Kanomax Model 65 Ser Intelligent Thermal Anemometer

Overview

The Kanomax Model 65 Ser Intelligent Thermal Anemometer is a precision-engineered, multi-parameter environmental measurement instrument designed for laboratory, industrial hygiene, HVAC commissioning, and cleanroom validation applications. Based on constant-temperature anemometry (CTA), it employs a thermally sensitive probe element whose heat dissipation correlates directly with local air velocity—enabling high-fidelity, real-time measurement across a wide dynamic range (0.01–50.0 m/s). Unlike conventional thermal anemometers limited to ambient temperature operation, the Model 65 Ser extends its functional envelope to −20 °C, making it uniquely suitable for cold-storage facilities, refrigerated transport validation, and low-temperature process monitoring. Its integrated sensor suite simultaneously captures air velocity, temperature, relative humidity, and differential pressure—providing synchronized, time-stamped environmental profiles essential for ISO 14644-3 airborne particle testing, ASHRAE 110 fume hood certification, and ISO 17025-compliant calibration workflows.

Key Features

• Multi-sensor fusion architecture: Simultaneous acquisition of air velocity, temperature (−20 to +70 °C), relative humidity (2.0–98.0 %RH), and differential pressure (±5.00 kPa) in a single handheld unit.
• Extended low-temperature capability: Validated operation down to −20 °C—enabling reliable measurements in cold-chain logistics, pharmaceutical cold rooms, and cryogenic pre-conditioning environments.
• High-resolution data logging: Internal memory stores up to 20,000 timestamped records with user-defined sampling intervals; supports USB mass storage mode for direct file transfer without proprietary drivers.
• Probe interchangeability: Compatible with eight dedicated Kanomax thermal probes (e.g., KA-23, KA-33, 6113-series), enabling rapid adaptation to ducts, laminar flow hoods, and confined spaces via standardized connector interface.
• On-device computation: Real-time statistical functions including min/max/average calculation, data hold, and automatic wind volume derivation upon input of duct cross-sectional geometry (rectangular, circular, or custom polygonal).
• Calibration traceability support: Built-in calibration reminder function aligned with ISO/IEC 17025 internal audit requirements; certificate of conformity includes NIST-traceable reference points for velocity, temperature, and humidity.

Sample Compatibility & Compliance

The Model 65 Ser is engineered for non-intrusive, in-situ environmental assessment across diverse physical media—including ambient indoor air, conditioned supply streams, exhaust ducts, and low-velocity laminar flows. Its thermal probe design minimizes flow disturbance and eliminates moving parts, ensuring long-term stability in dusty or humid installations. The instrument complies with IEC 61000-4 electromagnetic immunity standards and meets CE marking requirements for portable measuring instruments. For regulated environments, its data integrity features—including sequential record numbering, UTC timestamping, and CSV export format—support adherence to FDA 21 CFR Part 11 principles when used in conjunction with validated software workflows. It is routinely deployed in GLP-compliant HVAC performance qualification per ISO 14644-1 and USP environmental monitoring protocols.

Software & Data Management

Kanomax provides Windows-compatible configuration and analysis software (v3.2+), distributed as a signed installer with SHA-256 hash verification. The application enables remote instrument control via USB virtual COM port, real-time graphing of all four parameters, and batch export to industry-standard CSV files with UTF-8 encoding and Excel-compatible headers. Audit trail functionality logs all configuration changes, firmware updates, and data export events—including operator ID, timestamp, and action type—to support ISO 9001 documentation requirements. Raw datasets retain native resolution (0.01 m/s, 0.1 °C, 0.1 %RH) without interpolation or rounding, preserving metrological integrity for post-acquisition uncertainty analysis per GUM (JCGM 100:2008).

Applications

• HVAC system balancing and airflow verification in hospitals, laboratories, and pharmaceutical manufacturing suites.
• Cleanroom classification (ISO 14644-1 Class 5–8) via uniformity mapping of face velocity at HEPA filter banks.
• Fume hood face velocity surveys per ANSI/AIHA Z9.5 and EN 14175-3 standards.
• Refrigerated warehouse temperature/airflow correlation studies for cold chain validation.
• Occupational hygiene assessments of local exhaust ventilation (LEV) capture velocity per OSHA Technical Manual Section III: Chapter 4.
• Research-grade boundary layer characterization in aerodynamic test chambers and wind tunnel inlet conditioning zones.

FAQ

Does the Model 65 Ser require annual recalibration?
Yes—Kanomax recommends recalibration every 12 months or after 200 hours of field use, whichever occurs first, to maintain stated accuracy specifications. Calibration certificates include uncertainty budgets per ISO/IEC 17025 Annex A.
Can the device measure volumetric flow rate directly?
It calculates volumetric flow (m³/h or CFM) in real time when users input duct geometry (width, height, or diameter); no external computation is required.
Is the USB interface compatible with modern Windows OS versions?
Yes—the device operates in USB Mass Storage Class (MSC) mode, requiring no additional drivers on Windows 10/11, macOS 12+, or Linux kernel 5.4+.
What is the battery life under continuous logging mode?
With alkaline AA cells, typical runtime is 18–22 hours at 1-second sampling interval; lithium AA batteries extend this to >40 hours.
Are probe calibration certificates provided with each unit?
Each probe is supplied with a factory calibration report referencing NIST-traceable standards; full system calibration reports are available upon request at time of purchase.
