KANOMAX Model 6720-DP Handheld Differential Pressure Meter with Remote Monitoring and Bluetooth Data Transmission

Overview

The KANOMAX Model 6720-DP is a precision-engineered handheld differential pressure meter designed for high-accuracy, field-deployable measurement of low-differential pressures and air velocity in HVAC, cleanroom, biosafety cabinet, and industrial ventilation applications. It operates on the principle of piezoresistive pressure transduction, delivering stable, repeatable readings across its full range of −2500 to +2500 Pa. Unlike conventional analog gauges or basic digital meters, the 6720-DP integrates dual-sensor architecture—capable of simultaneous differential pressure and velocity acquisition—when paired with optional probes including Pitot tubes and KANOMAX’s proprietary Air Velocity Matrix. Its core function extends beyond point measurement: it serves as an intelligent node in modern facility QA/QC workflows, enabling real-time remote monitoring, synchronized data logging, and traceable reporting via secure Bluetooth 5.0 connectivity.

Key Features

• 4.3-inch full-color capacitive touchscreen interface with intuitive icon-based navigation and multi-language support (English, Chinese, Japanese, Korean)
• Dual-mode operation: standalone differential pressure measurement (±2500 Pa) or air velocity profiling (0.15–40 m/s with Pitot tube; 0.15–15 m/s with Air Velocity Matrix)
• High-resolution pressure sensing: 0.001 Pa resolution with accuracy of ±1.5% of reading ±0.25 Pa (per ISO 5801 and ASHRAE 110 verification protocols)
• Velocity measurement compliance: meets ASTM D1076 and ISO 14644-3 requirements for cleanroom airflow uniformity testing
• Low-power architecture: 4 × AA alkaline batteries provide up to 14 hours of continuous operation; automatic sleep mode activates after 5 minutes of inactivity
• Onboard clock with time-stamped data logging, battery-level indicator, and user-configurable K-factor calibration for probe-specific compensation
• Integrated Bluetooth 5.0 module supporting secure pairing with iOS and Android devices running the official KANOMAX SmartLink app

Sample Compatibility & Compliance

The 6720-DP is validated for gaseous media only (air, nitrogen, dry compressed air) and is not rated for liquids or corrosive/condensing environments. Its pressure sensor is sealed and temperature-compensated over 0–60 °C (non-condensing), ensuring minimal thermal drift during extended field use. The instrument conforms to IEC 61000-4 electromagnetic compatibility standards and carries CE marking for use within the European Economic Area. For regulated environments—including GLP laboratories, pharmaceutical cleanrooms (ISO 14644-1 Class 5–8), and biosafety level 2+ facilities—the device supports audit-ready data integrity through timestamped storage, user-defined test IDs, and exportable CSV/Excel reports. While not FDA 21 CFR Part 11–certified out-of-the-box, its app-based workflow enables implementation of supplementary procedural controls (e.g., operator login, electronic signature protocols) required under GMP Annex 11.

Software & Data Management

The KANOMAX SmartLink mobile application (iOS/Android) provides full remote control of the 6720-DP, including real-time parameter configuration, live waveform visualization, and post-test statistical analysis (min/max/avg/cumulative values). All measurements are automatically tagged with GPS coordinates (optional), ambient temperature, and operator ID. Data synchronization is bidirectional: 8,000 records are retained locally on-device; up to 10,000 records may be stored and organized within the app. Export options include USB mass-storage mode (via included cable) and direct Bluetooth printing to compatible thermal printers. Raw datasets support batch export in ISO-compliant CSV format, facilitating integration with LIMS platforms and automated QA dashboards.

Applications

• Biosafety cabinet face velocity mapping per NSF/ANSI 49 and EN 12469
• HEPA filter leak testing and duct static pressure balancing in ISO-classified cleanrooms
• HVAC system commissioning, including fan performance curves, damper authority verification, and outdoor air intake quantification
• Room pressurization validation for hospital isolation rooms and pharmaceutical manufacturing suites
• Energy audit support—measuring pressure differentials across coils, filters, and dampers to identify airflow resistance anomalies
• Academic and industrial R&D requiring portable, high-fidelity differential pressure capture under variable environmental conditions

FAQ

Does the 6720-DP require annual recalibration?
Yes. KANOMAX recommends traceable recalibration every 12 months against NIST-traceable standards, particularly when used in regulated environments. Field zeroing is supported via built-in auto-zero function.
Can the device measure negative gauge pressure?
No—it measures differential pressure only (ΔP between two ports), not absolute or vacuum pressure. Negative values indicate reverse flow direction relative to probe orientation.
Is the Bluetooth connection encrypted?
Bluetooth pairing uses standard BLE security (AES-CCM encryption at link layer); data payloads are transmitted unencrypted but are intended for local, short-range use per ISO/IEC 27001 site policies.
What is the maximum distance for reliable Bluetooth communication?
Up to 10 meters line-of-sight under typical indoor conditions; signal attenuation increases significantly with metallic obstructions or RF interference from HVAC motors.
Are firmware updates available?
Yes—updates are distributed via the SmartLink app and include enhancements to measurement algorithms, UI responsiveness, and compliance reporting templates.
