Dwyer 0-2kpa All Stainless Steel Pressure Gauge Digital Magnehelic Gauge

Introduction

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.

Specification

Working principle

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 electronic factory, hVAC, purification table, spraying room, environmental protection dust removal equipment, air conditioning cabinet filter net pressure difference detection, etc.
