Description
Overview
The Dwyer 2230 is an analog dial differential pressure gauge featuring precision engineering for accurate pressure measurement in a robust package. The gauge employs a precision helix mechanism with jeweled, shock-resistant bearings and a calibrated range spring for consistent, long-life operation. A silicone rubber diaphragm provides reliable pressure sensing, while the die-cast aluminum case with baked gray finish offers excellent corrosion resistance, having passed 168-hour salt spray testing.
