digitallaboratoryfor HVAC

· 12 pressure units · Wind speed measurement · Zero calibration and point calibration · Data retention (HOLD) · Mode of difference supported · Query the maximum and minimum values · Display with backlight · Automatic shut down · Low battery display 【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. 【APPLICATION】 · HVAC system · Pressure and wind speed of fan and blower · Filter · Laboratory · Negative pressure cabin, room · Pipeline gas pressure
