The Datalogger Type 575-II is the successor model of the long-standing field-proven Type 575 for measuring and recording water level and temperature in groundwater wells and surface water stations. First, the slimmer diameter of 22mm catches the eye, now this Groundwater Datalogger can also be used in 1-inch groundwater observation wells. In addition of a large flash memory, the circuit has been designed to extremely low power consumption. Therefore, we can now make an extended promise: 10 years and 3 million measurements without replacing the battery!
The operating concept was also revised with this new groundwater datalogger. From now on, HT Dataloggers can be excellently operated on touch displays, without touch pen and without keyboard.
