Overview
The Kanomax 6332D is a precision-engineered thermal anemometer transmitter designed for continuous, high-reproducibility wind velocity monitoring in controlled and industrial environments. Utilizing constant-temperature anemometry (CTA) principle, the device measures convective heat loss from a heated sensing element—typically a fine-wire or thin-film resistor—to determine airflow velocity with minimal thermal inertia. Its robust architecture supports stable operation across dynamic air streams encountered in HVAC commissioning, cleanroom qualification, laminar flow hood validation, and environmental chamber performance verification. Unlike cup or vane anemometers, the 6332D delivers true low-velocity sensitivity down to 0.1 m/s while maintaining linearity and repeatability up to 50 m/s—making it suitable for both laminar and turbulent flow characterization where spatial resolution and temporal response are critical.
Key Features
- Thermal sensing principle ensures high sensitivity at low velocities (0.1 m/s threshold) without mechanical wear or rotational inertia limitations
- Interchangeable probe compatibility with Kanomax’s 6332-series sensor heads—including straight, bent, and retractable configurations—for flexible installation in ducts, grilles, and confined spaces
- Integrated backlit LCD display provides real-time wind speed readout with selectable units (m/s, ft/min, knots, km/h) and instantaneous min/max/avg tracking
- Configurable analog output interface: user-selectable via internal DIP switches between 0–5 V DC, 0–1 V DC, or 4–20 mA current loop outputs—enabling seamless integration with PLCs, SCADA systems, and building management controllers
- Compact, IP54-rated housing (128 × 78 × 30 mm; 320 g) optimized for panel mounting or surface installation in laboratory and industrial enclosures
- Stable calibration traceability maintained over extended operational periods—validated per ISO/IEC 17025-accredited procedures using NIST-traceable wind tunnel references
Sample Compatibility & Compliance
The 6332D is compatible with all Kanomax 6332-series thermal probes, including models with stainless-steel sheaths (e.g., 6332-01, 6332-02) rated for particulate-laden or mildly corrosive airstreams. It operates reliably within ambient temperatures of 5–40 °C and relative humidity up to 80% non-condensing. While not intrinsically safe, the unit complies with CE marking requirements under EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. Its analog output architecture supports compliance with industrial control system standards such as ISA-50.00.01 (analog signaling) and facilitates alignment with HVAC-related ASHRAE Guideline 12 and ISO 14644-3 cleanroom testing protocols when paired with validated probe assemblies.
Software & Data Management
The 6332D operates as a standalone analog transmitter and does not require proprietary software for basic functionality. However, when integrated into multi-channel monitoring networks—via optional Kanomax data loggers (e.g., 3830 series) or third-party DAQ systems—it supports time-synchronized acquisition, trend logging, and alarm triggering based on user-defined velocity thresholds. All analog output signals are linear and calibrated per manufacturer specifications, enabling direct interpretation without curve-fitting. For GxP-regulated applications, external data acquisition platforms configured with audit trail, electronic signature, and 21 CFR Part 11-compliant security controls may be employed to meet GLP/GMP documentation requirements.
Applications
- HVAC system balancing and air change rate verification in pharmaceutical manufacturing suites and hospital isolation rooms

- Real-time monitoring of exhaust hoods, fume cabinets, and biosafety cabinets per ANSI/ASHRAE 110 and EN 14175
- Environmental chamber airflow uniformity mapping during temperature/humidity stability studies
- Industrial ventilation assessment in semiconductor fabrication facilities and battery dry rooms
- Research-grade boundary layer profiling in aerodynamic test benches and wind tunnel calibration zones
FAQ
Is the 6332D suitable for outdoor use?
No—the device is rated for indoor use only, with an operating temperature range limited to 5–40 °C and no ingress protection beyond IP54. Outdoor deployment requires environmental enclosures and thermal stabilization.
Can multiple 6332D units be synchronized for spatial velocity mapping?
Yes—units can be daisy-chained via shared power and ground lines, and their analog outputs referenced to a common data acquisition system for time-aligned multi-point measurement.
Does the 6332D support digital communication protocols such as Modbus or BACnet?
No—it provides analog-only output (voltage or current). Digital integration requires external signal conditioning or gateway hardware.
What calibration documentation is provided with the instrument?
Each unit ships with a factory calibration certificate indicating reference conditions, uncertainty budget, and traceability to national standards; optional ISO/IEC 17025-accredited calibration is available upon request.
How often should the sensor probe be recalibrated?
Annual recalibration is recommended for critical applications; more frequent verification (e.g., quarterly) is advised in high-particulate or high-humidity environments where probe contamination may affect thermal response.
