The DM housing is specifically designed to mount in the same diameter cutout as a standard Magnehelic gage. A wide range of models are available factory calibrated to specific ranges. The polycarbonate molded housing features integral pressure connections, which reduces installation time. Digital push-button zero and span simplify calibration over typical turn-potentiometers.
