Ashcroft 4-1/2 inch low-pressure bellows gauge, model 1188, part number 45-1188-AS-02B-30IW, is designed for very-low-pressure measurement with a 0 to 30 inches of water (IW) range and a back 1/4 NPT male process connection (02B). The gauge features a 4.5" dial in a phenolic case with an all-stainless steel movement. Commonly used in oil and gas, wastewater, and process industries for monitoring low-pressure and vacuum conditions, this configuration provides back-mounted connection for easy integration into existing instrumentation.
