Digiquartz® Pressure Instrumentation


Digiquartz® Broadband Barometers are used for meteorological applications where high resolution, accuracy, reliability, long-term stability and low total cost of ownership are critical parameters. Accuracy of ±0.08 hPa is achieved under both laboratory and field conditions. The Broadband Barometers measure absolute full-scale atmospheric pressure for measurements used in weather prediction, GPS-MET, climate studies, calibration standards, and as Digital Altimeter Setting Indicators at airports. High-resolution dynamic measurements of infrasound signals can be made with a sensitivity of 0.0003 Pa to detect microbaroms, severe weather, tornadoes, tsunamis, volcanic eruptions, avalanches, nuclear tests, wind-shear and wake-turbulence.
