Kanomax Model 6113 Intelligent Thermal Anemometer

Overview

The Kanomax Model 6113 Intelligent Thermal Anemometer is a portable, multi-parameter environmental measurement instrument engineered for precision airflow characterization in HVAC commissioning, cleanroom validation, industrial ventilation assessment, and laboratory airflow studies. Based on constant-temperature anemometry (CTA), the device employs a heated platinum wire sensor whose thermal dissipation correlates directly with local air velocity—enabling stable, low-inertia response across turbulent and laminar flow regimes. Unlike cup or vane anemometers, the thermal principle provides true vector-averaged velocity readings at near-zero start-up thresholds (0.1 m/s), making it suitable for low-velocity applications such as duct leakage testing, fume hood face velocity verification, and laminar flow bench monitoring. Its integrated tri-sensor architecture simultaneously acquires wind speed, ambient temperature, and differential pressure—critical for calculating volumetric flow rates (e.g., CFM or m³/h) without external instrumentation.

Key Features

• Triple-sensor concurrent measurement: Air velocity (0.1–50.0 m/s), temperature (0–100 °C), and differential pressure (–5 to +5 kPa) captured in a single acquisition cycle.
• High-resolution thermal probe with 0.1 m/s velocity resolution and traceable calibration per ISO/IEC 17025-accredited procedures.
• Built-in thermal printer enabling real-time hardcopy output of measurement records—including timestamps, statistical summaries (max/min/average), and operator annotations—supporting GLP-compliant field documentation.
• Onboard data storage for up to 100 test sets with automatic metadata tagging (date, time, sensor ID, units); data export via RS-232C serial interface to PC-based analysis software or LIMS platforms.
• Modular probe design ensures interchangeability with other Kanomax thermal probes (e.g., 6114, 6115), allowing adaptation to specialized geometries (ducts, grilles, nozzles) without recalibration.
• Robust mechanical architecture: IP54-rated enclosure, 1.0 kg mass optimized for handheld stability during extended surveys; powered by six standard AA alkaline cells with >12 hours of continuous operation under typical duty cycles.

Sample Compatibility & Compliance

The Model 6113 is validated for use in non-corrosive, non-explosive gaseous environments within specified operating limits (5–80 %RH, 0–100 °C). It complies with IEC 61000-4 electromagnetic immunity standards and meets CE marking requirements for portable measuring instruments. While not intrinsically safe, its battery-powered design eliminates grounding risks in sensitive electrical environments. For regulatory workflows, the device supports audit-ready data integrity: printed reports include unique session IDs, measurement uncertainty statements (per stated accuracy specifications), and operator-defined test identifiers—facilitating alignment with ISO 14644-3 (cleanroom testing), ASHRAE 111 (airflow measurement procedures), and FDA 21 CFR Part 11–aligned documentation practices when paired with validated software.

Software & Data Management

Raw data from the Model 6113 is transmitted via RS-232C using ASCII protocol, enabling integration with custom scripts (Python, LabVIEW) or Kanomax’s legacy PC utility for CSV export and trend visualization. The analog 0–1 V output allows direct connection to PLCs or data loggers for continuous process monitoring. All stored datasets retain full parameter context (velocity + temp + pressure + timestamp), permitting post-hoc calculation of volumetric flow (Q = A × v × K_T × K_P) where cross-sectional area (A) is entered manually or imported from facility BIM models. No cloud dependency or proprietary firmware updates are required—the instrument operates autonomously with deterministic response timing.

Applications

• HVAC system balancing and TAB (Testing, Adjusting, Balancing) per NEBB and AABC protocols.
• Cleanroom ISO Class verification: supply/exhaust grille velocity mapping, unidirectional airflow uniformity checks.
• Fume hood and biosafety cabinet certification (ANSI/ASHRAE 110, EN 14175).
• Industrial exhaust stack profiling and duct traverse measurements (ASTM D5482, ISO 10780).
• Research-grade boundary layer studies requiring high temporal resolution (up to 1 Hz sampling rate).
• Environmental chamber airflow uniformity validation in pharmaceutical stability testing suites.

FAQ

Does the Model 6113 require annual recalibration?
Yes—Kanomax recommends traceable recalibration every 12 months or after 200 hours of cumulative operation, per ISO/IEC 17025 guidelines. Calibration certificates include uncertainty budgets for all three measured parameters.
Can the built-in printer operate without a PC connection?
Yes—the thermal printer functions entirely offline; data is printed immediately after each measurement or batch, with no driver or host software required.
Is the pressure sensor suitable for static pressure measurement in ducts?
It is designed for differential pressure only (e.g., across filters or orifices); static pressure measurement requires a separate reference port configuration not supported by the standard probe assembly.
What is the maximum allowable particulate concentration for reliable thermal sensor operation?
Operation is rated for ambient dust concentrations ≤1 mg/m³; higher levels necessitate optional stainless-steel probe shrouds and more frequent sensor cleaning per Kanomax Maintenance Bulletin KB-6113-04.
Are firmware updates available for the Model 6113?
No—this is a fixed-function embedded instrument; functionality is defined at manufacture and does not support field-upgradable firmware.
