Yw-721 Dual Differential Input Manometer

Product Description

YW-721 Dual Differential Input Manometer Product Description
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.

FEATURES: 12 pressure units Wind speed measurement Zero calibration and point calibration Data retention (HOLD) Difference mode supported Query the maximum and minimum values Display with backlight Automatic shut down Low power reminder

APPLICATIONS: HVAC system Pressure and wind speed of fan and blower Filter Laboratory Negative pressure cabin, room Pipeline gas pressure
