Kanomax Model 6113 Intelligent Thermal Anemometer with Integrated Pressure & Temperature Measurement

Overview

The Kanomax Model 6113 is a portable, multifunctional thermal anemometer engineered for simultaneous, real-time measurement of air velocity, static pressure differential, and ambient temperature in HVAC commissioning, cleanroom validation, industrial ventilation assessment, and environmental monitoring applications. Its operational principle relies on constant-temperature anemometry (CTA), where a heated sensor element experiences convective cooling proportional to local airflow velocity—enabling stable, low-flow sensitivity down to 0.1 m/s without mechanical moving parts. Unlike cup or vane anemometers, the thermal sensing architecture provides rapid response time (<1 s), minimal flow disturbance, and immunity to directional misalignment errors. The integrated pressure transducer employs piezoresistive technology calibrated for bidirectional differential pressure across ducts, grilles, and filter banks, while the thermistor-based temperature sensor ensures traceable thermal readings compliant with ISO 7726 and ASHRAE Guideline 12. Designed for field-deployed metrology, the unit meets IEC 61000-4 electromagnetic compatibility standards and operates reliably across a broad thermal envelope (0–100 °C ambient).

Key Features

• Triple-parameter acquisition: Simultaneous logging of velocity, temperature, and differential pressure in a single instrument sweep
• High-resolution thermal velocity sensing: 0.1 m/s resolution with ±(3% rdg + 0.1) m/s accuracy validated per ISO 16814 Annex B
• Dual-range pressure module: ±5 kPa full-scale range with ±(3% rdg + 0.01 kPa) accuracy; suitable for filter integrity testing and duct static pressure profiling
• Onboard thermal printer: Immediate hardcopy output of measurement sessions—including timestamp, parameter values, and statistical summaries (max/min/avg)
• Internal data logger: Stores up to 100 complete test records with metadata (date/time, operator ID via manual entry, unit configuration)
• RS-232C serial interface: Enables direct communication with PC-based data acquisition software for batch export and compliance reporting
• Field-serviceable probe design: Interchangeable sensor heads support future calibration upgrades and application-specific configurations (e.g., extended-temperature probes)
• Battery-powered operation: Six AA cells provide ≥12 hours continuous use; low-battery indicator and auto-power-off prevent data loss

Sample Compatibility & Compliance

The Model 6113 is optimized for gaseous media under standard atmospheric conditions (dry air, 101.3 kPa). It is not rated for corrosive, explosive, or particulate-laden environments exceeding ISO 14644 Class 8 cleanliness. Calibration is traceable to JCSS (Japan Calibration Service System) standards through Kanomax’s A2LA-accredited calibration laboratory (Certificate No. 2090.01). The device complies with ISO 9001:2015 quality management requirements for manufacturing and supports GLP/GMP documentation workflows via exported CSV logs with audit-ready timestamps. While not intrinsically safe, it satisfies EN 61326-1 for electromagnetic immunity in industrial environments.

Software & Data Management

Data retrieval occurs via RS-232C using Kanomax’s proprietary Windows-compatible software (v3.2+), which parses raw serial streams into structured .csv files. Each record includes measurement epoch, parameter values, sensor status flags, and user-entered identifiers. The software supports statistical post-processing (standard deviation, trend charts), report generation in PDF format, and alignment with ASHRAE Standard 111 verification protocols. All stored data retains immutable timestamps and cannot be edited post-acquisition—supporting 21 CFR Part 11 electronic record integrity when used with password-protected operator accounts and system audit logs.

Applications

• HVAC system balancing and airflow verification per SMACNA and ASHRAE Handbook procedures
• Cleanroom air change rate calculation and ISO 14644-3 classification surveys
• Fume hood face velocity mapping and containment performance validation
• Filter bank pressure drop monitoring during routine maintenance
• Industrial exhaust stack characterization and dilution ventilation assessment
• Indoor air quality (IAQ) baseline studies requiring concurrent thermal and aerodynamic metrics

FAQ

Is the Model 6113 suitable for outdoor wind speed measurements?
No. Its thermal sensor is optimized for controlled indoor environments and lacks weatherproofing, solar radiation shielding, or gust-response compensation required for meteorological applications.
Can the built-in printer operate without a PC connection?
Yes. The thermal printer functions autonomously during measurement—no external host or driver installation is required.
Does the pressure measurement require zeroing before each use?
Yes. A manual zero function is provided to null ambient offset prior to differential pressure measurement, especially critical after transport or temperature shifts.
What is the recommended recalibration interval?
Kanomax recommends annual calibration against NIST-traceable references; more frequent verification is advised in high-use or critical compliance settings.
Are replacement probes available for high-temperature or high-humidity conditions?
Yes. Kanomax offers optional probe variants rated to 150 °C (Model 6114-HT) and condensation-resistant designs (Model 6115-DR), both mechanically and electrically compatible with the 6113 main unit.
