Overview
The Kanomax 6720 Advanced Multi-Parameter Air Flow Hood is a next-generation handheld instrument engineered for high-accuracy, real-time quantification of volumetric air flow in HVAC ducts, terminal devices (e.g., VAV boxes, diffusers, grilles), and cleanroom supply/exhaust systems. Built upon the legacy of the discontinued 6715 platform, the 6720 integrates simultaneous measurement of air flow, velocity, differential pressure, ambient temperature, and relative humidity—enabling comprehensive environmental balancing and performance verification without external sensors or secondary instruments. Its core airflow sensing architecture employs a calibrated multi-point velocity matrix (with optional pitot tube integration) coupled with dynamic backpressure compensation, ensuring stable readings across variable static pressure conditions typical in ducted systems. The device conforms to industry-standard test methodologies defined in ASHRAE Guideline 111-2013 (Instrumentation for Measuring Air Flow Rates), ISO 14644-3:2019 (Cleanrooms—Testing), and ISO 14644-4:2022 (Design and Construction), making it suitable for GLP-compliant commissioning, validation, and routine QA/QC audits.
Key Features
- Simultaneous five-parameter measurement: air flow (m³/h), velocity (0.15–40 m/s), differential pressure (–2500 to +2500 Pa), temperature (0–50 °C), and humidity (0–100% RH)
- 4.3-inch full-color resistive touchscreen with intuitive icon-driven UI and manual 30° tilt adjustment for ergonomic viewing at varied angles
- Integrated backpressure compensation algorithm that dynamically corrects flow readings under non-ideal static pressure conditions
- Configurable K-factor calibration for precise adaptation to diverse hood geometries and airflow profiles
- Bluetooth 5.0 wireless communication enabling remote control, live data streaming, and firmware updates via the official Kanomax AirFlow Manager mobile application (iOS/Android)
- Internal storage capacity of 8,000 measurement records with timestamp, location tag, and parameter metadata; extended capacity up to 10,000 entries via synchronized app storage
- Dual power operation: 4 × AA alkaline batteries (rated for ~14 hours continuous use) or external DC 5 V input with auto-switching
- Modular hood system supporting 10 standardized sizes—from compact 305 × 1220 mm to large-area 1400 × 800 mm—with quick-release mounting and optical alignment window for visual confirmation of sealing integrity
Sample Compatibility & Compliance
The 6720 is validated for use with standard rectangular and square air terminals, including ceiling diffusers, sidewall grilles, and laminar flow hoods. Its velocity matrix sensor array ensures representative spatial averaging across turbulent and transitional flow regimes common in low-velocity (10 m/s) applications. Optional pitot tube and flexible air velocity matrix configurations extend compatibility to irregularly shaped openings and high-static-pressure environments. Instrument design and metrological traceability align with international regulatory expectations: data logging includes immutable timestamps, operator ID fields, and audit-ready export formats (CSV, PDF). While not FDA 21 CFR Part 11–certified out-of-the-box, the device supports ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) when used with controlled procedures and validated software workflows—making it appropriate for GMP-aligned cleanroom qualification per ISO 14644-1 and EU Annex 1.
Software & Data Management
The Kanomax AirFlow Manager mobile application provides full instrument configuration, real-time graphing, report generation, and cloud synchronization. All measurements are tagged with GPS coordinates (when enabled), date/time, user ID, and hood identification number. Export options include CSV for statistical analysis in Excel or Minitab, and PDF reports compliant with ISO/IEC 17025 documentation requirements. USB-C and RS-232 interfaces support wired data transfer and direct thermal printing using optional Kanomax-certified printers. Firmware updates are delivered through the app or desktop utility, with version history and changelogs maintained for quality system traceability. Data integrity safeguards include automatic checksum validation during transmission and write-protection for archived records.
Applications
- HVAC system commissioning and TAB (Testing, Adjusting, Balancing) per NEBB and AABC standards
- Cleanroom air change rate verification and ISO Class compliance testing
- Pharmaceutical facility environmental monitoring (Grade A–D zones) and HVAC requalification
- University and industrial laboratory ventilation safety assessments (e.g., fume hood face velocity, exhaust balance)
- Energy efficiency audits and retrocommissioning of aging building systems
- Validation of HEPA filter integrity and airflow uniformity in laminar flow workstations
FAQ
What distinguishes the 6720 from the legacy 6715 model?
The 6720 replaces the 6715 with an upgraded 4.3-inch touchscreen interface, enhanced battery life (~14 h), expanded internal memory (8,000 vs. 3,000 records), Bluetooth 5.0 connectivity, and refined backpressure compensation logic—while maintaining backward compatibility with all 6715 accessories and hood sizes.
Is the 6720 suitable for ISO 14644-3 cleanroom certification?
Yes—the instrument meets the accuracy, repeatability, and documentation requirements specified in ISO 14644-3:2019 Annex B for air volume flow measurement, provided proper hood selection, sealing technique, and calibration intervals (recommended annually or per manufacturer’s schedule) are observed.
Can the 6720 be used with non-standard hood dimensions?
Yes—custom hood frames may be fabricated to match the 6720’s mounting interface specifications; however, K-factor recalibration using NIST-traceable reference standards is required prior to use for quantitative reporting.
Does the device support automated calibration verification?
No built-in self-calibration function exists; however, the unit includes a dedicated “Cal Check” mode that validates sensor response against known reference inputs, and supports external verification using certified flow benches per ISO/IEC 17025-accredited laboratories.
How is data security handled during Bluetooth transmission?
All Bluetooth communications use AES-128 encryption; pairing requires manual confirmation on both device and host, and no data is stored on the mobile device beyond the active session unless explicitly saved by the user.
