Testo 420 Flow Hood – Airflow Meter HVAC for Air Velocity, Volume Flow, Temperature & Relative Humidity – CFM Meter for Airflow HVAC with Tiltable Display, Bluetooth, and App Compatibility - With NIST

Features

• Lightweight & Ergonomic; Weighing less than 6.4 lbs, the air flow meter offers comfortable handling with an ergonomic design and tiltable display, perfect for prolonged use in large spaces or above head height
• Precision Measurements; The testo 420 flow hood features a unique volume flow straightener to ensure accurate measurements even at turbulent swirl outlets. It is ideal for precise HVAC system testing and balancing
• Advanced Connectivity; Equipped with Bluetooth, the HVAC Airflow Meter CFM connects to your smartphone or tablet, allowing for remote monitoring, control, and report generation through the Testo 420 app
• Versatile Use; The detachable control unit doubles as a standalone device for pressure, flow, & volume measurements in ducts by adding optional pitot tubes and hoses. The CFM meter for airflow HVAC provides comprehensive data collection capabilities
• Convenient Reporting; Create and email measurement reports directly from the job site via the Testo Smart App, enhancing workflow efficiency and saving valuable time during HVAC inspections and maintenance
• Standardized; Take advantage of three calibrated temperature points with the included NIST standards testing certificate. The calibration ensures all regulatory requirements for the air flow meter are met

Description

The testo 420 Airflow Capture Hood - Rapid measurements of airflow in large rooms and swirl outlets Volume flow is frequently measured at swirl outlets, and airflow measurements are often incorrectly measured due to the turbulent air from these outlets. The testo 420 volume flow capture hood with its removable control unit offers a convenient solution for measurements of flow velocity, volume flow, absolute pressure, temperature and relative humidity in large rooms and swirl outlets. Automatic zeroing ensures a higher accuracy for low pressure.
