Series Information

The Ashcroft® 1127 differential pressure gauge is used to measure the differential pressure between two separate pressure sources. The standard stainless steel Bourdon system offers an advantage over similar bronze systems, generally not needing to be isolated from the process media using diaphragm seals and capillary lines. A good selection for system monitoring.
