Product Description

The testo 420 differential pressure measuring instrument is suitable for accurate differential pressure measurement up to 120 Pa, e.g. when checking filters in HVAC systems. Flow velocity and volume flow are calculated by the testo 420. The measuring instrument can also be used for absolute pressure measurement.

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, along with simple input of the duct geometry provide you with support for measurements in ducts.

The automatic zeroing ensures higher accuracy for low pressures. All measuring values are easy to read on the large display which has an illumination function.

Documenting the measurement data

Measurement data can be stored in the differential pressure measuring instrument for analyses and documentation. It's easy to manage the measurement data on the PC without any additional software, via the plug & play function.

Delivery Scope
