Overview
The KANOMAX 65 Series Digital Hot-Wire Anemometer is a multi-parameter environmental monitoring instrument engineered for precision measurement of air velocity, volumetric flow rate, temperature, relative humidity, and differential pressure in HVAC commissioning, cleanroom validation, industrial hygiene surveys, and laboratory ventilation assessments. Utilizing constant-temperature anemometry (CTA), the system maintains a heated sensing element at a stable thermal offset above ambient—enabling real-time detection of convective heat loss proportional to local airflow velocity. This principle ensures high sensitivity across low-to-moderate flow regimes (0.01–30 m/s, dependent on probe configuration) while minimizing turbulence-induced measurement drift. Unlike cup or vane anemometers, the hot-wire design offers rapid response time (<0.5 s), directional independence, and minimal flow disturbance—critical for laminar flow characterization and duct traverse applications.
Key Features
- Simultaneous acquisition of air velocity, temperature, humidity, and differential pressure—reducing field instrumentation redundancy and calibration overhead.
- Eight interchangeable probe options—including straight, bent, telescopic, and thermal-hygrometric variants—each calibrated individually and auto-recognized via probe ID circuitry.
- Onboard calculation engine supports customizable duct geometry input (rectangular, circular, oval) with automatic cross-sectional area derivation and volumetric flow (m³/h or CFM) computation per ISO 16813 and ASHRAE Guideline 12.
- Real-time statistical functions: running average, min/max hold, and standard deviation—enabling compliance with EN 13725 odor concentration sampling protocols and ISO 14644-3 cleanroom uniformity assessments.
- Rugged handheld form factor (IP42-rated enclosure), battery-operated portability (up to 12 h continuous use), and dual power mode (AA batteries or optional AC adapter) for extended field deployment.
Sample Compatibility & Compliance
The 65 Ser accommodates diverse sampling environments—from unidirectional airflow in ISO Class 5 laminar flow hoods to turbulent return-air grilles in commercial HVAC systems. Its −20 to +70 °C operating range and 0–100 %RH tolerance permit use in refrigerated storage rooms, steam sterilizer exhaust ducts, and outdoor rooftop unit inspections. All probes comply with IEC 61000-4 electromagnetic immunity standards. Measurement accuracy meets ASTM D1072 (air velocity in ducts) and ISO 7726 (ergonomic assessment of thermal environments). For regulated facilities, data logging supports audit-ready timestamped records compatible with GLP/GMP documentation workflows when paired with KANOMAX’s optional validation package.
Software & Data Management
Data export occurs via USB interface to KANOMAX’s proprietary PC software (Windows-compatible), supporting CSV and Excel-native formats for integration into LIMS or building management systems. The software enables post-processing of stored datasets—including time-series trending, spatial averaging across multi-point traverses, and deviation mapping against setpoints. Audit trail functionality logs user actions, parameter changes, and calibration events—addressing FDA 21 CFR Part 11 requirements for electronic record integrity where configured with password-protected user roles. No cloud dependency; all processing remains local to ensure data sovereignty.
Applications
- HVAC system balancing and TAB (Testing, Adjusting, Balancing) per NEBB and AABC standards.
- Cleanroom classification (ISO 14644-1/2) and airflow visualization during smoke studies.
- Occupational exposure assessment per OSHA Technical Manual Chapter 2 and NIOSH Manual of Analytical Methods (NMAM) Method 0500.
- Pharmaceutical facility environmental monitoring (EM) programs requiring documented airflow verification in Grade A/B zones.
- Academic and industrial aerodynamics labs conducting boundary layer profiling or fan performance characterization.
FAQ
Does the 65 Ser require annual recalibration?
Yes—KANOMAX recommends traceable recalibration every 12 months or after any mechanical shock, extreme environmental exposure, or observed measurement drift exceeding specification limits.
Can the device calculate airflow in non-rectangular ducts?
Yes—users input internal dimensions for circular, oval, or irregular cross-sections; the instrument applies geometric algorithms per ISO 16813 Annex B to compute effective area and derive volumetric flow.
Is probe interchangeability limited to KANOMAX-branded sensors?
Only KANOMAX-certified 65 Ser series probes are supported; third-party probes lack embedded calibration coefficients and will not initialize.
What is the maximum sampling interval for continuous logging?
The internal memory supports up to 20,000 records at user-selectable intervals from 1 second to 60 minutes.
Does the analog output support 4–20 mA signal conversion?
No—the 0–1 V analog output is fixed-range and requires external signal conditioning for 4–20 mA integration.
