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

Overview

The Kanomax 6720-DP Grid is a high-precision, multi-parameter environmental monitoring instrument engineered for comprehensive HVAC commissioning, ventilation system balancing, and indoor air quality (IAQ) validation. It integrates three core measurement modalities—air velocity (via dual-mode sensing), volumetric airflow, and differential pressure—within a single handheld platform. Its operational principle combines pitot-static pressure differential measurement (per ISO 10780 and ASHRAE Guideline 1) with grid-based thermal anemometry for spatially resolved face velocity profiling across grilles, diffusers, and duct cross-sections. Designed specifically for TAB (Testing, Adjusting, and Balancing) professionals and facility engineers, the 6720-DP Grid enables real-time, traceable quantification of supply/exhaust airflow distribution, filter resistance, hood face velocities, and room pressure differentials—critical parameters in cleanroom certification (ISO 14644-3), hospital HVAC compliance (ASHRAE 170), and laboratory ventilation safety (ANSI/AIHA Z9.5).

Key Features

• Dual-sensor architecture: Interchangeable pitot tube (0.15–40 m/s) and 16-point grid probe (0.15–15 m/s) for flexible application across ducts, registers, and laminar flow hoods.
• Simultaneous triple-parameter acquisition: Synchronized measurement and display of velocity, volumetric flow (40–4300 m³/h), and differential pressure (−2500 to +2500 Pa) on a 4.3-inch capacitive touchscreen.
• Traceable calibration architecture: Factory-calibrated sensors with documented uncertainty budgets; supports user K-factor adjustment per ISO 5167 for system-specific correction of pitot coefficient deviations.
• Extended data integrity: Internal non-volatile memory stores 8,000 measurement sets with timestamp, location tag, and sensor configuration metadata; mobile app extends capacity to 10,000 records with CSV export and audit-ready formatting.
• Low-power embedded design: Optimized firmware with auto-sleep mode after 5 minutes of inactivity; 14-hour runtime on standard AA batteries meets full-shift field requirements without AC dependency.
• Bluetooth 5.0 Class 1 connectivity: Secure pairing with iOS/Android devices for live telemetry, remote configuration, and direct printing via certified Bluetooth thermal printers (e.g., Zebra ZQ520).

Sample Compatibility & Compliance

The 6720-DP Grid is validated for use across commercial, healthcare, and pharmaceutical environments where regulatory-grade airflow verification is mandated. Its measurement methodology conforms to ASTM D5465 (standard test method for airflow in ducts using pitot tubes), ISO 14644-3 Annex B (cleanroom airflow uniformity testing), and EN 12599 (ventilation system commissioning procedures). The device operates reliably under non-condensing conditions from 0–60 °C and 0–100 %RH—covering typical HVAC operating envelopes. All stored datasets include embedded timestamps, battery voltage logs, and sensor ID tags to support GLP/GMP documentation requirements. Optional accessories—including telescopic poles (up to 3.2 m), NIST-traceable calibration certificates, and AC adapters—enable deployment in ceiling-mounted diffuser arrays and high-bay industrial settings.

Software & Data Management

Kanomax provides a dedicated cross-platform application (Windows/macOS/iOS/Android) that functions as both a real-time control interface and post-processing workstation. The software implements role-based access controls, enabling supervisor-level review of technician-collected data prior to report generation. Export formats include CSV (with ISO 8601 timestamps), PDF summary reports (customizable templates), and XML for integration into CMMS or LIMS platforms. Audit trail functionality complies with FDA 21 CFR Part 11 requirements when used with electronic signatures and password-protected user accounts. USB-C data transfer ensures compatibility with modern lab infrastructure, while Bluetooth pairing eliminates cable clutter during dynamic balancing workflows.

Applications

• HVAC system balancing: Quantitative verification of design airflow at terminal devices per ASHRAE Fundamentals Chapter 46.
• Cleanroom classification: Face velocity mapping across HEPA/ULPA filter banks in ISO Class 5–8 environments.
• Fume hood performance testing: Static pressure drop and face velocity uniformity assessment per ANSI/AIHA Z9.5 Section 6.2.
• Pharmaceutical isolator qualification: Differential pressure monitoring between adjacent classified zones (e.g., Grade A/B corridors).
• Energy audit support: Baseline airflow characterization for retrocommissioning and demand-controlled ventilation optimization.
• Academic and industrial research: Boundary layer profiling in wind tunnel test sections and ventilation mock-ups.

FAQ

What standards does the 6720-DP Grid comply with for HVAC commissioning?
It aligns with ASHRAE Guideline 1, ISO 12599, and ASTM D5465 for pitot-based airflow measurement, and supports cleanroom testing per ISO 14644-3 Annex B.
Can the grid probe and pitot tube be calibrated independently?
Yes—each sensor type carries its own calibration certificate with unique serial-numbered traceability to JCSS (Japan Calibration Service System) standards.
Is differential pressure measurement suitable for filter monitoring?
Absolutely—the ±0.25 Pa base accuracy and 0.001 Pa resolution enable early detection of particulate loading on HEPA filters and VAV box actuators.
Does the device support automated report generation for TAB documentation?
Yes—the companion software includes pre-formatted ASHRAE-compliant report templates with automatic calculation of balance ratios, tolerance bands, and deviation flags.
How is data security maintained during Bluetooth transmission?
All BLE communications use AES-128 encryption; no raw sensor data is stored on mobile devices unless explicitly exported by authorized users.
