2000 0-0.25 WC Dwyer 2000-00 Magnehelic Differential Pressure Gauge
Dwyer pointer differential pressure gauges can achieve 2% accuracy
and up to 81 range options to meet the needs of a variety of
applications. The tried-and-true magnetic linkage principle, using non-wear
moving parts, can quickly indicate low pressure - positive
pressure, negative pressure (vacuum) or differential pressure of
air or non-corrosive gases. Its design is shockproof, shockproof and has the ability to
withstand overpressure. It does not evaporate, freeze liquid differential pressure meter
phenomenon, also does not cause poisoning or leveling problems.

It utilizes the frictionless Magnehelic motion principle,
eliminating wear, lag and clearance. No liquid filling, no vaporization and freezing, quick indication
of low pressure, non-corrosive gas pressure (positive, negative
(vacuum) and differential pressure). There are 81 ranges, with a minimum range of 0-60Pa(or 0-6mm water
column or 0-0.25 inch water column).
Application: used for measuring positive and negative pressure
difference; It is suitable for measuring positive and negative pressure
difference of clean workshop in pharmaceutical factory and
