Overview
The KANOMAX Digital Hot-Wire Anemometer is a precision-engineered environmental monitoring instrument designed for reliable, real-time measurement of air velocity, volumetric airflow, temperature, relative humidity, and differential pressure in HVAC systems, cleanrooms, laboratories, and industrial ventilation applications. Utilizing constant-temperature anemometry (CTA), the device maintains a heated sensing element at a fixed temperature above ambient; convective cooling by airflow alters the electrical resistance of the fine platinum or tungsten wire, enabling highly responsive and repeatable velocity quantification. Unlike cup or vane anemometers, thermal anemometers offer superior low-flow sensitivity and rapid transient response—critical for laminar flow characterization, duct balancing, and ISO 14644-compliant cleanroom certification. Its modular architecture supports field-reconfigurable probe configurations without recalibration, ensuring metrological continuity across diverse measurement geometries.
Key Features
- Simultaneous multi-parameter acquisition: air velocity (m/s), volumetric airflow (m³/h or CFM), ambient temperature (°C/°F), relative humidity (%RH), and differential pressure (Pa or inH₂O)
- Eight standardized, plug-and-play probe options—including straight, bent, retractable, and extended-length variants—enabling adaptation to ducts, grilles, hoods, and confined spaces
- On-device cross-sectional area entry with shape selection (rectangular, circular, oval) and dimensional input to compute volumetric flow automatically
- Real-time data hold function with peak-hold and valley-hold modes for capturing transient events
- Integrated statistical engine calculating mean, maximum, minimum, and standard deviation over user-defined sampling intervals
- Rugged, IP54-rated housing with backlit LCD display optimized for low-light and high-glare environments
- Internal non-volatile memory storing up to 20,000 timestamped records with automatic time/date stamping
Sample Compatibility & Compliance
The instrument is validated for use across standard indoor air environments per ISO 7726 (Ergonomics of the thermal environment – Instruments for measuring physical quantities) and conforms to IEC 61000-4 electromagnetic compatibility requirements. Probe interchangeability follows KANOMAX’s proprietary mechanical and electrical interface standard, ensuring traceable calibration continuity when switching between probe types. All measurements comply with ASHRAE Guideline 12–2020 (Managing the Risk of Legionellosis Associated with Building Water Systems) for HVAC commissioning and routine verification. The device supports GLP-aligned documentation practices via exportable CSV files containing raw sensor values, metadata, and operator ID fields—facilitating audit readiness under ISO/IEC 17025 and FDA 21 CFR Part 11 where electronic records are employed.
Software & Data Management
Data retrieval is performed via USB-C interface using KANOMAX’s Windows-compatible PC software (v3.2+), which provides synchronized time-stamped waveform visualization, customizable report generation (PDF/Excel), and batch export functionality. The software enforces role-based access control (administrator/operator modes), audit trail logging for all configuration changes, and digital signature capability for final report sign-off. Raw datasets retain full resolution (0.01 m/s velocity steps, 0.1 °C temperature, 0.1 %RH humidity) without interpolation or compression. Export formats include ANSI-compliant CSV with header definitions aligned to ASTM E177 (Standard Practice for Use of the Terms Precision and Bias in ASTM Test Methods).
Applications
- HVAC system commissioning and TAB (Testing, Adjusting, Balancing) per NEBB and AABC standards
- Cleanroom airflow uniformity mapping and ISO 14644-3 Class verification
- Fume hood face velocity validation per ANSI/ASHRAE 110 and EN 14175
- Industrial exhaust stack profiling and local exhaust ventilation (LEV) performance audits
- Indoor air quality (IAQ) baseline surveys supporting LEED EQ Credit 1 compliance
- Research-grade boundary layer studies in wind tunnels and environmental chambers
FAQ
Does the instrument require annual recalibration?
Yes. KANOMAX recommends traceable recalibration every 12 months against NIST-traceable standards, particularly after probe replacement or exposure to condensation, particulate loading, or mechanical shock.
Can the device calculate airflow in irregular duct shapes?
It supports only predefined geometries (rectangle, circle, oval); irregular profiles must be approximated via segmentation or external CFD-assisted modeling.
Is the memory retained during battery replacement?
Yes—data persistence is maintained via EEPROM; no loss occurs during power interruption or battery swap.
Are calibration certificates included with purchase?
A factory calibration certificate (traceable to JCSS, Japan) is supplied; optional UKAS or NIST-traceable certificates are available upon request.
What is the typical probe service life under normal laboratory use?
Standard hot-wire probes exhibit ≥24 months of stable performance when operated within specified temperature/humidity limits and protected from oil mist, corrosive gases, or mechanical abrasion.
