Kanomax 6720-DP Grid Multi-Parameter Air Velocity & Flow Analyzer

Overview

The Kanomax 6720-DP Grid is a high-precision, multi-parameter air velocity and volumetric flow analyzer engineered for HVAC commissioning, routine maintenance, and performance validation in commercial, pharmaceutical, and cleanroom environments. It operates on the fundamental principles of pitot-static differential pressure measurement—applying Bernoulli’s equation to derive dynamic pressure from total and static pressure differentials—and integrates a calibrated 16-point grid sensor array for spatially resolved face velocity profiling across ducts, grilles, and hoods. Unlike single-point anemometers, the 6720-DP Grid enables simultaneous acquisition of average face velocity, volumetric flow rate (calculated using cross-sectional area and mean velocity), and real-time differential pressure—critical parameters for ASHRAE 110, ISO 14644-3, and EU GMP Annex 1 airflow qualification. Its dual-sensor architecture supports both high-velocity applications (e.g., supply ducts) and low-velocity laminar fields (e.g., biosafety cabinet inflow), ensuring traceable, repeatable measurements under varying system loads.

Key Features

• Integrated 4.3-inch full-color capacitive touchscreen interface with intuitive icon-driven navigation—designed for glove-compatible operation in technical environments.
• Simultaneous real-time measurement of air velocity (0.15–40 m/s via pitot tube; 0.15–15 m/s via grid array), volumetric flow (40–4300 m³/h), and differential pressure (−2500 to +2500 Pa).
• Bluetooth 5.0 wireless connectivity enabling secure pairing with iOS/Android mobile devices for remote control, live data streaming, and synchronized timestamped logging.
• Dual-storage architecture: onboard memory retains up to 8,000 measurement records with full metadata (date/time, sensor ID, K-factor, environmental conditions); companion mobile application stores up to 10,000 records with export-ready CSV/PDF generation.
• Configurable K-factor adjustment for compensating nozzle geometry, duct roughness, and installation effects—essential for compliance with ISO 10780 and ASTM D2513 calibration protocols.
• Low-power architecture with auto-sleep mode after 5 minutes of inactivity; powered by four standard AA alkaline cells delivering ≈14 hours of continuous operation under typical field use.

Sample Compatibility & Compliance

The 6720-DP Grid is validated for use with standardized HVAC components including supply/exhaust grilles, VAV boxes, HEPA filter banks, fume hoods, and laminar flow workstations. Its grid sensor array conforms to ISO 14644-3 Annex B requirements for multi-point velocity mapping, while its differential pressure channel meets EN 12599 test method tolerances for fan system characterization. All measurement algorithms are traceable to NIST-certified reference standards via Kanomax’s internal calibration hierarchy. The instrument supports audit-ready documentation workflows compliant with FDA 21 CFR Part 11 (when used with validated software configurations), ISO/IEC 17025 laboratory accreditation criteria, and EU GMP Annex 1 Annex A airflow verification protocols.

Software & Data Management

The bundled Kanomax AirFlow Manager software (Windows/macOS) and mobile application provide full configuration, real-time visualization, and post-processing capabilities—including automatic flow calculation using user-defined duct dimensions, statistical summary (mean, SD, min/max), and pass/fail threshold overlays per ISO 14644-1 Class limits. Data exports include time-stamped CSV files with embedded calibration certificates and instrument serial numbers. Bluetooth-enabled thermal printers generate field-ready reports with QR-coded traceability links. All stored records include immutable timestamps, battery voltage logs, and sensor status flags—supporting GLP/GMP-compliant record retention and electronic signature workflows.

Applications

• HVAC system balancing and TAB (Testing, Adjusting, and Balancing) per ASHRAE Guideline 129 and NEBB Procedural Standards.
• Face velocity verification of chemical fume hoods (ANSI/AIHA Z9.5), biosafety cabinets (NSF/ANSI 49), and laminar flow hoods.
• Filter bank integrity assessment through uniformity index calculation across grid points.
• Duct leakage testing via differential pressure monitoring during pressurization tests (ASTM E779).
• Room air change rate validation in cleanrooms and controlled environments (ISO 14644-1, EU GMP Annex 1).
• Energy audit support through volumetric flow trending and fan power consumption correlation.

FAQ

What is the K-factor, and why is it required for accurate flow measurement?
The K-factor is a dimensionless correction coefficient that accounts for geometric and fluid-dynamic deviations between ideal and actual flow profiles. It must be applied when measuring in non-ideal duct sections (e.g., upstream of bends or dampers) and is essential for achieving traceable accuracy per ISO 10780.
Can the 6720-DP Grid be used in high-humidity environments without condensation risk?
Yes—the instrument is rated for operation at 0–100 %RH provided ambient conditions remain non-condensing (i.e., dew point remains below housing temperature). For prolonged exposure above 85 %RH, use of the optional desiccant-equipped carrying case is recommended.
Is firmware update capability supported over Bluetooth?
Firmware updates require USB connection to a host PC running Kanomax AirFlow Manager; Bluetooth is reserved for data transmission and remote control functions only.
How does the grid sensor array differ from a standard pitot tube in terms of measurement uncertainty?
The grid array reduces spatial sampling error by capturing 16 discrete velocity vectors simultaneously, yielding a statistically robust mean face velocity with lower standard deviation than sequential single-point scans—particularly critical for validating uniformity per ISO 14644-3 Annex B.
Does the device meet electromagnetic compatibility (EMC) requirements for hospital and laboratory use?
Yes—the 6720-DP Grid complies with IEC 61326-1:2013 Class B emission and immunity specifications, ensuring reliable operation near MRI suites, analytical balances, and other sensitive instrumentation.
