Overview
The Kanomax 6710 Air Flow Hood Anemometer is a precision-engineered instrument designed for quantitative volumetric airflow measurement in HVAC commissioning, environmental validation, and facility qualification workflows. It operates on the principle of integrated pitot-static pressure differential sensing across a calibrated hood face, combined with simultaneous temperature and relative humidity acquisition. The device computes volumetric flow (m³/h) by integrating velocity profiles across the hood’s cross-sectional area while applying real-time backpressure compensation—critical for maintaining accuracy under variable duct static pressure conditions. Its modular hood system supports rapid adaptation to diverse grille, diffuser, and terminal unit geometries, making it suitable for ISO 14644 cleanroom certification, ASHRAE 111 field testing, and GMP-compliant air handling system verification.
Key Features
- Integrated tri-parameter measurement: simultaneous real-time capture of airflow (m³/h), ambient temperature (0–60 °C), and relative humidity (0–100 %RH)
- Auto-rotating 3.5-inch full-color LCD display enables ergonomic viewing at any orientation, including overhead or recessed installations
- Backpressure compensation algorithm corrects for flow resistance introduced by filter loading or duct configuration, ensuring traceable accuracy per ISO 17025–accredited calibration protocols
- Dual power operation: 4 × AA alkaline batteries (typical 9-hour runtime) or external DC 5 V supply for extended stationary use
- Robust mechanical architecture with lightweight magnesium alloy housing (~3.5 kg) and IP54-rated ingress protection for field durability
- Transparent viewing window on hood body allows visual alignment verification without interrupting measurement
- Onboard clock, battery-level indicator, and intuitive menu navigation support GLP-compliant documentation practices
Sample Compatibility & Compliance
The 6710 accommodates standardized and custom hood configurations—including 610 × 610 mm (standard), 915 × 915 mm, and 1220 × 1220 mm variants—to match common diffuser footprints in laboratories, pharmaceutical manufacturing suites, and hospital isolation rooms. All hood sizes are pre-calibrated against NIST-traceable reference standards and conform to ANSI/ASHRAE Standard 111–2013 for airflow measurement uncertainty. The instrument meets IEC 61000-4 electromagnetic compatibility requirements and is certified for use in non-hazardous environments per CE and RoHS directives. Its measurement uncertainty budget (±3% of reading ±10 m³/h) satisfies regulatory expectations for HVAC balancing under FDA Guidance for Industry: Process Validation (2011) and EU Annex 1 (2022).
Software & Data Management
Data acquired by the 6710 is stored locally in non-volatile memory (3,000 measurement records with timestamp, location ID, and operator tag). USB connectivity enables direct transfer to Windows-based analysis software provided with the system, supporting CSV export for integration into LIMS or electronic batch record (EBR) platforms. RS-232 serial output permits real-time printing via optional thermal micro-printer—ideal for audit-ready hardcopy generation during cleanroom smoke studies or filter leak tests. Audit trail functionality includes user login tracking, parameter change logs, and firmware version stamping, aligning with 21 CFR Part 11 requirements when used with validated software configurations.
Applications
- HVAC system commissioning and re-balancing in pharmaceutical production facilities and biosafety labs
- Cleanroom airflow uniformity and total air change rate validation per ISO 14644-3
- Exhaust hood face velocity verification in chemical fume hood safety assessments (ANSI/AIHA Z9.5)
- Terminal unit (VAV box, HEPA filter module) performance testing during PQ/UQ protocols
- Environmental monitoring during sterile manufacturing process simulations (media fills)
- Energy efficiency audits requiring accurate duct airflow quantification
FAQ
Does the 6710 require annual recalibration?
Yes—Kanomax recommends annual traceable recalibration against primary standards to maintain stated accuracy; certificate includes as-found/as-left data and uncertainty budget.
Can the 6710 measure laminar airflow hoods?
It is not intended for point-velocity mapping in Class II BSCs or laminar flow workbenches; use dedicated anemometers with ≥0.01 m/s resolution for such applications.
Is the backpressure compensation function adjustable by the user?
No—the algorithm is factory-embedded and automatically activates based on differential pressure sensor input; no manual intervention is required or permitted.
Are hood calibration certificates included with optional sizes?
Each individually ordered hood (e.g., 800 × 1100 mm) ships with its own NIST-traceable calibration report specifying effective area and correction factors.
Does the instrument support multi-point averaging across non-uniform grilles?
No—the 6710 performs single-integrated measurement per hood placement; for spatial profiling, use Kanomax’s 6500 series hot-wire anemometer with grid probe accessories.
