Testo 0560 0420

The differential pressure gauge testo 420 is suitable for precise differential pressure measurement up to 120 Pa, for example, when checking filters in HVAC systems. The testo 420 calculates flow velocity and volumetric flow rate. Additionally, the device allows for absolute pressure measurement.

Differential pressure gauge with practical device functions. With the help of a pitot tube and appropriate connection hoses (both optional), you can measure flow velocity and volumetric flow rate in the ventilation duct. Temporal and point averaging, as well as the combination of temporal and point averaging with simple input of the duct geometry, assist you in measuring within the duct. At low pressures, the automatic zero adjustment ensures higher accuracy. All measured values are easy to read on the large, illuminated display.

Documentation of measurement data. For analysis and documentation purposes, measurement data can be stored in the differential pressure gauge. Managing the measurement data on a PC is straightforward and requires no additional software thanks to the plug-and-play function.
