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