KANOMAX Model 6113 Hot-Wire Anemometer

Overview

The KANOMAX Model 6113 Hot-Wire Anemometer is a precision-engineered thermal anemometer designed for reliable, real-time measurement of air velocity in demanding environmental and industrial settings. Based on constant-temperature anemometry (CTA), the instrument maintains a heated platinum wire sensor at a fixed temperature above ambient; convective heat loss from the wire is directly correlated to local airflow velocity via calibrated thermal transfer relationships. This principle enables high-sensitivity detection across a broad dynamic range—from low-velocity laminar flows in cleanrooms and HVAC ducts to turbulent high-velocity airstreams in exhaust systems and wind tunnels. Unlike cup or vane anemometers, the hot-wire design offers minimal flow disturbance, sub-second response time (<100 ms), and directional insensitivity—making it especially suitable for spatially constrained or unsteady flow environments. The Model 6113 integrates a robust handheld unit with interchangeable probe assemblies, enabling rapid field maintenance without system recalibration.

Key Features

• Interchangeable probe architecture: Field-replaceable sensing probes maintain metrological traceability without requiring full-system recalibration—critical for continuous monitoring in regulated facilities.
• Simultaneous multi-parameter acquisition: Measures and logs air velocity, air temperature, and differential pressure (with optional pressure module) in synchronized time-stamped records.
• Large backlit LCD display: High-contrast 128 × 64 pixel screen supports clear visualization of real-time values, trend graphs, and unit configuration—even under low-light or high-glare conditions.
• Dual-output interface: Standard RS-232C port supports direct PC connection for data logging, remote control, and firmware updates; optional analog output (4–20 mA or 0–5 V) enables integration into SCADA or building management systems (BMS).
• Ruggedized enclosure: IP54-rated housing resists dust ingress and incidental water splashing—validated for operation inside ventilation ducts, fume hoods, and industrial enclosures.
• Thermal drift compensation: Embedded temperature and humidity sensors actively correct velocity readings for ambient thermal effects across the full 0–100 °C operating range.

Sample Compatibility & Compliance

The Model 6113 is compatible with standard KANOMAX hot-wire probes (e.g., 0300 series) and optional pitot-static or thermocouple-integrated variants. It meets IEC 61000-4 electromagnetic compatibility (EMC) requirements for industrial environments and conforms to JIS B 7554 (Japanese Industrial Standard for anemometers). While not intrinsically safe, its low-power circuitry (≤2 W) and non-sparking probe design permit use in non-hazardous classified areas per NEC Class I, Division 2 guidelines. Data integrity complies with GLP-aligned practices: timestamped records include operator ID fields, measurement mode flags, and sensor health diagnostics—supporting audit readiness in pharmaceutical HVAC validation (per ISO 14644-3) and laboratory environmental monitoring (per ISO/IEC 17025).

Software & Data Management

KANOMAX provides Windows-compatible data acquisition software (AnemoScope™ v3.x) supporting real-time graphing, statistical analysis (mean, min/max, standard deviation), and export to CSV, Excel, or PDF formats. All stored datasets include embedded metadata: probe serial number, calibration due date, ambient conditions, and user-defined test IDs. Audit trail functionality logs all configuration changes and data export events—meeting baseline requirements for FDA 21 CFR Part 11 compliance when deployed with electronic signature-enabled workflows. Firmware updates are delivered via signed binary packages with SHA-256 checksum verification.

Applications

• HVAC system commissioning and routine balancing per ASHRAE Guideline 12
• Cleanroom airflow uniformity mapping (ISO 14644-3 Class 5–8)
• Pharmaceutical facility environmental qualification (IQ/OQ/PQ protocols)
• Industrial exhaust stack velocity profiling for emissions reporting (EPA Method 2)
• Wind tunnel calibration and boundary layer characterization
• Academic aerodynamics research requiring high temporal resolution

FAQ

Is the Model 6113 suitable for outdoor use in rain or snow?

No—the unit is rated IP54 and intended for indoor or sheltered environments only. Prolonged exposure to precipitation may compromise sensor accuracy and electronics longevity.
Can the device be calibrated in-house using NIST-traceable standards?

Yes—KANOMAX supplies accredited calibration certificates and optional portable calibration kits (e.g., wind tunnel simulators with certified reference anemometers) for interval verification per ISO/IEC 17025 Clause 6.5.
Does the analog output support both 4–20 mA and 0–5 V simultaneously?

No—output type must be selected during configuration; switching requires reinitialization via RS-232C command sequence.
How frequently does the hot-wire sensor require cleaning or replacement?

Under typical indoor conditions, cleaning with isopropyl alcohol every 3–6 months suffices; probe replacement is recommended after 2 years of continuous operation or following exposure to oil mist, particulate-laden air, or condensation.
Is pressure measurement capability built-in or strictly optional?

Differential pressure measurement requires the separately ordered DP-6113 module; the base unit measures only velocity and temperature.
