CSR451

Detailed Description

The CRS451 has several pressure range options. The CRS451 is unvented; therefore it is monitoring sealed gage pressure. For maximum accuracy, the data should be corrected for barometric pressure.

HydroSci software is available for download. This software simplifies the process of configuring the CRS451. Users can configure the CRS451 to monitor surface water, ground water, or a standard pump test.

HydroSci software will also compensate the measurements for barometric pressure using an additional CS451 or a CS456 as a reference sensor, or using a barometric pressure sensor from a nearby weather station.

HydroSci software will display the data in tabular or graphical formats.
