KANOMAX 6500 Series Hot-Wire Anemometer System

Overview

The KANOMAX 6500 Series Hot-Wire Anemometer System is a precision-engineered environmental monitoring instrument designed for simultaneous, real-time measurement of air velocity, volumetric airflow, temperature, relative humidity, and differential pressure. Based on constant-temperature anemometry (CTA) principles, the system utilizes thermally sensitive platinum-wire probes whose resistance changes proportionally with convective heat loss—enabling highly responsive and repeatable velocity quantification across laminar and turbulent flow regimes. Unlike cup or vane anemometers, thermal anemometers offer superior low-velocity sensitivity (down to 0.01 m/s), minimal flow disturbance, and rapid response times (<100 ms), making them suitable for HVAC commissioning, cleanroom qualification, fume hood validation, and indoor air quality (IAQ) assessments per ISO 14644-3, ASHRAE Standard 110, and EN 13779.

Key Features

• Multi-parameter acquisition: Simultaneous display and logging of air velocity (m/s), calculated airflow (m³/h or CFM), ambient temperature (°C/°F), relative humidity (%RH), and differential pressure (Pa or inH₂O).
• Modular probe architecture: Supports eight standardized hot-wire probe models—including straight, bent, telescopic, and multi-point array variants—enabling application-specific configuration without recalibration.
• On-device volumetric flow computation: Users input duct geometry (rectangular, circular, or irregular cross-section) and dimensions; the system automatically computes total airflow using integrated velocity profiling algorithms.
• Statistical data processing: Real-time calculation of mean, maximum, minimum, and standard deviation across user-defined sampling intervals—critical for stability assessment during HVAC balancing or ISO Class verification.
• Robust environmental operation: Certified for continuous use across –20 to +70 °C and 2.0–98.0% RH, with IP54-rated housing ensuring dust and splash resistance during field deployment.
• Embedded memory and export capability: Stores up to 20,000 timestamped records internally; data export via USB interface supports CSV and Excel-compatible formats for traceable reporting.

Sample Compatibility & Compliance

The 6500 Series is compatible with KANOMAX-certified hot-wire probes calibrated per ISO/IEC 17025-accredited procedures at the manufacturer’s Yokohama facility. Probe interchangeability maintains traceability to NIST-traceable standards without requiring field recalibration. The system meets electromagnetic compatibility requirements per IEC 61326-1 (industrial environment) and safety compliance per IEC 61010-1. Its measurement methodology aligns with ASTM D5465 (Standard Test Method for Air Velocity Measurements Using Thermal Anemometers) and supports documentation workflows compliant with ISO/IEC 17025, FDA 21 CFR Part 11 (when paired with validated software), and GLP audit requirements.

Software & Data Management

KANOMAX provides optional PC-based software (KANOMAX DataViewer v4.x) supporting bidirectional communication, customizable report templates, and automated generation of calibration certificates. All stored measurements include embedded metadata: date/time stamp, probe ID, operator ID (user-configurable), and environmental conditions. Audit trail functionality logs parameter changes, data exports, and firmware updates—fulfilling ALCOA+ data integrity criteria. Raw data files are unencrypted and human-readable, enabling third-party integration with LIMS or building management systems (BMS).

Applications

• HVAC system commissioning and TAB (Testing, Adjusting, Balancing) per ASHRAE Guideline 1.
• Cleanroom airflow uniformity mapping and ISO 14644-3 classification testing.
• Fume hood face velocity validation and containment performance verification.
• Industrial ventilation system efficiency audits and OSHA-compliant exposure assessment.
• Research-grade boundary layer studies and wind tunnel calibration support.
• Indoor environmental quality (IEQ) monitoring in healthcare, pharmaceutical, and academic facilities.

FAQ

What probe types are supported by the 6500 Series?
The system accepts eight KANOMAX-certified hot-wire probes—models 6511 (straight), 6512 (90° bent), 6513 (telescopic), 6521 (dual-sensor), 6531 (3-point array), 6532 (5-point array), 6541 (high-temp), and 6551 (low-velocity). Each includes individual calibration certificate.
Does the instrument require annual recalibration?
Yes. KANOMAX recommends annual recalibration at an ISO/IEC 17025-accredited laboratory. Field zeroing is possible using the built-in purge function, but does not replace full calibration.
Can the device calculate airflow in non-rectangular ducts?
Yes. Users manually define irregular cross-sections by entering coordinate points or selecting from predefined shapes (trapezoidal, oval, annular); the system applies numerical integration to derive area-weighted average velocity.
Is the internal memory battery-backed?
Yes. Data retention is maintained for ≥72 hours after power loss, preventing record corruption during unexpected shutdowns.
What is the typical probe response time?
All hot-wire probes exhibit ≤100 ms (τ₉₀) response time under standard conditions (25 °C, 50% RH), verified per ASTM D5465 Annex A2.
