1133 Differential Pressure Gauge

Brand: Ashcroft Inc
Does not ship to United States

The Type 1133 differential pressure gauge is an economical means for measuring very low pressure with high static between two independent pressure sources.

It uses a convoluted diaphragm to sense low inches of water differentials while ensuring no migration of the process media.
