I-S gauges are very high quality gauges with very precise tolerances. These high pressure gauges will read consistently from 0-1500 PSI time and time again. They are constructed of a very clean looking stainless steel housing, and have a brass stem. I-S gauges come with the appropriate adapter to an 1/8 NPT thread and the prices include the fitting you choose to add the gauge inline very easily! They have an easy to read white face with black marked increments and our Induction Solutions logo in the center!
