Overview
The KANOMAX KA12+ Four-Channel Thermal Anemometer System is a precision-engineered environmental monitoring platform designed for simultaneous, synchronized measurement of air velocity across up to four independent sampling points. Utilizing constant-temperature anemometry (CTA) principles, the system maintains thermal equilibrium between heated sensing elements and ambient airflow—enabling high-fidelity detection of low-velocity laminar and turbulent flow regimes. Unlike single-point instruments, the KA12+ architecture supports real-time comparative analysis across spatially distributed locations—critical for HVAC commissioning, cleanroom validation, ventilation duct profiling, and laboratory airflow mapping. Its modular probe interface accommodates ten interchangeable thermal anemometer probes—including omnidirectional, directional, and miniature variants—each calibrated per ISO 16812 and traceable to JIS Z 8901 standards. The system operates within a certified environmental envelope (0–60 °C, 0–100% RH), ensuring metrological stability under demanding field conditions.
Key Features
- Four-channel synchronous acquisition with independent zero-offset and gain calibration per channel
- Modular probe compatibility: Supports 10 standardized KANOMAX thermal probes (e.g., 6501, 6511, 6521 series) with automatic probe ID recognition
- High-resolution velocity output: 0.01 m/s resolution with linearized digital signal processing and temperature-compensated algorithms
- Dual analog output options: Isolated 0–5 V DC or 4–20 mA current loop outputs, configurable per channel for integration with PLCs, SCADA, or BMS systems
- RS-232C serial interface compliant with EIA/TIA-232-F specifications; supports ASCII command protocol for remote control and data streaming
- Robust industrial enclosure (IP20-rated) with aluminum chassis and EMI-shielded internal layout for electromagnetic compatibility in electrically noisy environments
Sample Compatibility & Compliance
The KA12+ is validated for use with all KANOMAX-certified thermal anemometer probes, including stainless-steel sheathed wire probes (for ductwork), flexible micro-probes (for confined spaces), and vane-assisted probes (for high-turbulence applications). Probe selection directly determines measurable velocity range—for example, the standard 6501 probe covers 0.05–30 m/s, while the low-velocity 6521 probe extends down to 0.01 m/s. The system meets IEC 61000-4-2 (ESD immunity), IEC 61000-4-3 (radiated RF immunity), and conforms to JIS B 7551 (anemometer performance testing methods). It supports GLP-compliant operation through audit-trail-enabled software logging and satisfies documentation requirements for ISO 14644-3 cleanroom certification and ASHRAE 110 tracer gas testing protocols.
Software & Data Management
The bundled KANOMAX Anemometer Manager (v4.2+) provides full configuration, real-time visualization, and post-processing capabilities. Software features include multi-channel time-series overlay, statistical reporting (mean, min/max, standard deviation, turbulence intensity), customizable chart export (PNG, CSV, PDF), and automated report generation per ISO/IEC 17025 templates. Data files are timestamped with UTC synchronization and support metadata tagging (operator ID, location code, probe serial number). For regulated environments, optional 21 CFR Part 11 compliance modules provide electronic signature enforcement, user role-based access control, and immutable audit logs—fully compatible with FDA-submission workflows and pharmaceutical facility qualification (IQ/OQ/PQ).
Applications
- HVAC system balancing and airflow verification in commercial buildings and hospitals
- Cleanroom ISO Class 5–8 airflow uniformity and recovery time assessment
- Industrial exhaust hood face velocity validation per ANSI/AIHA Z9.5 and OSHA 1910.145
- Wind tunnel calibration and boundary layer profiling in aerodynamic research labs
- Environmental chamber airflow homogeneity mapping during product reliability testing
- Occupational hygiene surveys for local exhaust ventilation (LEV) performance audits
FAQ
Can the KA12+ measure air temperature simultaneously with velocity?
Yes—when paired with optional dual-sensor probes (e.g., model 6511-T), the system acquires both velocity and temperature (±0.5 °C accuracy) on each channel.
Is probe calibration traceable to national standards?
All KANOMAX probes shipped with the KA12+ carry NIST-traceable calibration certificates issued by A2LA-accredited laboratories.
Does the system support continuous unattended logging?
Yes—via RS-232C or analog output, the KA12+ can stream data to external dataloggers or SCADA systems for durations exceeding 30 days without interruption.
What is the maximum cable length between probe and main unit?
Standard probe cables support up to 5 m; extended-length versions (up to 30 m) are available with signal conditioning to maintain ±0.02 m/s linearity.
Can raw sensor voltage be accessed for custom algorithm development?
Yes—the RS-232C interface provides direct access to unprocessed thermistor bridge voltage outputs upon request, enabling OEM-level integration and proprietary modeling.
