Overview
The Kanomax 6720-DP is a high-precision, multi-parameter environmental monitoring instrument engineered for quantitative validation of containment performance in biosafety cabinets (BSCs), laminar flow hoods, and cleanroom ventilation systems. It operates on the fundamental principles of pitot-static pressure differential measurement—applying Bernoulli’s equation to derive air velocity from dynamic and static pressure differentials—and integrates simultaneous real-time acquisition of face velocity, volumetric airflow, and micro-differential pressure across critical barriers. Designed in accordance with ISO 14644-3, NSF/ANSI 49, and EN 12464-1 requirements for laboratory safety infrastructure verification, the 6720-DP delivers traceable, repeatable measurements essential for GLP-compliant facility qualification, routine maintenance audits, and regulatory readiness assessments.
Key Features
- Simultaneous triple-parameter measurement: air velocity (via integrated pitot tube or optional velocity matrix), volumetric airflow (calculated from cross-sectional area and mean velocity), and micro-differential pressure (±2500 Pa range, 0.001 Pa resolution)
- 4.3-inch full-color capacitive touchscreen interface with intuitive icon-driven navigation and real-time graphical trend display
- Bluetooth 5.0 wireless connectivity enabling bidirectional data exchange with iOS/Android mobile devices running the official Kanomax SmartLog app
- On-device storage of up to 8,000 measurement records; companion app supports 10,000 records with timestamp, location tagging (GPS), and customizable test templates
- Configurable K-factor compensation for pitot tube calibration correction—critical for maintaining accuracy across varying duct geometries and flow profiles
- Extended operational endurance: ~14 hours continuous use on four standard AA alkaline batteries; auto-sleep mode activates after 5 minutes of inactivity to conserve power
- Robust industrial housing (IP54-rated enclosure) with ergonomic handgrip and integrated mounting points for tripod or bracket attachment
Sample Compatibility & Compliance
The 6720-DP is validated for use across Class I, II, and III biosafety cabinets per NSF/ANSI 49-2022 Annex D protocols, including inward face velocity mapping at multiple points along the sash opening, inflow velocity profiling, and exhaust filter bypass differential pressure verification. Its low-flow sensitivity (0.15 m/s detection limit) and high-resolution dP sensing (0.001 Pa) meet the stringent requirements of ISO 14644-3:2019 Annex B for localized airflow characterization. The instrument complies with IEC 61000-4 electromagnetic compatibility standards and carries CE marking under the EU Measuring Instruments Directive (MID) for legal metrology applications where applicable. All firmware and calibration data are stored with immutable timestamps and user-accessible audit logs—supporting 21 CFR Part 11-aligned electronic record integrity when used in regulated pharmaceutical or clinical laboratory environments.
Software & Data Management
Kanomax SmartLog software provides comprehensive post-acquisition analysis, report generation, and database synchronization. Raw datasets include metadata such as operator ID, cabinet model, test date/time, ambient temperature/humidity, and probe configuration. Export formats include CSV, PDF (with embedded signature fields), and XML for LIMS integration. The software enforces role-based access control and supports digital signature workflows compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Calibration certificates—traceable to NMIJ (National Metrology Institute of Japan)—are digitally embedded and version-controlled within each device’s firmware.
Applications
- Face velocity verification and uniformity mapping of biosafety cabinet work openings per NSF/ANSI 49 Section 6.3.1
- Differential pressure monitoring across anterooms, pass-through chambers, and isolation suites to maintain directional airflow integrity
- Volumetric airflow balancing in HVAC terminal units and fume hood exhaust systems
- Validation of laminar airflow velocity profiles in ISO Class 5–8 cleanrooms per ISO 14644-3 Annex C
- Commissioning and periodic requalification of containment enclosures in GMP manufacturing facilities (e.g., sterile drug filling lines)
- Academic and clinical lab biosafety program documentation for institutional biosafety committee (IBC) submissions
FAQ
What calibration standards does the 6720-DP support?
The unit is factory-calibrated against NMIJ-traceable reference standards for velocity (NIST SRM 1550b), differential pressure (Fluke 754), and temperature/humidity (Rotronic HygroGen2). Field recalibration requires certified service centers authorized by Kanomax Japan.
Can the 6720-DP be used for ISO 14644-1 particle counter correlation studies?
While not a particle counter, its precise airflow quantification enables calculation of air change rates (ACH) and filtration efficiency estimates—key inputs for interpreting concurrent particle concentration data per ISO 14644-1 Annex F.
Is Bluetooth data transmission encrypted?
Yes—AES-128 encryption is applied during all BLE packet exchanges between the device and SmartLog app, satisfying IT security policies in regulated institutions.
Does the instrument support custom averaging intervals for unstable flows?
Yes—users may configure time-weighted averaging windows from 1 second to 60 seconds per measurement point, optimizing repeatability in turbulent or pulsating airflow conditions.
How is compliance with FDA 21 CFR Part 11 ensured?
SmartLog implements electronic signatures, audit trails with immutable timestamps, and permission-level access controls—fully documented in the system validation package (IQ/OQ/PQ protocols available upon request).
