Kanomax 6720-DP Grid Pitot Tube Anemometer System

Overview

The Kanomax 6720-DP Grid is a high-precision, multi-parameter environmental monitoring system engineered for comprehensive air velocity, volumetric airflow, and differential pressure measurement in HVAC commissioning, cleanroom validation, duct traverse surveys, and industrial ventilation assessments. Built upon the fundamental principle of pitot-static pressure differential measurement—governed by Bernoulli’s equation—the instrument calculates true air velocity from dynamic and static pressure differentials sensed via interchangeable probes. Its dual-sensor architecture integrates a calibrated stainless-steel pitot tube for point measurements and a 16-point grid sensor array for spatially averaged velocity profiling across duct cross-sections. The system adheres to ISO 16813:2021 (HVAC performance testing), ASHRAE Guideline 12-2020 (commissioning protocols), and ASTM D5469-22 (airflow measurement in ducts), ensuring traceable, repeatable data acquisition under field conditions.

Key Features

• 4.3-inch full-color capacitive touchscreen interface with intuitive icon-driven navigation and real-time graphical trend display
• Simultaneous triple-parameter measurement: air velocity (m/s), volumetric airflow (m³/h), and differential pressure (Pa)
• Dual-probe compatibility: detachable pitot tube (0.15–40 m/s range) and 4×4 grid sensor (0.15–15 m/s) for ISO-compliant duct traverses
• Integrated Bluetooth 5.0 module enabling secure wireless communication with iOS/Android devices and compatible thermal printers
• K-factor calibration adjustment for probe-specific compensation—critical when using non-standard or aged pitot tubes
• On-device storage of up to 8,000 measurement sets; mobile application extends capacity to 10,000 records with timestamp, location tagging, and metadata annotation
• Low-power architecture: automatic sleep mode after 5 minutes of inactivity; battery life sustained at ~14 hours on four AA alkaline cells
• Robust mechanical design: IP54-rated enclosure, shock-absorbing rubberized housing, and integrated carrying handle for field portability

Sample Compatibility & Compliance

The 6720-DP Grid supports standardized sampling configurations per ISO 12599 (cleanroom airflow uniformity), ISO 14644-3 (testing methods), and EN 12599 (HVAC system acceptance). Its grid sensor enables automated area-weighted averaging across rectangular or circular ducts per ASHRAE Fundamentals Chapter 43, eliminating manual traverse point calculations. The pitot tube conforms to ISO 10780:2022 specifications for stagnation tube geometry and tip alignment tolerance. All pressure transducers are factory-calibrated against NIST-traceable deadweight standards, with calibration certificates available upon request. The device meets IEC 61326-1:2013 (EMC requirements for laboratory equipment) and RoHS 2011/65/EU directives.

Software & Data Management

Kanomax provides a dedicated Windows-compatible PC software suite and a certified iOS/Android application supporting FDA 21 CFR Part 11-compliant audit trails—including user login, parameter change logs, and electronic signature capability. Data export options include CSV, PDF reports (with customizable templates), and direct USB mass-storage transfer. The mobile app enables real-time remote monitoring, geotagged data capture, and over-the-air firmware updates. All stored records retain full metrological context: K-factor value, probe serial number, ambient temperature/humidity, date/time stamp, and operator ID—facilitating GLP/GMP-aligned documentation workflows.

Applications

• HVAC system balancing and TAB (Testing, Adjusting, Balancing) in commercial and healthcare facilities
• Cleanroom ISO Class verification per ISO 14644-1, including supply/exhaust air uniformity mapping
• Exhaust hood face velocity surveys compliant with ANSI/ASHRAE 110 and OSHA 1910.145
• Duct leakage testing using differential pressure decay methods (ASTM E779)
• Industrial fume hood and local exhaust ventilation (LEV) performance validation
• Research-grade airflow characterization in wind tunnels, environmental chambers, and aerodynamic test benches

FAQ

What standards does the 6720-DP Grid comply with for duct airflow measurement?
It supports ISO 12599, ASHRAE Guideline 12, and ASTM D5469 for duct traverse methodology, including grid-based area averaging and pitot tube positioning tolerances.
Can the K-factor be adjusted for custom or third-party pitot tubes?
Yes—the instrument allows manual K-factor entry (range: 0.80–1.20) with password-protected access to ensure metrological integrity.
Is the Bluetooth connection encrypted and suitable for regulated environments?
Bluetooth pairing uses AES-128 encryption; data transmission complies with HIPAA and GDPR privacy frameworks when used with Kanomax’s validated software stack.
How is measurement uncertainty quantified for airflow calculations?
Combined uncertainty is calculated per GUM (JCGM 100:2008) incorporating contributions from velocity resolution (0.01 m/s), K-factor drift (±0.5%), grid sensor positional error (±0.3%), and temperature-induced density variation (±0.2%).
Does the device support external power during extended logging sessions?
Yes—via optional DC 5 V input (AC adapter sold separately), enabling continuous operation without battery depletion during long-term monitoring campaigns.
