Model 4573 Series

The 4573 Series are battery powered downhole water level and temperature dataloggers well suited for recording water levels and temperatures in shallow wells, streams, lakes and freshwater wetlands. For saltwater deployments, such as brackish wetlands and tidal areas, the Model 4573-2 should be used. The 4573-1 (s/s) and 4573-2 (Titanium) are available in 4 pressure ranges with measurement accuracies between ±0.075% F.S. and ±0.05% F.S. For less demanding applications and/or where cost is a consideration, the Model 4573-3 with a polypropylene housing is available in 3 pressure ranges, with measurement accuracy ±0.1% F.S.
