Ashcroft 1188 Low Pressure Bellows Gauge

The Ashcroft® 1188 bellows pressure gauge is an ASME-style low-pressure gauge built around a bellows-actuated sensing mechanism for high resolution at very low pressures – from 5 in.H₂O upward – where standard Bourdon-tube gauges lack sensitivity. The bellows element and an easily adjustable micrometer pointer make the 1188 suited for furnace and combustion-system draft monitoring, low-pressure gas distribution, filtration differential measurement, and chemical-process vent monitoring.

Wetted parts are available in bronze, 316 stainless steel, and Monel® to match the process media, and the gauge can be supplied with integrated Ashcroft diaphragm seals for service on corrosive, viscous, or solids-bearing media. As an authorized Ashcroft distributor, BriceBarclay quotes and orders the 1188 direct from Ashcroft across the common low-pressure ranges and wetted-material options – request a configured quote and we will confirm specs and factory lead time for your application.
