Specifications

DESCRIPTION:

YW-721 is an instrument for pressure difference measurement. YW-721 is often used to measure the small pressure difference (such as detecting the permeability of the filter), air flow pressure, small suction force, and pitot tube gas flow rate measurement.


YW-721 is used high-quality pressure sensor with superior performance. It is with advantages of fast, sensitive, and good stability.

YW-721 supports zero calibration and point calibration, which can effectively reduce the impact of zero drift.

 

FEATURES:
12 pressure units
