Overview

The CRS456 consists of a water-level and water-temperature sensor that has its own time clock and memory to store the collected data, in a compact titanium case. This frees users to place the sensor in remote sites and let it collect data for long periods. The sensor can then be retrieved, connected to a PC via a micro-USB port, and the data transferred to the PC. HydroSci software is included and elegantly supports test setup, data retrieval, and data display. Long battery life and rugged construction mean you can trust the CRS456 to collect important data. Low cost and ease of use make it a good choice in a variety of applications. The CRS451 is the same as this, but with a stainless-steel case.

Technical Description

The CRS456 has several pressure range options. The CRS456 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 CRS456. Users can configure the CRS456 to monitor surface water, ground water, or a standard pump test.

HydroSci software will also compensate the measurements for barometric pressure using an additional CS456 or a CS451 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.
