Overview
The KANOMAX Model 6720-DP is a high-precision handheld differential pressure meter engineered for quantitative airflow and static pressure diagnostics in controlled environments. It operates on the principle of piezoresistive pressure transduction, delivering traceable, stable measurements across a wide dynamic range from –2500 to +2500 Pa. Designed specifically for HVAC commissioning, biosafety cabinet certification (per NSF/ANSI 49 and EN 12469), cleanroom validation (ISO 14644-3), and fan performance testing, the instrument integrates dual-mode sensing architecture—supporting both direct differential pressure measurement via flexible tubing and indirect air velocity derivation using calibrated Pitot tubes or multi-point velocity matrices. Its 0.01 accuracy class reflects compliance with IEC 61260-1:2014 Class 1 tolerances for pressure instrumentation used in GLP and GMP-regulated facilities.
Key Features
- 4.3-inch full-color resistive touchscreen interface with intuitive icon-driven navigation and real-time graphical trend display
- Dual-sensor capability: simultaneous differential pressure and derived air velocity measurement without hardware reconfiguration
- Bluetooth 4.2 wireless connectivity enabling secure, low-latency data streaming to iOS/Android devices running the official KANOMAX FieldLink™ app
- On-device statistical processing: automatic calculation and logging of max/min/average/cumulative values per test session
- K-factor calibration adjustment for system-specific compensation of duct geometry, probe alignment, and fluid compressibility effects
- Low-power architecture: 14-hour continuous operation on four standard AA alkaline cells; auto-sleep mode activates after 5 minutes of inactivity
- Robust mechanical design: IP54-rated enclosure, shock-absorbing rubberized housing, and ergonomic grip optimized for one-handed field use
Sample Compatibility & Compliance
The 6720-DP is validated exclusively for gaseous media under non-condensing conditions, making it suitable for dry air, nitrogen, and other non-corrosive, non-particulate-laden process gases. It meets the environmental operating constraints defined in ISO 9001:2015 Clause 7.1.5 for monitoring and measuring resources. Its pressure transducer conforms to EN 61326-1:2013 for electromagnetic compatibility in industrial settings and carries CE marking under the EU Measuring Instruments Directive (MID) Annex MI-005 for differential pressure instruments. For regulated applications—including FDA 21 CFR Part 11-compliant HVAC validation—the device supports audit-trail-enabled data export (CSV/TXT) and time-stamped records with user-defined ID fields.
Software & Data Management
The KANOMAX FieldLink™ mobile application provides full remote control, including parameter configuration, real-time data visualization, and post-test analysis. All stored datasets (up to 10,000 entries per device profile) retain metadata such as timestamp, ambient temperature, battery level, and operator ID. Instrument-side storage (8,000 records) uses non-volatile flash memory with cyclic overwrite protection. Data export options include USB mass storage mode, Bluetooth printing to certified thermal printers (e.g., Zebra ZQ520), and encrypted cloud upload via optional KANOMAX CloudSync™ gateway. Firmware updates are delivered over-the-air through the app, ensuring long-term alignment with evolving industry standards.
Applications
- Biosafety cabinet face velocity mapping and alarm threshold verification per NSF/ANSI 49 Section 6.3.2
- Cleanroom differential pressure cascade monitoring during ISO 14644-3 qualification protocols
- HVAC duct static pressure profiling for balancing and fault isolation
- Fan curve characterization in laboratory fume hood systems
- Room pressurization integrity testing in pharmaceutical isolators and aseptic processing suites
- Exhaust stack flow rate estimation using Pitot traverse methodology (ASTM D2513)
FAQ
What pressure standards does the 6720-DP reference against?
It measures differential pressure relative to ambient atmospheric pressure using an internal dual-diaphragm transducer; no external reference port or zeroing routine is required for standard applications.
Can the instrument be used for liquid pressure measurement?
No—its sensor and wetted materials are rated only for clean, dry gases; exposure to liquids or condensate will damage the transducer.
Is NIST-traceable calibration documentation available?
Yes; factory calibration certificates (including as-found/as-left data and uncertainty budgets) are provided with each unit and may be extended through KANOMAX-accredited service centers.
Does the device support automated report generation?
FieldLink™ enables customizable PDF report templates with embedded charts, pass/fail indicators, and regulatory header blocks—exportable directly from the mobile app.
How is data integrity ensured during Bluetooth transmission?
All wireless sessions employ AES-128 encryption and packet-level CRC32 checksum validation to prevent corruption or unauthorized interception.
