Product Details
Made in China MC Air Pressure Gauge HVAC Gas Tester Differential Pressure Meter
Digital Manometer
Introductions:
YW-721 is an instrument for measuring pressure difference.
YW-721 is often used to measure small pressure difference (such as
detecting the permeability of a filter), air flow pressure, small
suction force, and pitot tube gas flow rate measurement.
YW-721 adopts high-quality pressure sensor with superior
performance. It has the advantages of fast, sensitive, good
stability and so on.
YW-721 supports zero calibration and point calibration, which can
effectively reduce the impact of zero drift
