Kanomax 6750 Portable Air Flow Hood Anemometer

Overview

The Kanomax 6750 Portable Air Flow Hood Anemometer is an engineered solution for precise, field-deployable volumetric air flow measurement in HVAC systems. Utilizing a calibrated pitot-static pressure sensing principle integrated with a low-turbulence, high-efficiency flow hood, the instrument measures total volumetric flow (m³/h or CFM) at supply and exhaust registers, diffusers, grilles, and terminal units. Its design conforms to fundamental airflow measurement standards—particularly ASHRAE Guideline 111 (Methods of Testing for Rating Air Terminal Units) and ISO 16813 (HVAC performance testing)—ensuring traceable, repeatable results under real-world ductwork and room conditions. Unlike handheld anemometers requiring multi-point traverse averaging, the 6750 captures integrated flow across its 355 mm × 355 mm aperture in a single placement, minimizing operator-induced variability and eliminating spatial interpolation errors.

Key Features

• True dual-parameter real-time display: Simultaneous readout of volumetric flow (m³/h or CFM) and ambient temperature (°C) on a 160 × 80 mm full-color TFT LCD with intuitive icon-based navigation.
• Optical alignment window: Transparent front panel enables direct visual verification of hood-to-register contact integrity—critical for maintaining seal fidelity and avoiding underestimation due to air bypass.
• Robust mechanical architecture: Fiberglass-reinforced support frame ensures dimensional stability during repeated handling and maintains consistent hood geometry across thermal gradients (0–50 °C operating range).
• Integrated data governance: Onboard storage for up to 6,000 measurement records with timestamp, flow value, temperature, and unit metadata—fully compliant with GLP-aligned field documentation workflows.
• Wireless and wired connectivity: Bluetooth 4.0 interface supports secure pairing with iOS/Android tablets running Kanomax’s dedicated configuration app; USB port enables direct CSV export for QA/QC audit trails and integration into CMMS platforms.

Sample Compatibility & Compliance

The 6750 is validated for use with standard rectangular and square supply/exhaust openings (355 mm × 355 mm nominal). Optional accessory hoods (sold separately) extend compatibility to non-standard register sizes while preserving calibration integrity through area-ratio compensation algorithms embedded in firmware. The device meets electromagnetic compatibility requirements per IEC 61326-1 (industrial environments) and is constructed to IP42 ingress protection standards. Its measurement methodology aligns with ASHRAE 111 Annex B (flow hood accuracy validation), ISO 12731 (air velocity and volume flow rate determination), and EN 12599 (commissioning of ventilation systems). Temperature sensor calibration is NIST-traceable, and flow accuracy specifications are verified per manufacturer’s ISO/IEC 17025-accredited test protocol.

Software & Data Management

Kanomax provides free firmware-upgradable desktop and mobile applications supporting configuration, real-time monitoring, and post-processing. All stored data include UTC timestamps, battery status, measurement mode flags, and auto-applied unit conversions. Audit-ready reports can be generated with customizable headers (project ID, technician name, location tag) and exported in CSV or PDF formats. Bluetooth transmission employs AES-128 encryption; local USB transfer requires no driver installation on Windows/macOS/Linux. Data logs comply with FDA 21 CFR Part 11 requirements when used with Kanomax’s optional electronic signature module and password-protected user roles.

Applications

• HVAC system commissioning and balancing per TAB (Testing, Adjusting, and Balancing) protocols
• Annual functional testing of VAV boxes, fan coil units, and rooftop units
• ISO Class 5–8 cleanroom air change rate verification (per ISO 14644-3)
• Energy audit baseline measurements for ASHRAE Level I and II assessments
• Post-renovation ventilation validation in healthcare facilities (per FGI Guidelines and HTM 03-01)
• Educational laboratory instruction in building science and indoor environmental quality

FAQ

What standards does the Kanomax 6750 reference for flow accuracy verification?

It follows ASHRAE Guideline 111 Annex B procedures and is factory-calibrated against NIST-traceable primary standards using laminar flow elements per ISO 17025 requirements.
Can the 6750 measure airflow in round ducts?

Yes—when paired with optional circular adapter hoods and configured via software for diameter-specific area correction.
Is the internal memory data retained during battery replacement?

Yes. Non-volatile flash memory preserves all 6,000 records even with complete power loss.
Does the device support custom calibration for non-standard hood sizes?

No—only certified Kanomax accessory hoods with pre-programmed area coefficients are supported to maintain stated accuracy.
How is temperature compensation applied during flow calculation?

Real-time ambient temperature readings adjust density-dependent flow coefficients in accordance with ISO 5167-2:2003 derived algorithms.
