KANOMAX Model 6006 Thermal Anemometer for Cleanroom Air Velocity Monitoring

Overview

The KANOMAX Model 6006 Thermal Anemometer is a compact, handheld instrument engineered for precise and repeatable air velocity measurements in controlled environments—particularly ISO Class 5–8 cleanrooms, laminar flow hoods, HVAC validation zones, and pharmaceutical grade A/B/C/D areas. It operates on constant-temperature anemometry (CTA) principles: a heated thermistor sensor element is maintained at a fixed temperature differential above ambient; airflow convective cooling alters the required heating current, which is linearly correlated to local air velocity. This method delivers stable, low-inertia response with no moving parts—critical for non-intrusive monitoring of unidirectional airflow systems where mechanical disturbance must be avoided. Unlike cup or vane anemometers, the 6006 provides true instantaneous readings without angular dependency, enabling accurate profiling across filter face velocities, supply diffusers, and return grilles per ISO 14644-3 and EU GMP Annex 1 requirements.

Key Features

• Simultaneous dual-parameter measurement: real-time air velocity (0.01–20.0 m/s) and ambient temperature (−20 to +70 °C) using a single integrated probe
• Interchangeable probe design compatible with optional KANOMAX accessories—including extended-length probes (e.g., 300 mm telescopic shaft) and multi-point array adapters for grid-based mapping
• Ergonomic, palm-sized housing (60 × 120 × 34 mm) with tactile button layout optimized for gloved operation in cleanroom suits
• High-resolution display with backlight for low-illumination environments; automatic data hold and max/min/avg functions support manual validation protocols
• Low-power architecture: continuous operation >20 hours on four standard AA alkaline cells; no external power supply or charging circuitry required
• Ruggedized ABS enclosure rated IP54 for dust resistance and limited moisture exposure—suitable for use in gowning rooms and adjacent technical corridors

Sample Compatibility & Compliance

The Model 6006 is validated for use in non-corrosive, particle-free airstreams typical of HEPA- and ULPA-filtered clean environments. It is not intended for high-humidity condensing conditions (>85% RH), abrasive particulate-laden ductwork, or explosive atmospheres (ATEX/IECEx). Its measurement methodology conforms to the fundamental principles outlined in ISO 7726 (Ergonomics of the thermal environment — Instruments for measuring physical quantities) and supports traceable calibration against NIST-traceable reference standards. While the device itself does not carry CE marking for medical devices or IEC 61000-4 immunity certification, its performance characteristics meet the functional expectations for routine qualification and periodic verification under ISO 14644-1/2/3, FDA Guidance for Industry: Sterile Drug Products Produced by Aseptic Processing, and EU GMP Annex 1 (2022 revision) Section 4.36–4.41 on airflow visualization and uniformity testing.

Software & Data Management

The Model 6006 operates as a standalone field instrument with no embedded memory or USB interface. All data recording is manual—designed intentionally to minimize contamination risk and eliminate software validation burden in regulated settings. Users document readings directly into paper-based or electronic batch records (e.g., LIMS or MES forms) compliant with 21 CFR Part 11 when paired with audit-trail-enabled platforms. Optional KANOMAX PC software (e.g., KANOTHERM v3.x) may be used offline with compatible data loggers, but the 6006 itself requires no firmware updates, cybersecurity controls, or network connectivity—reducing IT validation scope during GxP audits. Calibration certificates include uncertainty budgets aligned with ISO/IEC 17025-accredited laboratories.

Applications

• Filter face velocity mapping per ISO 14644-3 Clause 8.2.2 and EU GMP Annex 1 Paragraph 4.39
• Verification of unidirectional airflow uniformity across critical work zones (e.g., filling lines, isolators)
• Baseline characterization and requalification of HVAC terminal units during commissioning and periodic review
• Troubleshooting laminar flow integrity issues—including turbulence detection near obstructions or personnel movement
• Supporting smoke visualization studies by providing quantitative velocity context alongside qualitative airflow patterns
• Environmental monitoring program (EMP) execution in biotech manufacturing, medical device packaging, and semiconductor fabrication support areas

FAQ

Does the Model 6006 support data logging or Bluetooth transmission?
No. It is a dedicated readout-only instrument with no internal memory, wireless interface, or serial output—by design to maintain simplicity, reliability, and regulatory acceptability in Grade A/B environments.
Can the probe be sterilized or autoclaved?
No. The sensor assembly is not rated for steam sterilization or chemical immersion. Wipe disinfection with 70% isopropyl alcohol is permitted between uses.
Is the ±5% accuracy specification valid across the full 0.01–20.0 m/s range?
Yes—however, optimal repeatability (95% of cleanroom application scenarios per ISO 14644-3 Annex B.
What calibration interval is recommended for GMP-regulated use?
Annual calibration is standard; however, user risk assessment may justify semi-annual intervals for high-criticality applications or after mechanical shock events.
Are replacement probes and calibration services available globally?
Yes. KANOMAX maintains authorized service centers in North America, EMEA, and APAC regions offering probe recalibration, NIST-traceable certificates, and OEM spare parts fulfillment under controlled distribution channels.
