KANOMAX 6715 Air Flow Hood

Overview

The KANOMAX 6715 Air Flow Hood is a precision-engineered, multi-parameter environmental measurement instrument designed for quantitative assessment of volumetric air flow in HVAC ducts, diffusers, grilles, and terminal devices. It operates on the principle of integrated velocity-area measurement using an internal array of calibrated sensors—primarily a pitot-static tube and/or a multi-point velocity matrix—combined with real-time differential pressure and thermohygrometric compensation. The unit simultaneously captures air flow rate (m³/h), face velocity (m/s), static differential pressure (Pa), ambient temperature (°C), and relative humidity (%RH) within a single measurement cycle. Its robust mechanical architecture, including a rotatable 3.5-inch color LCD display and built-in backpressure compensation algorithm, ensures stable and repeatable readings even under variable system resistance conditions. Designed and manufactured in Japan to stringent JIS and ISO 9001 quality standards, the 6715 meets international requirements for commissioning, balancing, and routine performance verification of ventilation systems in laboratories, cleanrooms, hospitals, and commercial buildings.

Key Features

• Simultaneous five-parameter measurement: air flow, velocity, differential pressure, temperature, and humidity
• Wide dynamic range: 40–4300 m³/h with resolution of 1 m³/h and accuracy of ±3% of reading ±10 m³/h
• Rotatable ±30° 3.5-inch color LCD display for ergonomic viewing in confined or overhead installations
• Integrated backpressure compensation to correct for flow resistance induced by the hood itself
• Bluetooth-enabled wireless data transmission to iOS/Android mobile devices via proprietary Kanomax Smart App
• Large onboard memory capacity: 8,000 measurement records with timestamp, location tagging, and operator ID support
• Comprehensive connectivity: USB interface for PC data export, RS-232 port for optional thermal printer integration
• Modular hood design with standardized 610 × 610 mm base and 10+ interchangeable sizes for diverse duct geometries
• Dual power options: 4 × AA alkaline batteries (9 h typical runtime) or external DC 5 V adapter

Sample Compatibility & Compliance

The KANOMAX 6715 is compatible with standard HVAC terminal devices including supply/return diffusers, VAV boxes, fan coil units, and laminar flow hoods. Its modular hood configurations accommodate rectangular, square, and elongated openings from 305 × 500 mm up to 1400 × 800 mm. The instrument complies with key industry-relevant standards including ASHRAE Guideline 12–2020 (for infection control), ISO 14644-3 (cleanroom testing), and EN 12599 (HVAC system commissioning). While not certified for intrinsic safety in hazardous locations, it is rated for use in non-explosive indoor environments per IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use). Its measurement traceability aligns with NIST-traceable calibration protocols when serviced by authorized KANOMAX calibration centers.

Software & Data Management

The KANOMAX 6715 supports two-tiered data handling: local storage and cloud-ready export. Onboard firmware enables timestamped logging, data review, selective deletion, battery status monitoring, and real-time clock synchronization. PC-based Kanomax Data Manager software (Windows-compatible) provides post-processing functions including flow profile visualization, statistical analysis (mean, min/max, standard deviation), report generation (PDF/CSV), and audit trail export. The mobile Smart App extends functionality with remote configuration, live sensor readouts, geotagging, photo annotation, and automatic synchronization to secure cloud storage—supporting GLP-compliant workflows where electronic records must meet FDA 21 CFR Part 11 requirements for signature, retention, and integrity.

Applications

• HVAC system commissioning and TAB (Testing, Adjusting, Balancing) in commercial and institutional buildings
• Cleanroom airflow validation per ISO 14644-3 and EU GMP Annex 1
• Infection control assessments in healthcare facilities (e.g., isolation rooms, operating theatres)
• Lab ventilation safety audits including fume hood face velocity verification
• Energy efficiency evaluations and retrocommissioning studies
• Regulatory compliance reporting for LEED, BREEAM, or local building codes
• Preventive maintenance of air handling units and terminal devices

FAQ

Is the KANOMAX 6715 still in production?
No—the 6715 has been officially discontinued and superseded by the KANOMAX 6720, which features an upgraded 4.3-inch touchscreen, extended battery life (~14 h), enhanced differential pressure accuracy (±0.25% ±1 Pa), and expanded mobile app functionality.
Can the 6715 be calibrated to meet ISO/IEC 17025 requirements?
Yes—when serviced by an ISO/IEC 17025-accredited calibration laboratory using NIST-traceable reference standards, full calibration certificates with uncertainty budgets are available upon request.
Does the device support automated report generation for regulatory submissions?
Yes—PC software generates customizable PDF reports compliant with ASHRAE, ISO, and national HVAC commissioning standards; electronic signatures and audit logs are supported via third-party document management systems.
What is the maximum allowable duct velocity for accurate measurement?
For optimal accuracy, inlet face velocity should remain within 0.15–15 m/s (matrix mode) or 0.15–40 m/s (pitot mode); velocities exceeding 40 m/s may compromise sensor linearity and require field verification.
Are replacement hoods and accessories still available?
Yes—KANOMAX continues to supply all standard and optional hood sizes, extendable poles, thermal printers, AC adapters, and sensor modules through authorized global distributors and service centers.
