Kanomax 6720-DP Grid Multi-Parameter Air Velocity & Differential Pressure Meter for Cleanroom Certification

Overview

The Kanomax 6720-DP Grid is a high-precision, multi-parameter environmental monitoring instrument engineered specifically for cleanroom commissioning, qualification, and routine performance verification per ISO 14644-3, ISO 14644-4, and EU GMP Annex 1 requirements. Unlike conventional single-point anemometers, this system integrates three independent measurement modalities—pitot tube-based air velocity sensing, a 16-point grid array probe for planar velocity profiling, and a high-resolution differential pressure transducer—within a unified, field-deployable architecture. Its core measurement principle relies on dynamic pressure differentials across calibrated pitot elements (for point velocity), spatially distributed thermal anemometric sensors (for uniformity mapping), and piezoresistive silicon diaphragm technology (for stable ΔP quantification). The device is not a general-purpose airflow meter; it is purpose-built for the stringent repeatability, traceability, and spatial resolution demands of ISO Class 3–8 cleanroom certification, laminar flow bench validation, and HVAC balancing in pharmaceutical, biotech, and microelectronics manufacturing environments.

Key Features

• Simultaneous real-time acquisition of air velocity (0.15–40 m/s via pitot tube; 0.15–15 m/s via 4×4 grid array), volumetric airflow (40–4300 m³/h), and differential pressure (−2500 to +2500 Pa) — eliminating sequential instrument swaps and inter-device calibration drift.
• 4.3-inch full-color capacitive touchscreen interface with intuitive icon-driven navigation, on-screen K-factor adjustment, and embedded clock-synchronized logging — optimized for glove-compatible operation in controlled environments.
• Dual-mode data persistence: 8,000 measurement sets stored internally with timestamp, location tag, and operator ID; up to 10,000 records synchronized to the Kanomax SmartLink mobile application (iOS/Android) via Bluetooth 4.2.
• Field-configurable reporting: Direct Bluetooth printing to compatible thermal printers or USB export of CSV/Excel-formatted datasets compliant with 21 CFR Part 11 audit trail prerequisites (when used with validated software configuration).
• Extended operational endurance: 14-hour continuous runtime on four standard AA alkaline cells; auto-sleep mode activates after 5 minutes of inactivity to preserve battery integrity during multi-point surveys.
• Ruggedized industrial design: IP54-rated enclosure, integrated carrying handle, and modular probe interface supporting optional telescopic mast (up to 3.2 m), AC adapter, and certified NIST-traceable calibration kits.

Sample Compatibility & Compliance

The 6720-DP Grid is validated for use with standard cleanroom airflow configurations including unidirectional (laminar) supply diffusers, non-unidirectional (turbulent) ceiling grids, and terminal HEPA/ULPA filter banks. Its grid array probe enables ISO 14644-3 Annex B-compliant uniformity mapping across ≥0.3 m² test planes, while the pitot tube supports ISO 14644-4 Section 7.3.2.1 velocity profile measurements at duct cross-sections. All sensor modules are factory-calibrated against NIST-traceable reference standards, with calibration certificates issued per ISO/IEC 17025 requirements. The instrument meets electromagnetic compatibility (EMC) criteria per IEC 61326-1 and operates within environmental limits defined by ISO 14644-2 for in-situ monitoring: 0–60 °C ambient temperature (non-condensing), 0–100 %RH. It supports GLP/GMP-aligned workflows through configurable user access levels, electronic signature capability (via companion software), and immutable log file generation.

Software & Data Management

Kanomax SmartLink software (Windows/macOS/iOS/Android) provides full post-processing functionality: automated ISO uniformity index calculation (U-value, CV%), spatial heatmap generation, delta-P trending over time, and deviation flagging against user-defined acceptance thresholds (e.g., ±20% velocity variation per ISO 14644-3). Raw datasets include metadata such as probe type, K-factor, ambient T/RH, operator ID, and GPS-tagged location (mobile only). Export formats include CSV (for LIMS integration), PDF reports with embedded calibration status, and XML files compatible with enterprise QA systems. Audit trails record all parameter changes, data deletions, and firmware updates — satisfying FDA 21 CFR Part 11 Subpart B requirements when deployed under documented SOPs.

Applications

• Cleanroom classification and re-certification per ISO 14644-1 and EU GMP Annex 1 (air velocity mapping, uniformity assessment, recovery testing).
• Laminar flow cabinet and biosafety cabinet (BSC) validation per NSF/ANSI 49 and EN 12469.
• HVAC system balancing, duct traverse studies, and filter bank leak testing support (when paired with aerosol photometers).
• Pharmaceutical facility qualification (IQ/OQ/PQ) where differential pressure monitoring across gowning rooms, airlocks, and production suites is mandated.
• Microelectronics clean manufacturing line monitoring, including tool exhaust verification and mini-environment stability checks.

FAQ

Does the 6720-DP Grid meet ISO 14644-3 requirements for cleanroom airflow uniformity testing?
Yes — its 4×4 grid array probe enables compliant 16-point planar velocity sampling across defined test areas, with built-in calculation of coefficient of variation (CV%) and mean velocity per ISO 14644-3 Annex B.
Can measurement data be electronically signed and archived for FDA-regulated environments?
When used with Kanomax SmartLink v3.2+ and configured under a validated IT environment, the system supports ALCOA+ principles: attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available — fulfilling core 21 CFR Part 11 expectations.
Is the pitot tube and grid array probe supplied with NIST-traceable calibration documentation?
Each probe is shipped with a manufacturer’s calibration certificate referencing NIST-traceable standards; optional third-party accredited calibration (ISO/IEC 17025) is available upon request.
What is the recommended recalibration interval for routine GMP compliance?
Kanomax recommends annual recalibration; however, the interval may be extended to 24 months based on risk assessment, historical performance data, and internal SOPs aligned with ISO/IEC 17025 Clause 7.8.5.
Can the device operate continuously during extended cleanroom shutdown surveys?
Yes — with fresh AA batteries, the unit sustains >14 hours of active logging; low-power sleep mode extends standby time to >72 hours without data loss.
