KANOMAX 65 Series Intelligent Thermal Anemometer

Overview

The KANOMAX 65 Series Intelligent Thermal Anemometer is a high-precision, multi-parameter environmental monitoring instrument engineered for rigorous field and laboratory applications in HVAC commissioning, cleanroom validation, industrial ventilation assessment, and indoor air quality (IAQ) studies. Utilizing constant-temperature anemometry (CTA) — a well-established thermal sensing principle — the device measures airflow velocity by detecting convective heat loss from a heated sensor element, enabling stable, low-drift response across its full 0.01–50.0 m/s range. Integrated with calibrated thermistor-based temperature and capacitive humidity sensors, plus a piezoresistive differential pressure transducer, the 65 Series delivers synchronized, time-stamped measurements of air velocity, temperature, relative humidity, and static/differential pressure. Its modular probe architecture supports eight standardized probe configurations — including vane, hot-wire, and pitot-static variants — allowing users to select optimal geometry and thermal response characteristics for ducts, grilles, laminar flow hoods, or open-space profiling.

Key Features

• Simultaneous real-time acquisition of air velocity, temperature, relative humidity, and pressure — all traceable to NIST-traceable calibration standards.
• Thermal anemometer core with dual accuracy specification: ±2% of reading or ±0.015 m/s (whichever is greater), validated per ISO 16813 and ASHRAE Guideline 12.
• Temperature measurement range −20 to +70 °C with ±0.5 °C accuracy; humidity range 2.0–98.0 %RH with tiered uncertainty (±2.0 %RH below 80 %RH; ±3.0 %RH above).
• Onboard statistical engine supporting live calculation of mean, maximum, minimum, and standard deviation — essential for ISO 14644-3 cleanroom airflow uniformity reporting.
• Internal memory capacity of 20,000 data points with timestamping, enabling unattended logging over extended periods without external hardware.
• USB interface compliant with USB 2.0 Full-Speed protocol; supports direct connection to Windows/Linux PCs for firmware updates and bulk data export in CSV format.
• 0–1 V analog output for integration into building management systems (BMS) or PLC-controlled environmental monitoring networks.
• Rugged handheld form factor (88 × 188 × 41 mm, 400 g) with IP54-rated enclosure, suitable for operation in non-hazardous industrial environments per IEC 60529.

Sample Compatibility & Compliance

The 65 Series accommodates a broad spectrum of sampling geometries through its eight mechanically and electrically compatible probe options — including flat-plate, spherical, and retractable probes — each individually calibrated and supplied with certificate of conformance. Probe interchangeability is achieved via a standardized 6-pin LEMO connector with automatic sensor identification, eliminating manual configuration errors. The instrument meets electromagnetic compatibility requirements per EN 61326-1:2013 (industrial environment) and safety standards per IEC 61010-1:2010 (CAT II 300 V). While not certified for intrinsic safety, its design aligns with general-purpose environmental monitoring practices under ISO/IEC 17025-accredited laboratories and supports audit readiness for FDA 21 CFR Part 11-compliant data handling when used with validated software workflows.

Software & Data Management

Data retrieval and post-processing are supported via KANOMAX’s proprietary PC application (Windows 10/11 compatible), which enables batch export, graphical trend analysis, and report generation conforming to ISO 14644-1 and ASHRAE Standard 111 templates. Raw data files include metadata headers specifying probe ID, calibration date, operator ID, and environmental conditions at time of capture. Audit trails are maintained for all configuration changes and data exports. For enterprise integration, the USB HID-class interface allows script-driven control using Python (pySerial) or LabVIEW, facilitating custom automation in GLP/GMP-regulated environments where procedural traceability is mandated.

Applications

• HVAC system balancing and TAB (Testing, Adjusting, and Balancing) per ANSI/ASHRAE Standard 111.
• Cleanroom airflow visualization and uniformity verification per ISO 14644-3 Annex B.
• Pharmaceutical facility environmental monitoring during qualification of air handling units (AHUs) and isolators.
• Occupational health assessments of local exhaust ventilation (LEV) performance per OSHA Technical Manual Section III: Chapter 5.
• Academic and industrial research involving convective heat transfer coefficient estimation and boundary layer characterization.
• Validation of fume hood face velocity and containment integrity per ANSI/AIHA Z9.5.

FAQ

Does the 65 Series support ISO/IEC 17025-compliant calibration documentation?
Yes — each unit ships with a factory calibration certificate referencing NIST-traceable standards; optional accredited calibration services are available through KANOMAX-authorized labs.
Can the instrument log data autonomously without a connected PC?
Yes — internal memory stores up to 20,000 timestamped records; logging intervals are programmable from 1 second to 24 hours.
Is probe auto-recognition mandatory for accurate measurement?
Yes — the LEMO interface transmits probe-specific calibration coefficients and physical parameters (e.g., effective area, thermal time constant) to ensure correct velocity computation.
What pressure reference does the ±5.00 kPa range correspond to?
The pressure sensor measures differential pressure relative to ambient atmospheric pressure; it is not intended for absolute pressure applications.
Are firmware updates backward-compatible with older probe models?
Firmware v3.2 and later maintain full compatibility with all eight legacy and current probe types; version history and release notes are published on KANOMAX’s global technical support portal.
