Kanomax 6113 Digital Thermal Anemometer

Overview

The Kanomax 6113 Digital Thermal Anemometer is a portable, multi-parameter environmental monitoring instrument engineered for precision airflow characterization in HVAC commissioning, cleanroom validation, industrial ventilation assessment, and laboratory airflow studies. Utilizing constant-temperature anemometry (CTA) — a robust thermal sensing principle where a heated sensor element maintains a fixed temperature differential relative to ambient air — the device delivers stable, low-inertia velocity measurements across a wide dynamic range. Unlike cup or vane anemometers, the thermal probe responds rapidly to transient flow changes and operates effectively at near-zero velocities (down to 0.1 m/s), making it suitable for laminar flow profiling, duct traverse surveys, and localized air curtain verification. Integrated temperature and differential pressure sensors enable simultaneous three-parameter acquisition, supporting comprehensive air system diagnostics without requiring multiple instruments.

Key Features

• Simultaneous real-time measurement of air velocity (0.1–50.0 m/s), temperature (0–100 °C), and differential pressure (–5 to +5 kPa)
• Thermal velocity sensor with 0.1 m/s resolution and traceable accuracy of ±(3% of reading + 0.1) m/s per ISO 16814:2014 and ASTM D1076-20 guidelines for thermal anemometer performance
• Built-in thermal printer enabling on-site hardcopy output of measurement records — ideal for audit-ready field documentation and GLP-compliant reporting
• Onboard data storage for up to 100 complete test sets, each including timestamped velocity, temperature, and pressure values
• Real-time statistical processing: automatic calculation and display of maximum, minimum, and arithmetic mean values during continuous sampling
• RS-232C serial interface for bidirectional communication with PCs or data loggers; supports ASCII protocol for integration into custom QA/QC software environments
• 0–1 V analog output for connection to PLCs, SCADA systems, or third-party recording devices
• Ergonomic handheld design (210 × 120 × 133 mm; 1.0 kg) powered by six standard AA batteries, enabling >15 hours of continuous operation under typical usage conditions

Sample Compatibility & Compliance

The Kanomax 6113 is designed for use with standard Kanomax thermal probes (including optional high-temperature and low-velocity variants), ensuring interchangeability across the 6113/6114/6115 series platform. It complies with electromagnetic compatibility requirements per IEC 61326-1:2020 for laboratory and industrial environments. While not certified for intrinsic safety, its non-sparking construction and battery-powered operation permit deployment in non-hazardous classified areas per NEC Class I, Division 2. The instrument supports traceable calibration via NIST-traceable reference standards and is routinely employed in facilities adhering to ISO 14644-3 (cleanroom testing), ASHRAE 111 (air system testing), and EU GMP Annex 1 (HVAC qualification). Measurement uncertainty budgets align with ISO/IEC 17025:2017 requirements when operated within specified environmental limits (5–80 °C ambient, ≤80 %RH).

Software & Data Management

Raw data export is supported via RS-232C using simple ASCII framing (CR/LF terminated lines), allowing seamless ingestion into Excel, MATLAB, LabVIEW, or LIMS platforms. No proprietary software installation is required. Each stored record includes date/time stamp, measurement mode identifier, and full parameter set. The built-in statistics engine operates independently of external software, providing immediate feedback during manual traverse protocols. For regulated environments, users may configure the device to generate printed reports with operator ID, location tag, and test sequence number — satisfying basic FDA 21 CFR Part 11 documentation expectations when combined with procedural controls (e.g., controlled logbooks and review signatures).

Applications

• HVAC duct velocity profiling and volumetric flow rate estimation (when combined with cross-sectional area input)
• Cleanroom unidirectional airflow uniformity mapping per ISO 14644-3 Annex B
• Fume hood face velocity verification and alarm threshold validation
• Filter leakage scanning support (as part of upstream/downstream comparative testing)
• Industrial drying oven and kiln airflow uniformity audits
• Exhaust stack screening and local exhaust ventilation (LEV) system balancing
• Academic aerodynamics labs for boundary layer and wake characterization at low-to-moderate Reynolds numbers

FAQ

Does the Kanomax 6113 require annual recalibration?
Yes — for metrological integrity and compliance with ISO/IEC 17025 or internal QA policies, annual recalibration against a NIST-traceable wind tunnel or calibrated reference anemometer is recommended.
Can the built-in printer operate without a PC connection?
Yes — the thermal printer functions autonomously; pressing the PRINT button outputs the current screen or last stored dataset directly.
Is the pressure measurement capability suitable for filter differential pressure monitoring?
Yes — the ±5 kPa range and 0.01 kPa base accuracy make it appropriate for HEPA/ULPA filter delta-P trending, though long-term drift compensation should be applied per manufacturer’s maintenance schedule.
What probe types are compatible with the 6113 unit?
All Kanomax thermal probes designated for the 6000-series platform, including the standard KANOMAX 6101 (general purpose), 6102 (high-temp), and 6103 (low-velocity) models.
Does the device support data logging at user-defined intervals?
No — the 6113 does not feature timed interval logging; data capture is manual or triggered via HOLD/STORE keypress. For automated time-series logging, consider the Kanomax 6501 or 6700 series with SD card expansion.
