Overview
The KANOMAX Model 65Ser is a high-precision, multi-parameter thermal anemometer engineered for rigorous environmental and HVAC system validation in laboratories, cleanrooms, industrial ventilation audits, and indoor air quality (IAQ) assessments. Utilizing constant-temperature anemometry (CTA), the instrument maintains a stable temperature differential between the heated sensing element and ambient air, enabling highly responsive and linear velocity measurements across turbulent and laminar flow regimes. Unlike cup or vane anemometers, the 65Ser’s hot-wire/hot-film sensor technology delivers sub-second response times (<100 ms), minimal flow disturbance, and reliable low-velocity detection down to 0.05 m/s—critical for duct traverses, fume hood face velocity verification, and laminar airflow bench qualification per ISO 14644-3 and ASHRAE 110.
Key Features
- Simultaneous real-time measurement and display of air velocity, volumetric flow rate (CFM or CMS), dry-bulb temperature, relative humidity, and differential pressure—enabling comprehensive airflow characterization without external instruments.
- Eight mechanically and electrically compatible probe options—including straight, 90° bent, telescopic, low-velocity, and high-temperature variants—allow rapid adaptation to diverse duct geometries, confined spaces, and specialized applications such as ISO Class 5 cleanroom supply diffuser testing.
- Intuitive duct flow calculation engine accepts user-input dimensions for rectangular, circular, or oval cross-sections; automatically computes area and integrates velocity profiles using industry-standard traverse methods (e.g., log-linear or equal-area).
- Onboard statistical processing computes mean, minimum, maximum, and standard deviation over user-defined sampling intervals—essential for GLP-compliant reporting and HVAC commissioning documentation.
- Rugged aluminum housing with IP54-rated ingress protection ensures operational reliability in demanding field environments, while internal lithium-polymer battery supports >10 hours of continuous logging at 1 Hz sampling rate.
Sample Compatibility & Compliance
The 65Ser is validated for use with non-corrosive, non-condensing air streams within its specified environmental envelope (−20 to +70 °C, 2–98% RH). Probes are constructed from platinum-coated tungsten wire or thin-film ceramic substrates, certified to JIS B 7950 and compliant with ISO 7726 Annex B for thermal comfort instrumentation. The system supports traceable calibration via NIST-traceable reference standards, and all measurement data adhere to ISO/IEC 17025 requirements when used with documented procedures. For regulated environments, the device meets foundational criteria for HVAC performance verification under EU GMP Annex 1 (2022), USP , and FDA Guidance for Environmental Monitoring in Aseptic Processing Facilities.
Software & Data Management
Data export is supported via USB-C interface to KANOMAX’s proprietary PC software (Windows 10/11 compatible), which enables time-stamped CSV export, graphical trend analysis, duct traverse mapping, and customizable report generation (PDF/Excel). Audit trail functionality logs operator ID, timestamp, probe serial number, and calibration status for each measurement session—facilitating compliance with 21 CFR Part 11 where electronic records are retained. Firmware updates are delivered through signed binaries, ensuring integrity and version control across fleet deployments.
Applications
- HVAC system balancing and TAB (Testing, Adjusting, Balancing) per ASHRAE Guideline 1 and NEBB standards.
- Cleanroom classification and re-certification (ISO 14644-1/2), including supply air uniformity assessment and recovery time evaluation.
- Fume hood and biosafety cabinet face velocity surveys per ANSI/ASHRAE 110 and EN 14175.
- Industrial exhaust stack monitoring and local exhaust ventilation (LEV) system validation.
- Academic and industrial research requiring high-temporal-resolution airflow dynamics, such as boundary layer studies or thermal plume characterization.
FAQ
Does the Model 65Ser support automated duct traverse sequences?
Yes—the instrument allows pre-programmed point-by-point traverse grids for rectangular and circular ducts, with audible/visual prompts and auto-averaging per point.
Can measurement data be exported directly to Excel without proprietary software?
Raw logged data is stored in universal CSV format; no proprietary software is required for basic import and analysis.
Is the device suitable for outdoor wind speed measurement?
It is not designed for unshielded outdoor use due to sensitivity to rain, direct solar radiation, and particulate contamination—intended for indoor and semi-conditioned environments only.
What is the recalibration interval recommendation?
KANOMAX recommends annual recalibration against a certified reference anemometer or accredited lab, with interim verification using zero-flow and known-velocity check points.
Are probe calibration certificates included with each unit?
Each probe ships with a factory calibration certificate traceable to Japanese Industrial Standards (JIS), including uncertainty values and environmental conditions at time of calibration.
