Do you think you have a manometer that needs calibration? Easily check to see if two devices agree using this simple calibration test kit. Simply connect a known good device, and a device in question, to the Y tubing, and apply pressure using the bulb. Both devices should give the same reading. If they don't you definitely need recalibration.
