Testo 420 Air Flow Hood Kit Includes Hood - 0563 4200

The Testo 420 volume flow hood is suited for HVAC systems and has a control panel for displaying measurement data. The control panel can be tilted or removed to suit user requirements.

The Testo 420 measuring instrument lets you measure flow velocity, volume flow, absolute pressure, temperature, and relative humidity. The automatic zeroing function ensures higher accuracy for low pressures.

All measuring values are easy to read on the large display with an illumination function. For analysis and documentation, measurement data can be saved, and measurement protocols can be created directly on-site using the testo 420 App. In addition, the measurement data can be easily accessed via PC without any additional software thanks to the plug & play function.

The Testo 420 volume flow hood, with its integrated measuring instrument, was not only developed to measure volume flow measurement. The measuring instrument can also be taken off the hood to measure a duct's pressure, flow, and volume flow measurements. Attach a Pitot tube and connection hoses (both optional) with integrated, timed, and multi-point mean calculations.

Key Features

• Sixteen measurement points that record Temperature, Humidity, Differential & Absolute Pressure.
• Highly precise readings at swirl outlets thanks to flow straightener.
• IOS & Andriod App Integration via Bluetooth connectivity.
• Onsite report generation & email.

HIGH MEASURING ACCURACY AT SWIRL OUTLETS THANKS TO VOLUME FLOW STRAIGHTENER

Volume air flow is frequently measured at swirl outlets. Air flows are often incorrectly measured due to the turbulent air at these outlets.

The Testo 420 enables you to reduce these measurement errors significantly. The integrated volume flow straightener calms the turbulence and converts it into a virtually uniform air flow. This enables accurate calculation of volume flow in the 80 to 3,500 m3/h range.

CREATE PROTOCOLS DIRECTLY ON-SITE AND E-MAIL THEM USING THE TESTO 420 APP

Please take advantage of other practical functions and download our free App because the App connection enables mobile devices such as smartphones and tablets to be used as a secondary display and as a remote control via Bluetooth. 

The App enables live measurement on HVAC systems using a start and stops function and saving measurement data in text format. You can create the measurement protocol directly on-site using the App. Measurement results, such as the overall volume flow and the air exchange rate, can be directly assigned to customer-specific protocol templates. You can then send your readings and protocols via the e-mail function. This means you save a considerable amount of time and increase efficiency.
