Kanomax KA12 Multi-Channel Thermal Anemometer

Overview

The Kanomax KA12 Multi-Channel Thermal Anemometer is a precision-engineered environmental monitoring instrument designed for simultaneous, synchronized measurement of air velocity across up to four independent channels. Utilizing constant-temperature anemometry (CTA) principles, the system maintains thermal equilibrium between heated sensing elements and ambient airflow—enabling high-sensitivity detection of low-velocity laminar and turbulent flows. Unlike single-point instruments, the KA12 supports real-time comparative analysis across spatially distributed sampling points—critical for HVAC commissioning, cleanroom airflow mapping, duct traverse validation, and laboratory ventilation assessment. Its modular architecture centers on interchangeable probe compatibility, allowing users to select from ten standardized thermal anemometer probes—including omnidirectional, directional, ultra-low-flow, and high-temperature variants—each calibrated traceably to NIST-traceable standards.

Key Features

• Four-channel synchronous acquisition with independent zero and span adjustment per channel
• Modular probe interface supporting 10 Kanomax-certified thermal anemometer probes (e.g., 6501, 6511, 6521 series), all featuring plug-and-play recognition and auto-scaling
• High-resolution digital readout: 0.01 m/s resolution across full dynamic range
• RS-232C serial interface compliant with EIA/TIA-232-F specifications for direct PC connection and remote command control (SCPI-compatible protocol)
• Dual-mode analog output: user-selectable 0–5 V DC or 4–20 mA current loop, configurable per channel for integration with building management systems (BMS) or PLCs
• Rugged aluminum enclosure (IP20-rated) with front-panel LED indicators for channel status, communication activity, and power integrity
• Embedded real-time clock for timestamped data logging; internal memory stores up to 16,000 records (expandable via external USB storage)

Sample Compatibility & Compliance

The KA12 is compatible with Kanomax’s full suite of ISO 14644-3–aligned airflow probes, enabling compliance with cleanroom qualification protocols (e.g., ISO 14644-1, EU GMP Annex 1). Probe selection determines operational envelope: standard probes operate within 0–30 m/s at 0–60 °C and 0–100% RH; high-temp variants extend to 150 °C. The instrument meets IEC 61000-4 electromagnetic immunity requirements and carries CE marking under the EU EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. Data integrity conforms to ALCOA+ principles when used with validated software—supporting audit trails, electronic signatures, and 21 CFR Part 11–compliant configurations upon system-level validation.

Software & Data Management

Kanomax provides the KA12 Control & Analysis Suite (v3.2+), a Windows-based application supporting real-time multi-channel visualization, statistical reporting (mean, min/max, standard deviation, turbulence intensity), and export to CSV, Excel, or PDF. The software implements automated calibration verification workflows, drift compensation algorithms, and probe-specific correction factor tables. Raw data files include embedded metadata (probe ID, calibration date, operator ID, timestamp, environmental conditions). For regulated environments, optional IQ/OQ documentation packages and CSV-to-LIMS interface modules are available—facilitating integration into GLP/GMP quality systems requiring full data lifecycle traceability.

Applications

• HVAC system balancing and TAB (Testing, Adjusting, Balancing) per ASHRAE Guideline 111
• Cleanroom airflow uniformity and velocity profile mapping in pharmaceutical manufacturing suites
• Validation of laminar flow hoods, biosafety cabinets, and isolators per ISO 14644-3 Annex B
• Industrial ventilation surveys for occupational health compliance (OSHA 1910.94, ACGIH TLVs)
• Research-grade boundary layer studies in wind tunnels and environmental chambers
• Continuous monitoring of exhaust stack velocities with analog output integration into SCADA platforms

FAQ

How many probes can be connected simultaneously?
Up to four probes may be connected and measured concurrently—one per channel—with full independent configuration.
Is probe calibration traceable to national standards?
Yes—each probe ships with a certificate of calibration traceable to JCSS (Japan Calibration Service System), equivalent to ISO/IEC 17025 accreditation.
Can the KA12 log data without a PC connection?
Yes—the internal memory buffers time-stamped measurements autonomously; USB flash drive export is supported for offline transfer.
Does the analog output support HART protocol?
No—the 4–20 mA output is passive and non-smart; HART functionality requires external signal conditioners.
What is the maximum cable length between probe and main unit?
Standard shielded cables support up to 30 m; extended-length options (up to 100 m) are available with low-noise twisted-pair cabling and signal amplification.
