Kanomax Model 6113 Hot-Wire Anemometer

Overview

The Kanomax Model 6113 is a portable, multi-parameter thermal anemometer engineered for precision air velocity, temperature, and differential pressure measurement in HVAC commissioning, cleanroom validation, industrial ventilation assessment, and indoor air quality (IAQ) studies. Based on constant-temperature hot-wire anemometry, the instrument employs a fine platinum-coated thermistor probe that responds rapidly to convective heat loss proportional to airflow velocity. This principle enables stable, low-inertia measurements across turbulent and laminar flow regimes — critical for duct traverse surveys, fume hood face velocity verification, and ISO 14644-3 compliant airflow uniformity testing. Unlike cup or vane anemometers, the 6113 delivers true vector-averaged velocity readings at low flow rates (down to 0.1 m/s), making it suitable for low-velocity applications such as laminar flow hoods, biological safety cabinets, and underfloor air distribution systems.

Key Features

• Simultaneous real-time measurement of air velocity (0.1–50.0 m/s), ambient temperature (0–100 °C), and differential pressure (−5 to +5 kPa)
• Integrated thermal printer for on-site documentation — eliminates transcription errors and supports audit-ready field reporting
• Interchangeable probe design compatible with Kanomax’s family of hot-wire and thermocouple probes (e.g., 6114, 6115), enabling application-specific configuration without instrument replacement
• Onboard data logging for up to 100 test records, each storing timestamped velocity, temperature, and pressure values with statistical post-processing (min, max, mean, standard deviation)
• RS-232C serial interface for direct connection to PCs or data acquisition systems; supports ASCII protocol for integration into custom LabVIEW or Python-based QA workflows
• 0–1 V analog output for continuous monitoring via PLCs or building management systems (BMS)
• Robust ergonomic housing (210 × 120 × 133 mm, 1.0 kg) with battery-powered operation (6 × AA) for extended field use without AC dependency

Sample Compatibility & Compliance

The Model 6113 is validated for use in non-corrosive, non-explosive, particle-free airstreams typical of commercial HVAC ducts, laboratory exhaust systems, and clean manufacturing environments. Its operating temperature range (0–100 °C) and humidity tolerance (5–80 %RH) meet ANSI/ASHRAE Standard 111 requirements for field instrumentation accuracy under variable environmental conditions. While not intrinsically safe, the unit complies with IEC 61010-1:2010 for electrical safety in measurement equipment. For regulated pharmaceutical or medical device facilities, the device supports GLP-compliant data handling when paired with traceable calibration certificates (NIST-traceable calibration available upon request). It does not meet FDA 21 CFR Part 11 requirements natively but provides audit-ready printed outputs and timestamped digital logs suitable for manual review and signature in GMP-aligned documentation practices.

Software & Data Management

No proprietary software is bundled; however, the RS-232C interface allows seamless integration with third-party platforms including Excel-based macros, MATLAB scripts, or enterprise QA databases using standard terminal emulation (e.g., Tera Term, PuTTY). Each logged record includes date/time stamp, measurement mode identifier, and raw sensor outputs — facilitating traceability per ISO/IEC 17025 clause 7.7. The built-in statistics engine computes arithmetic mean, peak excursion (max/min), and sample count automatically — reducing post-test calculation burden during HVAC balancing reports or ISO 16813-compliant IAQ audits. Calibration history and user-defined test IDs can be appended manually to printed reports for full procedural transparency.

Applications

• HVAC system commissioning and TAB (Testing, Adjusting, Balancing) per ASHRAE Guideline 1
• Cleanroom airflow visualization and uniformity mapping (ISO 14644-3 Annex B)
• Fume hood and biosafety cabinet face velocity verification (ANSI/ASHRAE 110, NSF/ANSI 49)
• Industrial exhaust stack velocity profiling and volumetric flow estimation
• Thermal comfort assessment per ISO 7730 and ASHRAE Standard 55
• Validation of underfloor air distribution (UFAD) and displacement ventilation systems
• Educational aerodynamics labs requiring multi-sensor correlation of velocity, thermal, and static pressure fields

FAQ

Does the Model 6113 support automatic zeroing or auto-calibration?
No. The instrument requires manual zeroing before each measurement session using the dedicated “Zero” function. Full calibration must be performed annually or after physical impact, using NIST-traceable reference standards.
Can the internal memory be expanded beyond 100 records?
No. Memory capacity is fixed at 100 entries. Data must be offloaded via RS-232C or printed before overwriting occurs.
Is the thermal printer replaceable or serviceable in the field?
The integrated thermal print head is not user-replaceable. Replacement requires factory service; spare thermal paper rolls (Kanomax P/N 6113-PAPER) are field-installable.
What probe types are compatible with the Model 6113?
It accepts Kanomax hot-wire probes 6113-P, 6114-P, and 6115-P — differing in stem length, tip geometry, and temperature rating — all sharing the same connector interface and firmware recognition protocol.
Does the unit comply with EU CE marking requirements?
Yes. The Model 6113 carries CE marking per EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU, verified by third-party notified body testing.
