This document provides an overview of pressure gauges, thermometers, switches, and diaphragm seals offered by Ashcroft. It describes their key features such as measurement ranges, materials, connections, accuracy levels, and certifications. A variety of models are detailed that can measure pressure, differential pressure, temperature and switch applications. They include bourdon tube, diaphragm, and capsule gauges as well as bimetal thermometers and molecular sieve systems. Pressure switches come in models for hazardous and general purpose use. Diaphragm seals isolate media and come in flanged, screwed, and in-line designs with multiple material options.
