Overview
The KANOMAX KA26 Thermal Anemometer is an engineered solution for precise, real-time environmental validation in controlled environments—specifically designed for pharmaceutical cleanrooms (ISO 14644-1 Class 5–8), microelectronics fabrication facilities, aseptic processing suites, and HVAC commissioning in GMP-regulated settings. It operates on constant-temperature anemometry (CTA) principles: a heated thermistor sensor detects convective heat loss proportional to airflow velocity, enabling high-sensitivity measurement across low-to-moderate flow regimes typical of laminar flow hoods, supply diffusers, and return grilles. Unlike cup or vane anemometers, the KA26’s thermal sensing architecture eliminates mechanical inertia and directional bias—critical for capturing transient airflow patterns during smoke studies, filter integrity verification, and ISO 14644-3 airflow uniformity mapping. Its integrated temperature and differential pressure channels support simultaneous multi-parameter monitoring per ISO 14644-2 Annex B and EU GMP Annex 1 §4.34 requirements for environmental qualification.
Key Features
- Triple-parameter real-time acquisition: air velocity (0.00–50.0 m/s), temperature (−20.0–100.0 °C), and differential pressure (±5.00 kPa) measured concurrently with synchronized timestamps.
- 3.5-inch resistive touchscreen display with dual-view mode: numeric readout paired with dynamic analog bar graph—enabling rapid visual assessment of parameter stability and trend deviation during live testing.
- Configurable pass/fail threshold logic: users define upper/lower limits per parameter; system triggers audible alarm and color-coded screen alert upon violation—supporting documented compliance checks per FDA 21 CFR Part 11 Annex A (audit-ready event logging).
- Wireless probe-body communication via Bluetooth 5.0: eliminates cable constraints during duct traverse, ceiling-mounted diffuser evaluation, or ISO 14644-3 “as-built” airflow visualization—ensuring ergonomic access without signal degradation.
- Modular, bendable probe assembly: interchangeable sensor heads with telescoping extension rod (up to 1240 mm); no auxiliary fixtures required for hard-to-reach locations such as HEPA filter banks or interstitial ceiling plenums.
- On-device statistical processing: automatic calculation and display of min/max/mean values over user-defined sampling intervals—essential for ISO 14644-3 airflow uniformity reporting and EU GMP Annex 1 §4.37 averaging protocols.
Sample Compatibility & Compliance
The KA26 is validated for use in clean, non-corrosive, particle-free airstreams—consistent with ISO 21501-4 and IEST-RP-CC006.1 specifications for cleanroom instrumentation. It is not rated for explosive atmospheres (ATEX), high-humidity condensing conditions (>95% RH), or chemically aggressive gases. Its design supports adherence to multiple regulatory frameworks: data integrity features (timestamped records, user-accessible audit trail) align with FDA 21 CFR Part 11 and EU Annex 11 requirements; measurement uncertainty budgeting complies with ISO/IEC 17025:2017 Clause 7.6.1; and its calibration traceability path references NIST-traceable standards through KANOMAX Japan’s JCSS-accredited calibration lab. The instrument meets CE marking requirements under EMC Directive 2014/30/EU and RoHS 2011/65/EU.
Software & Data Management
Data export occurs via USB-C connection or Bluetooth pairing to KANOMAX’s proprietary PC software (KA26 Manager v3.x), which generates CSV- and PDF-formatted reports compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate). Each record includes operator ID, location tag, timestamp, environmental conditions, and status flags (e.g., “alarm triggered”, “probe disconnected”). The software supports automated report templating aligned with ISO 14644-3 test plans—including tabular summaries of point-by-point velocity deviations from target setpoints and graphical overlays for airflow vector analysis. All firmware updates are digitally signed and version-locked to prevent unauthorized modification—meeting GLP/GMP configuration management expectations.
Applications
- Pharmaceutical cleanroom qualification: ISO 14644-3 airflow velocity mapping at critical process zones (filling lines, isolators, RABS), including unidirectional airflow verification per EU GMP Annex 1 §4.33.
- Electronics manufacturing: laminar flow hood certification, clean bench performance validation, and semiconductor fab tool exhaust monitoring.
- HVAC system commissioning: duct static pressure balancing, terminal unit (VAV box) calibration, and total air volume verification using traverse methods per ASHRAE Guideline 12-2020.
- Indoor air quality (IAQ) surveys: ventilation rate estimation via tracer gas dilution correlation, occupancy-based airflow demand assessment, and thermal comfort parameter logging per ASHRAE Standard 55.
- Research & development: aerodynamic characterization of prototype enclosures, filtration efficiency testing, and thermal management validation in medical device packaging environments.
FAQ
Is the KA26 suitable for ISO 14644-3 Class 5 cleanroom airflow uniformity testing?
Yes—the instrument’s ±0.015 m/s base accuracy, sub-second response time, and 0.01 m/s resolution in low-flow ranges meet the metrological requirements for point measurements at 0.45 m/s ±20% targets.
Can measurement data be exported in a 21 CFR Part 11-compliant format?
Yes—when used with KA26 Manager software, all records include electronic signatures, immutable timestamps, and audit trails meeting Part 11 Subpart B requirements for closed systems.
What is the recommended calibration interval for GMP environments?
Per KANOMAX technical guidance and ISO/IEC 17025:2017, annual calibration is advised; however, risk-based assessment may justify shorter intervals (e.g., quarterly) for critical applications or after physical impact.
Does the probe require periodic cleaning or sensor replacement?
The platinum-coated thermistor sensor is sealed and requires only gentle isopropyl alcohol wipe-down between uses; no consumable replacement is specified within the 5-year design service life.
How does the KA26 handle temperature-induced drift during extended cleanroom monitoring?
Built-in temperature compensation algorithms dynamically correct velocity readings based on real-time ambient temperature input—validated across −20.0 to 100.0 °C per KANOMAX JIS C 1510-2015 test protocol.
