation, photo capture synchronized with readings, and cloud backup via secure HTTPS endpoints. Audit trails—including user login history, parameter changes, and data export timestamps—are maintained locally and exported with reports to satisfy GLP and ISO/IEC 17025 documentation requirements. Firmware updates preserve historical calibration coefficients and do not reset device configuration or stored data.
Applications
- HVAC system commissioning and TAB (Testing, Adjusting, Balancing) per NEBB Procedural Standards.
- Annual IAQ audits in hospitals, laboratories, pharmaceutical cleanrooms (ISO 14644-3), and data centers.
- Verification of exhaust hood face velocity and containment performance (e.g., fume hoods per ANSI/AIHA Z9.5).
- Validation of air change rates in critical environments including operating rooms (ASHRAE 170) and isolation rooms.
- Energy efficiency assessments—quantifying actual vs. design airflow to identify duct leakage or damper misalignment.
- Preventive maintenance scheduling based on long-term flow drift trends logged over multiple seasons.
FAQ
Is the Kanomax 6715 still in production?
No—the 6715 has been formally discontinued and superseded by the Kanomax 6720, which features a 4.3-inch touchscreen, enhanced Bluetooth stack, extended battery life (14 h), and expanded data capacity (10,000 sets via app). Units currently in service remain fully supported with spare parts and calibration services.
Does the 6715 support FDA 21 CFR Part 11 compliance?
The device itself does not include electronic signature or audit trail functionality required for full Part 11 compliance; however, when used with validated Kanomax PC software and documented SOPs, it may be incorporated into Part 11–compliant workflows for pharmaceutical HVAC qualification.
Can the 6715 measure airflow in round ducts?
It is optimized for rectangular or square openings; round duct measurements require a custom adapter plate or transition hood to ensure uniform velocity sampling and minimize edge turbulence effects.
What is the recommended recalibration interval?
Kanomax recommends annual recalibration against accredited standards; more frequent verification (e.g., pre- and post-job checks using a known reference flow source) is advised for critical applications.
Are replacement hoods and matrices available as spares?
Yes—standard and extended-size hoods, thermal matrix probes, pitot tubes, and calibration kits are stocked globally through authorized Kanomax distributors and service centers.
