Overview
The Kanomax 6710 Air Flow Hood is a portable, integrated environmental measurement instrument engineered for precise, traceable air volume quantification in HVAC commissioning, facility validation, and indoor air quality (IAQ) assessments. It operates on the principle of volumetric flow measurement via calibrated hood capture—where airflow entering the hood is measured using an internal multi-point velocity sensor array, corrected in real time for static pressure differential (backpressure compensation), and converted to volumetric flow rate (m³/h) using the hood’s effective cross-sectional area. Simultaneously, it acquires ambient temperature (±0.5 °C) and relative humidity (±3 %RH within 10–90 %RH) using factory-calibrated NTC thermistors and capacitive RH sensors. Designed for compliance-critical environments—including cleanrooms, laboratories, hospitals, and pharmaceutical manufacturing suites—the 6710+ meets the functional requirements of ISO 14644-3, ISO 14644-4, ASHRAE Standard 111, and EU GMP Annex 1 for air change rate verification and terminal unit balancing.
Key Features
- Real-time backpressure compensation algorithm ensures stable readings across variable duct static pressures, eliminating manual correction factors.
- Auto-rotating 3.5-inch color LCD display enables ergonomic viewing at up to 30° tilt—critical during overhead or confined-space measurements.
- Integrated triple-sensor architecture simultaneously captures air volume, temperature, and humidity without requiring external probes or secondary instruments.
- Onboard storage capacity of 3,000 measurement records includes timestamp, hood ID, flow value, temperature, RH, and operator notes—each tagged with unique session metadata.
- Transparent polycarbonate viewing window allows visual confirmation of grille alignment and airflow uniformity during hood placement.
- Dual-power operation supports extended field use: 4 × AA alkaline batteries (≥9 h continuous operation) or regulated DC 5 V input for benchtop or fixed-location applications.
- Standard 610 × 610 mm hood included; 10 additional optional hood sizes accommodate diverse diffuser geometries—from compact ceiling grilles to large displacement ventilation panels.
Sample Compatibility & Compliance
The 6710+ is validated for use with supply and exhaust air terminals compliant with EN 12599, ISO 16813, and ASHRAE Guideline 12. Its measurement uncertainty profile (±3% of reading ±10 m³/h) is traceable to JCSS-accredited calibration standards in Japan. The device satisfies data integrity requirements under FDA 21 CFR Part 11 when used with Kanomax-provided software (v3.2+), supporting electronic signatures, audit trails, and export-controlled file formats (CSV, PDF). All firmware and sensor modules undergo periodic recalibration per ISO/IEC 17025–accredited procedures. Relative humidity accuracy is specified per IEC 60751 Class B tolerances; temperature sensing conforms to ASTM E2234 for HVAC airflow instrumentation.
Software & Data Management
Kanomax AirFlow Manager software (Windows-compatible, USB/RS-232 supported) enables full post-processing of stored datasets: statistical analysis (mean, min/max, standard deviation), trend plotting, report generation (PDF/Excel), and batch export with customizable templates aligned to ISO 14644-3 Annex D reporting structures. Audit trail functionality logs all user actions—including data deletion, parameter modification, and calibration events—with timestamps and operator IDs. Exported reports include embedded device serial number, firmware version, calibration due date, and measurement uncertainty statements—facilitating GLP/GMP documentation workflows. Raw data files are cryptographically hashed to ensure immutability prior to archival.
Applications
- HVAC system commissioning and TAB (Testing, Adjusting, Balancing) in commercial and healthcare facilities.
- Cleanroom classification (ISO 14644-1) and requalification through air change rate (ACH) and supply/exhaust balance verification.
- Pharmaceutical isolator and RABS performance qualification per EU GMP Annex 1 Section 4.37.
- University and industrial laboratory ventilation safety audits per ANSI/AIHA Z9.5.
- Energy efficiency assessments including fan power optimization and duct leakage estimation.
- Post-renovation IAQ verification following ASHRAE 62.1–2022 ventilation rate procedure.
FAQ
Does the 6710+ require annual recalibration?
Yes. Kanomax recommends annual recalibration against NIST-traceable standards to maintain stated accuracy; calibration certificates include uncertainty budgets per ISO/IEC 17025.
Can the device measure laminar flow hoods or biosafety cabinets?
It is not designed for ultra-low-velocity laminar applications (<0.15 m/s); however, it is suitable for measuring total exhaust flow from Class II BSCs when used with appropriately sized hoods (e.g., 915×915 mm or 1220×1220 mm).
Is the USB interface compatible with macOS or Linux systems?
The native Kanomax AirFlow Manager software is Windows-only; however, raw CSV exports can be imported into cross-platform analytics tools (e.g., Python Pandas, MATLAB, R).
What is the maximum allowable static pressure for accurate measurement?
The backpressure compensation system is validated for differential pressures up to ±150 Pa; beyond this range, measurement drift may exceed ±5% without manual correction.
Are optional hoods supplied with individual calibration certificates?
Yes—each optional hood size undergoes independent area verification and is delivered with a certificate stating effective open area (±0.3%) and associated uncertainty.
