testo 420 - Differential pressure manometer

 

Differential Pressure Measuring Instrument with Practical Functions

You can use a pitot tube and compatible connection hoses (both optional) to measure the flow velocity and volume flow in ventilation ducts. Timed and multi-point mean calculation, as well as the combination of the two, together with simple input of the duct geometry, provide you with accurate flow measurements in ducts.

Automatic zeroing ensures higher accuracy for low pressures. All measuring values are easy to read on the large backlit display.

 

Documenting the Measurement Data

Measurement data can be stored in the testo 420 for analysis and documentation. It's easy to manage the measurement data on a PC without any additional software, via the testo 420's plug and play capability.
