KANOMAX 65Ser Hot-Wire Anemometer System

Overview

The KANOMAX 65Ser is a high-precision, multi-parameter hot-wire anemometer system engineered for laboratory-grade and field-deployable environmental airflow characterization. Based on constant-temperature anemometry (CTA), the instrument measures instantaneous air velocity by detecting convective heat loss from a fine platinum wire sensor maintained at a fixed temperature differential above ambient. This principle enables fast response times (<100 ms), low-velocity sensitivity, and high reproducibility across turbulent and laminar flow regimes. Unlike cup or vane anemometers, the 65Ser delivers true vector-averaged velocity measurements — critical for HVAC commissioning, cleanroom validation, fume hood performance testing, and indoor air quality (IAQ) assessments per ISO 14644, ASHRAE 110, and EN 13779 standards.

Key Features

• Simultaneous real-time measurement and display of air velocity (m/s), volumetric airflow (m³/h or CFM), static/differential pressure (kPa or inH₂O), ambient temperature (°C/°F), and relative humidity (%RH)
• Integrated duct airflow calculation engine: accepts user-input geometric parameters for rectangular, circular, or oval cross-sections — automatically computes total volumetric flow with traceable unit conversion
• Modular probe architecture supporting eight interchangeable hot-wire and thermistor-based probes — including retractable telescopic rods, flat-plate sensors, and high-temperature variants — all connected via a standardized locking interface with automatic probe recognition
• On-device statistical analysis: continuous calculation of minimum, maximum, and arithmetic mean values over user-defined time intervals; data-hold mode for stable reading capture during manual inspections
• Rugged industrial enclosure rated IP54 for dust and splash resistance; operating range extends from –20 °C to +70 °C with humidity tolerance up to 98.0% RH non-condensing
• Internal memory stores up to 20,000 timestamped measurement records (including date/time, all five parameters, and calculated airflow), exportable via USB to CSV-compatible formats for audit-ready reporting

Sample Compatibility & Compliance

The 65Ser accommodates diverse sampling configurations through its probe interchangeability system — enabling precise velocity profiling in ducts ≥50 mm diameter, grilles, diffusers, laminar flow hoods, and open-area ventilation studies. All probes comply with IEC 61000-4 electromagnetic immunity requirements and are calibrated traceably to JCSS (Japan Calibration Service System) reference standards. The system supports GLP-compliant workflows via configurable auto-log intervals, operator ID tagging (via optional PC software), and full audit trail generation. While not FDA 21 CFR Part 11 certified out-of-the-box, raw data files retain unalterable timestamps and parameter metadata — facilitating integration into validated QA/QC environments under ISO/IEC 17025 or GMP Annex 1 frameworks.

Software & Data Management

KANOMAX provides optional Windows-based configuration and data analysis software (65Ser Manager v3.x) that enables remote instrument setup, firmware updates, custom report templates, and batch export of stored datasets. The software supports automated calibration certificate generation, trend graphing with dual-Y axis overlays (e.g., velocity vs. temperature), and export to Excel, PDF, or XML formats compliant with internal lab information management systems (LIMS). All stored measurements include embedded probe serial numbers and calibration expiration dates — ensuring full metrological traceability throughout the data lifecycle.

Applications

• HVAC system balancing and TAB (Testing, Adjusting, Balancing) per ASHRAE Guideline 1 and SMACNA standards
• Cleanroom classification and recertification (ISO 14644-3) including uniformity mapping and airflow visualization support
• Fume hood face velocity verification and containment validation (ANSI/AIHA Z9.5)
• Industrial hygiene surveys for worker exposure assessment in ventilation-controlled workspaces
• Research applications requiring synchronized multi-parameter environmental logging (e.g., thermal comfort studies per ISO 7730)
• Educational use in mechanical engineering and environmental science laboratories for fluid dynamics pedagogy

FAQ

What probe types are compatible with the 65Ser system?

The 65Ser supports eight KANOMAX-certified probes — including models for low-velocity duct scanning (6505), high-temperature exhaust monitoring (6522), and compact surface airflow detection (6510). Each probe carries unique calibration coefficients stored in its EEPROM.
Does the 65Ser require annual recalibration?

Yes. KANOMAX recommends annual traceable recalibration against NIST-traceable standards to maintain ±2% accuracy compliance. Field verification using zero-air and certified flow benches is supported via built-in diagnostics.
Can the device calculate airflow in irregularly shaped ducts?

It supports only standard geometries: circular, rectangular, and oval cross-sections. For non-standard shapes, users must approximate using equivalent hydraulic diameter methods prior to input.
Is pressure measurement absolute or differential?

The integrated pressure sensor is configurable as either static pressure (relative to atmosphere) or differential pressure (across two ports), selectable via menu settings.
How is data integrity ensured during transfer from instrument to PC?

All exported CSV files contain MD5 checksums and embedded metadata (instrument ID, probe ID, calibration date, UTC timestamp), enabling cryptographic verification of data authenticity and completeness.
