Vibrating Wire Barometer | Model 4580-1

  • Model 4580-1 Barometer.
SKU:
Model 4580-1

The Model 4580-1 Vibrating Wire Barometer* provides a convenient means of correcting for barometric pressure changes on nearby unvented vibrating wire piezometers, which respond not only to water pressure changes but also to changes in atmospheric pressure. Vibrating Wire Barometers are calibrated at GEOKON and referenced to an absolute barometric reading in millibars. Installation is typically carried out in a vented enclosure with the sensor in a vertical position.
