Model 6650 Digital Manometer measures and monitors positive, negative, and differential air pressure from 0-10” wc. Custom ranges are available. In contrast with hydrostatic manometers, which are typi¬cally bulky, fragile, and difficult to read and calibrate, the Model 6650 Digital Manometer is compact, sturdy, and easy to calibrate. The LCD pressure display is accurate and easy-to-read. The Digital Manometer includes all the functions necessary for measuring low pressure or balancing air systems. Using the Model 6650 Digital Manometer, pressure switches can be calibrated in the field. Pressure readings are displayed in four units of measure, and can be retained for service documentation.
