Product Details | DIAL INDICATING PRESSURE GAGE

6685-00-546-9323 An instrument designed to measure air, gas, fluid, and vapor pressure by means of an internal pressure sensitive element (bellows, bourdon tube, transducer/transmitter and the like) which transmits energy, by direct linkage, to the indicating pointer of a scale or a digital display, calibrated in units of pressure. It may include a temperature equivalent scale. For items that do not have an internal pressure sensitive element see INDICATOR, PRESSURE.205138600004220000042400027Safety and Rescue Equipment66200018Engine Instruments66850073Pressure, Temperature, and Humidity Measuring and Controlling Instruments
