Overview
The KANOMAX 6720-DP Grid is a high-precision, multi-parameter environmental monitoring instrument engineered for validation and routine surveillance of controlled pharmaceutical environments—including ISO Class 5–8 cleanrooms, laminar airflow hoods, biological safety cabinets (BSCs), and HVAC supply/exhaust ducts. It operates on dual-sensing principles: pitot tube-based dynamic pressure measurement for point-velocity profiling and a 16-point grid sensor array for spatially resolved face velocity mapping—enabling compliant verification of uniformity per ISO 14644-3 and EU GMP Annex 1 requirements. Integrated differential pressure sensing supports simultaneous monitoring of room-to-room or cabinet-to-ambient pressure differentials critical for containment integrity. Designed in Japan with metrological traceability to JIS Z 8000 and NIST-compatible calibration protocols, the device meets the foundational accuracy and repeatability demands of GLP- and GMP-regulated operations.
Key Features
- 4.3-inch full-color capacitive touchscreen interface with intuitive icon-driven navigation—optimized for gloved operation in cleanroom settings
- Simultaneous real-time acquisition of air velocity (Pitot + grid), volumetric flow rate, and differential pressure—reducing measurement cycle time by up to 60% versus single-parameter instruments
- Dual-configuration capability: interchangeable use of stainless-steel pitot tubes (for duct/point measurements) and a rigid 4×4 grid probe (for HEPA filter face scanning per ISO 14644-3 Annex B.4)
- Bluetooth 5.0 wireless connectivity enabling secure pairing with iOS/Android devices running the official KANOMAX AirFlow Manager app—supporting remote configuration, live data streaming, and audit-ready timestamped export
- On-device storage of 8,000 measurement records with embedded metadata (date/time, operator ID, location tag, sensor type); mobile app extends capacity to 10,000 records with optional cloud backup
- Configurable K-factor compensation for pitot tube calibration across varied duct geometries and fluid densities—essential for non-standard HVAC installations
- Auto-power management: enters low-power sleep mode after 5 minutes of inactivity; resumes instantly upon touch or Bluetooth wake signal
Sample Compatibility & Compliance
The 6720-DP Grid is validated for use with standard cleanroom-grade accessories including telescopic extension poles (up to 2.5 m), thermal-printed label rolls (via optional Bluetooth printer), and sterile-compatible probe housings. Its measurement uncertainty profile satisfies the performance criteria outlined in ISO 14644-3 (cleanroom testing), ISO 8573-1 (compressed air quality), and ASHRAE Standard 111 (field measurements). The device’s firmware supports configurable pass/fail thresholds aligned with EU GMP Annex 1 §4.37 (airflow velocity ≥0.45 m/s ±20% at filter face) and USP (microbial control via unidirectional airflow verification). All stored data include immutable timestamps, operator identifiers, and sensor serial numbers—enabling compliance with FDA 21 CFR Part 11 when used with validated app configurations.
Software & Data Management
The KANOMAX AirFlow Manager software (Windows/macOS) and companion mobile app provide full lifecycle data governance. Users can generate PDF reports with embedded graphs, annotated test locations, and pass/fail summaries—exportable in CSV, PDF, or XML formats for LIMS integration. Audit trail functionality logs all configuration changes, record deletions, and calibration events with user attribution and UTC timestamps. Data encryption (AES-256) is applied both in transit (Bluetooth LE Secure Connections) and at rest (on-device flash memory). Optional USB-C data dump enables offline transfer to validated QA systems without network dependency.
Applications
- Pre- and post-certification testing of unidirectional airflow systems in aseptic processing isolators and RABS
- HEPA filter face velocity mapping and uniformity assessment across ISO 14644-3 specified grid points
- Duct traverse surveys for HVAC balancing and airflow volume verification (using pitot-static method per ISO 14644-3 Annex C)
- Pressure cascade validation between classified zones (e.g., Grade C to Grade A anterooms)
- Root-cause analysis of airflow turbulence or recirculation zones via sequential grid scans
- Periodic requalification per ICH Q5A and EU GMP Annex 15 requirements
FAQ
Does the 6720-DP Grid support calibration traceability to national standards?
Yes—each unit ships with a factory calibration certificate traceable to JCSS-accredited laboratories (JIS Z 8000-1), and optional UKAS or NIST-traceable recalibration services are available through authorized KANOMAX service centers.
Can the grid sensor be sterilized for use inside isolators?
The grid probe housing is constructed from autoclavable 316L stainless steel and polyetherimide (PEI); it withstands steam sterilization at 121 °C for 20 minutes—validated per ISO 14971 risk management protocols.
Is differential pressure measurement affected by ambient temperature drift?
The integrated piezoresistive ΔP sensor features active temperature compensation (0–60 °C range) and achieves ±0.25 Pa zero stability over 8-hour continuous operation—verified per IEC 61260-1 Class 1 specifications.
How is data integrity ensured during Bluetooth transmission?
All wireless sessions employ Bluetooth LE Secure Connections with LE Secure Pairing (Just Works model), and payload encryption prevents interception or replay attacks—meeting IEC 62304 Software Safety Class B requirements.
What is the recommended recalibration interval under GMP conditions?
Per KANOMAX technical guidance and EU GMP Annex 15 §5.2.3, annual recalibration is required; however, users must perform operational qualification (OQ) checks before each critical test campaign using certified reference standards.
