Overview
The KANOMAX 6720-DP Grid is a high-precision, multi-sensor environmental monitoring instrument engineered for comprehensive air velocity, volumetric flow, and differential pressure measurement in HVAC commissioning, cleanroom validation, duct traverse surveys, and industrial ventilation system audits. Unlike single-point anemometers, the 6720-DP Grid integrates a detachable 16-point grid sensor array with a calibrated pitot tube probe—enabling simultaneous spatial averaging of airflow across duct cross-sections per ISO 14644-3 and ASHRAE Guideline 12. Its dual-mode operation supports both point-wise pitot-based velocity calculation (via Bernoulli’s principle) and matrix-based area-averaged flow estimation, delivering traceable results compliant with EN 12599 and ASTM D1076 for air handling unit performance verification.
Key Features
- 4.3-inch full-color capacitive touchscreen interface with intuitive icon-driven navigation and real-time waveform visualization
- Integrated dual-sensor architecture: interchangeable pitot tube (0.15–40 m/s) and 4×4 grid probe (0.15–15 m/s) for flexible application deployment
- Simultaneous triple-parameter acquisition: air velocity, volumetric flow (40–4300 m³/h), and differential pressure (−2500 to +2500 Pa)
- Bluetooth 5.0 wireless communication enabling secure pairing with iOS/Android devices running the official KANOMAX FieldLink™ app
- On-device data storage for up to 8,000 measurement records; mobile app extends capacity to 10,000 entries with timestamp, location tagging, and custom annotation
- K-factor adjustment functionality for field calibration compensation against duct geometry, turbulence intensity, and probe alignment error
- Auto-power management: enters low-power standby after 5 minutes of inactivity; full operational runtime ≥14 hours on standard AA alkaline cells
- USB-C port supporting firmware updates, bulk data export (CSV/Excel), and direct connection to USB-powered thermal printers
Sample Compatibility & Compliance
The 6720-DP Grid is validated for use in non-corrosive, non-explosive ambient air streams within temperature (0–60 °C) and humidity (0–100 %RH, non-condensing) limits defined by IEC 60529 IP42 ingress protection. Its pitot tube and grid sensors meet dimensional tolerances specified in ISO 8502-2 for velocity probe calibration traceability. The instrument conforms to electromagnetic compatibility requirements per EN 61326-1:2013 and carries CE marking under the EU Measuring Instruments Directive (MID) Annex MI-004 for flow meters. All stored measurement data include audit-ready metadata (date/time, operator ID, sensor serial, environmental conditions), satisfying GLP and ISO/IEC 17025 documentation requirements for accredited laboratories.
Software & Data Management
KANOMAX FieldLink™ software provides full configuration control, live telemetry streaming, and post-processing analytics—including duct area integration, traverse point weighting, and ISO 14644-3 class compliance reporting. Data exports support CSV, PDF report generation (with customizable templates), and direct import into LIMS or building management systems via RESTful API. The embedded database enforces FDA 21 CFR Part 11-compliant electronic signatures, user-level access control, and immutable audit trails for all record modifications. Firmware updates are delivered via signed OTA packages verified through SHA-256 checksum integrity checks.
Applications
- HVAC system balancing and TAB (Testing, Adjusting, Balancing) per NEBB Procedural Standards
- Cleanroom airflow uniformity mapping and ISO Class verification in pharmaceutical manufacturing suites
- Exhaust hood face velocity validation under OSHA 1910.1450 and ANSI/AIHA Z9.5
- Duct leakage testing using differential pressure decay methodology (ASTM E779)
- Industrial fume extraction system performance audits in chemical processing facilities
- Energy efficiency assessments per ASHRAE Standard 111 and ISO 5167-4 for flow coefficient derivation
FAQ
Does the 6720-DP Grid require annual factory recalibration?
No mandatory annual recalibration is stipulated; however, KANOMAX recommends traceable verification against NIST-traceable reference standards every 12 months or after mechanical shock, per ISO/IEC 17025 Clause 6.5.
Can the grid sensor be used independently without the main unit?
No—the grid sensor operates exclusively as a slave module powered and interrogated via the host 6720-DP unit; no standalone functionality is implemented.
Is differential pressure measurement intrinsically zero-stable over time?
Yes—the internal piezoresistive transducer incorporates auto-zero compensation at power-on and during idle periods, maintaining baseline drift <±0.1 Pa/24 h at 25 °C.
What file formats are supported for data export?
Native CSV (UTF-8 encoded), PDF reports with embedded graphs and metadata, and XML schema-compliant exports for enterprise integration.
Are replacement grid sensors available with NIST-traceable calibration certificates?
Yes—each grid sensor is supplied with a manufacturer-issued calibration certificate referencing NIST SRM 2780, valid for 12 months from date of issue.
