Overview
The KANOMAX 6332D is a precision hot-wire anemometer transmitter engineered for real-time, high-fidelity air velocity measurement in controlled and industrial environments. Based on constant-temperature anemometry (CTA), the instrument maintains a heated sensing element at a fixed temperature differential relative to ambient airflow; changes in convective heat loss are converted linearly into electrical signals proportional to local air velocity. Unlike cup or vane anemometers, the 6332D delivers rapid response (<100 ms typical), low-flow sensitivity down to 0.1 m/s, and minimal flow disturbance—making it suitable for laminar flow characterization, HVAC commissioning, cleanroom validation, and laboratory ventilation studies. Its integrated LCD display provides immediate on-device readout without requiring external data loggers or PCs, while its modular probe architecture enables application-specific configuration across ducts, hoods, fume cabinets, and ISO-classified spaces.
Key Features
- Real-time LCD display with dual-unit capability (m/s and fpm), updated at 2 Hz for dynamic monitoring
- Switch-selectable analog output: factory-configurable between 0–5 V DC, 0–1 V DC, or 4–20 mA current loop—supporting integration with PLCs, SCADA systems, and building management systems (BMS)
- Modular probe interface compatible with ten standardized KANOMAX hot-wire probes (e.g., straight, bent, retractable, high-temperature variants), each calibrated individually and traceable to JIS Z 8000 and ISO/IEC 17025-accredited standards
- Rugged aluminum housing (IP54-rated enclosure) with EMI-shielded electronics for stable operation in electrically noisy environments
- DC 12 V ±2 V power input with reverse-polarity protection and low-power standby mode (<15 mA quiescent current)
- Multi-unit daisy-chaining capability via isolated analog outputs, enabling synchronized multi-point velocity profiling without signal degradation
Sample Compatibility & Compliance
The 6332D supports measurements in non-corrosive, particle-free airstreams within its specified operating temperature (5–40 °C) and humidity range (≤80% RH, non-condensing). It is not rated for explosive atmospheres (ATEX/IECEx), high-particulate environments (e.g., spray booths), or saturated steam lines. Probe selection determines environmental suitability: e.g., the 6332-05 stainless-steel probe operates up to 120 °C, while the 6332-08 low-turbulence probe minimizes wake interference in low-velocity laminar flows (<0.5 m/s). The device complies with EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. Calibration certificates include uncertainty budgets per ISO/IEC 17025 and are issued with NIST-traceable reference standards. For regulated facilities, the 6332D supports GLP-compliant documentation workflows when paired with KANOMAX’s optional DataLogger Pro software (v3.2+), including audit trails and electronic signature support aligned with FDA 21 CFR Part 11 principles.
Software & Data Management
While the 6332D operates autonomously via its front-panel display, optional PC-based software (KANOMAX DataLogger Pro) enables time-synchronized data acquisition from up to 32 units over RS-485 Modbus RTU or USB-to-serial interfaces. Software features include configurable sampling intervals (0.1–60 s), automatic zero-drift compensation, statistical reporting (mean, min/max, standard deviation), and export to CSV, Excel, or PDF formats compliant with ISO 14644-3 Annex B for cleanroom airflow certification. All recorded datasets retain embedded metadata: timestamp (UTC), probe ID, calibration due date, operator ID, and environmental conditions logged via optional external temperature/humidity sensor inputs.
Applications
- HVAC system balancing and TAB (Testing, Adjusting, and Balancing) per ASHRAE Guideline 1 and ISO 16813
- Cleanroom airflow uniformity mapping (ISO 14644-3, EU GMP Annex 1)
- Biological safety cabinet face velocity verification (NSF/ANSI 49)
- Industrial exhaust hood capture velocity assessment (OSHA Technical Manual Section III: Chapter 5)
- Research-grade boundary layer studies in wind tunnels and environmental chambers
- Validation of laminar flow workstations and pharmaceutical isolators
FAQ
Can the 6332D be used outdoors?
No—it is designed for indoor, conditioned environments only. Its operating temperature range (5–40 °C) and lack of weatherproofing preclude sustained outdoor deployment.
Is probe calibration included with purchase?
Each probe ships with a factory calibration certificate (NIST-traceable, valid for 12 months). Field recalibration requires KANOMAX-certified service centers or accredited third-party labs.
Does the 6332D support digital communication protocols beyond analog output?
Yes—via optional RS-485 interface (Modbus RTU slave mode), enabling integration into industrial automation networks without additional signal converters.
What maintenance is required for long-term accuracy?
Annual inspection of probe wire integrity and zero-point verification using KANOMAX’s zero-air kit (Model ZK-1) is recommended. Avoid touching or cleaning the platinum wire sensor with solvents or abrasives.
Can multiple 6332D units share a single power supply?
Yes—when powered via a regulated 12 V DC source with sufficient current capacity (≥1 A per 5 units), provided ground isolation is maintained to prevent common-mode noise coupling.
