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
