KANOMAX KA26/KA36 Portable Thermal Anemometer

Overview

The KANOMAX KA26/KA36 Portable Thermal Anemometer is a high-precision, multi-parameter environmental monitoring instrument engineered for field and laboratory applications requiring simultaneous measurement of air velocity, temperature, and differential pressure. Based on constant-temperature anemometry (CTA), the device employs a thermally sensitive platinum resistor sensor whose heat dissipation correlates directly with local airflow velocity—enabling stable, low-inertia response across a wide dynamic range (0.00–50.0 m/s). Unlike cup or vane anemometers, thermal sensing provides true vector-averaged velocity data in turbulent or low-velocity environments, making it suitable for HVAC commissioning, cleanroom airflow validation, industrial ventilation surveys, and indoor air quality (IAQ) assessments per ISO 16814, ASHRAE Standard 62.1, and EN 13779. The instrument’s compact, ergonomic architecture integrates all core electronics—including rechargeable lithium-ion power management, real-time signal conditioning, and dual-mode display processing—into a single handheld unit weighing only 600 g.

Key Features

• Simultaneous triple-parameter acquisition: air velocity, temperature (−20.0–100.0 °C), and differential pressure (±5.00 kPa) with independent calibration traceability.
• 3.5-inch resistive touch LCD supporting dual-view display—digital numeric readout paired with analog bar-graph visualization for intuitive trend interpretation and transient event capture.
• Bluetooth 5.0 wireless communication enables cable-free probe-to-body data transmission, eliminating mechanical constraints during duct traverse, ceiling diffuser testing, or remote exhaust sampling.
• Modular, interchangeable probe system with telescoping extension rod (adjustable from 260 mm to 1240 mm) and flexible articulation—no auxiliary fixtures required for hard-to-reach locations.
• Real-time statistical engine computes min/max/average values on-the-fly; data-hold function freezes instantaneous readings for documentation or verification under variable flow conditions.
• Configurable threshold-based alarm logic triggers visual highlight and audible alert when measured parameters exceed user-defined limits—supporting pass/fail workflows compliant with ISO 14644-3 and FDA guidance for environmental monitoring in GMP facilities.

Sample Compatibility & Compliance

The KA26/KA36 is validated for use with clean, dry air—consistent with standard operating conditions for HVAC system balancing, laminar flow hood certification, and pharmaceutical facility environmental qualification. Its thermal sensor design excludes particulate-laden or corrosive gas streams unless pre-filtered or conditioned per manufacturer guidelines. All measurement functions comply with fundamental metrological principles outlined in ISO/IEC 17025:2017 for calibration laboratories, and its documented accuracy specifications (e.g., wind speed: ±3% of reading or ±0.015 m/s, whichever is greater) meet the performance criteria referenced in ASTM D1078 (Standard Test Method for Air Velocity in Ventilation Ducts) and ISO 7726 (Ergonomics of the thermal environment – Instruments for measuring physical quantities). Device firmware supports audit-trail-enabled configuration logging, satisfying basic data integrity requirements under 21 CFR Part 11 for non-critical environmental monitoring applications.

Software & Data Management

Data transfer occurs via Bluetooth 5.0 or USB-C interface to Windows/macOS platforms using KANOMAX’s proprietary PC software (supplied). Raw measurements are stored internally in non-volatile memory—up to 5,000 timestamped records—with full metadata including date/time, sensor ID, and operational mode. Export formats include CSV and PDF report templates compatible with LIMS integration. The embedded real-time clock supports synchronized multi-instrument deployments, while configurable auto-power-off and low-battery warnings ensure uninterrupted field operation. Firmware updates are delivered via USB-C, maintaining backward compatibility with existing probe configurations and calibration certificates.

Applications

• HVAC system commissioning and TAB (Testing, Adjusting, Balancing) per SMACNA and NEBB standards.
• Cleanroom airflow uniformity mapping and ISO Class verification (ISO 14644-1/3).
• Industrial ventilation assessment for OSHA PEL compliance and local exhaust hood face velocity validation.
• Indoor air quality (IAQ) investigations including thermal comfort evaluation (PMV/PPD modeling inputs).
• Research-grade airflow profiling in wind tunnels, fume hoods, and environmental chambers.
• Energy audit support—quantifying fan efficiency, duct leakage, and system static pressure differentials.

FAQ

What distinguishes the KA26 from the KA36 model?
The KA36 includes an integrated pressure transducer and 1.5 m silicone pressure tubing kit; the KA26 measures only wind speed and temperature.
Is the instrument suitable for outdoor use in rain or high humidity?
The body is rated IP42 (drip-resistant); however, prolonged exposure to condensation or direct precipitation is not recommended—probe and body must remain within specified operating temperature and humidity ranges.
Can measurement data be exported to Excel or imported into building management systems (BMS)?
Yes—CSV export is supported; custom API integration requires third-party middleware due to proprietary Bluetooth packet structure.
Does the device support NIST-traceable calibration?
KANOMAX provides factory calibration certificates with uncertainty statements; users may arrange accredited third-party recalibration per ISO/IEC 17025 at certified labs.
How often should the thermal sensor be cleaned or recalibrated?
Visual inspection and gentle cleaning with isopropyl alcohol are recommended before each critical measurement session; annual recalibration is advised for GLP/GMP-regulated environments.
