Water Level Dataloggers

Water Level Dataloggers Combined Logger and Pressure Transducer Monitors Groundwater, Stormwater, Surface Water and Sewers

Made for remote monitoring, these Water Level Dataloggers record water level or pressure data. Each can record more than 81,000 readings. Four recording options include fast (10 samples/second), programmable interval (one second to multiple years), logarithmic and exception. Loggers deliver readings for temperature range from –40°to 185°F, humidity range from 0–95% noncondensing and barometric pressure accuracy of 0.1% full scale at constant temperature (0.2% above 70°F). Two 9V lithium batteries power each unit for about one year and a third battery preserves your data if the two main batteries fail. Nonvolatile Flash memory. USB port allows connection to your computer or laptop.
Each 1-7/8"-dia. x 11-1/2"L Datalogger is housed in a weather-resistant, stainless steel cylindrical enclosure that fits inside a standard 2"-dia. pipe. Loggers feature automatic barometric pressure and temperature compensation for more accurate readings. Vented submersible pressure transducer is fully encapsulated so moisture can’t leak in and cause faulty data. Includes Windows®and PDA software. Choose from 0-15' (No. 138660) or 0-30' (No. 138661) Range.
