Overview
The KANOMAX Model 6720-DP is a precision-engineered handheld differential pressure meter designed for high-accuracy, field-deployable measurement of low-pressure differentials and derived air velocity in HVAC, cleanroom, and biosafety applications. It operates on the principle of piezoresistive pressure transduction, calibrated to deliver traceable, stable readings across its full ±2500 Pa range. Unlike general-purpose pressure gauges, the 6720-DP integrates dual-sensor architecture—capable of simultaneous static and differential pressure acquisition—and supports direct velocity calculation via integrated Pitot tube or multi-point wind matrix probes. Its design complies with fundamental metrological requirements outlined in ISO 5801 (fan testing), ISO 14644 (cleanroom classification), and NSF/ANSI 49 (biosafety cabinet certification), making it suitable for GLP-aligned validation protocols and routine QA/QC workflows.
Key Features
- Precision differential pressure measurement with ±1.5% of reading ±0.25 Pa accuracy and 0.001 Pa resolution—optimized for low-delta applications such as fume hood face velocity verification and filter leak testing.
- Integrated air velocity computation using industry-standard calibration coefficients (K-factor adjustment) for Pitot tubes (0.15–40 m/s) and wind matrices (0.15–15 m/s), supporting real-time derivation of volumetric flow when paired with duct geometry inputs.
- 4.3-inch full-color capacitive touchscreen interface with intuitive icon-driven navigation, multi-language support (English, Japanese, Chinese, Korean), and on-device data review including min/max/average/accumulated values.
- Bluetooth 4.2 wireless connectivity enabling secure pairing with iOS and Android mobile devices running the official KANOMAX SmartLog app—supporting remote parameter configuration, live data streaming, and time-stamped audit trails.
- Onboard storage for up to 8,000 measurement records with timestamp, sensor ID, and environmental metadata; synchronized backup to mobile app (10,000 records) with CSV export capability via USB or Bluetooth.
- Low-power architecture delivering up to 14 hours of continuous operation on four standard AA alkaline cells, with automatic sleep mode activation after 5 minutes of inactivity to preserve battery life.
Sample Compatibility & Compliance
The 6720-DP is validated for gaseous media only (air, nitrogen, dry compressed air) under non-condensing conditions. It is not rated for liquid or corrosive gas exposure. Its pressure port configuration adheres to ISO 5167-compliant tapping standards when used with Pitot-static tubes and conforms to EN 12599 requirements for HVAC system commissioning. The instrument’s measurement uncertainty budget has been verified per ISO/IEC 17025 principles in accredited calibration laboratories. While not FDA 21 CFR Part 11–certified out-of-the-box, its timestamped, user-identifiable data logs—including operator ID input via app—support GMP-compliant documentation when deployed within controlled procedural frameworks.
Software & Data Management
The KANOMAX SmartLog mobile application (iOS/Android) provides full instrument control, including K-factor tuning, unit conversion (Pa, mmH₂O, inH₂O, m/s, ft/min), statistical analysis (mean, SD, trend graphs), and customizable report generation. All measurements are tagged with GPS coordinates (optional), ambient temperature/humidity (when external sensors are connected), and device serial number. Data exports comply with ASTM E2911-13 standards for electronic record integrity. USB-C cable connection enables direct firmware updates and bulk data transfer to Windows-based analysis platforms without requiring cloud intermediaries.
Applications
- Biosafety cabinet and fume hood face velocity verification per NSF/ANSI 49 and EN 12464-1.
- Cleanroom differential pressure monitoring during ISO 14644-3 certification and routine surveillance.
- HVAC duct static pressure profiling, fan performance testing (per AMCA 210), and system balancing.
- Filter integrity testing via upstream/downstream pressure drop analysis in pharmaceutical and semiconductor facilities.
- Energy audit support through real-time airflow quantification in variable air volume (VAV) boxes and terminal units.
- Academic and industrial R&D labs requiring portable, NIST-traceable low-pressure metrology.
FAQ
Is the 6720-DP suitable for measuring negative pressure in isolation rooms?
Yes—the ±2500 Pa range fully covers typical negative pressure differentials required in airborne infection isolation rooms (AIIRs), per CDC and ASHRAE 170 guidelines.
Can the device store calibration certificates internally?
No—calibration records must be maintained externally; however, each measurement includes a unique timestamp and instrument ID to facilitate traceability when cross-referenced with lab calibration logs.
Does Bluetooth printing support label or thermal receipt formats?
Yes—paired Bluetooth thermal printers (e.g., Zebra ZQ510, Star SM-L200) output ANSI-formatted test reports with header fields for site name, technician ID, date/time, and pass/fail flags based on user-defined thresholds.
What is the recommended recalibration interval?
KANOMAX recommends annual recalibration against a certified reference standard in accordance with ISO/IEC 17025-accredited laboratories, especially when used in regulated environments.
Can multiple 6720-DP units be managed simultaneously via one mobile device?
No—the SmartLog app supports one active instrument connection at a time; however, historical datasets from multiple units can be merged and analyzed post-hoc in spreadsheet or LIMS environments.
