The Lolog range of single-parameter data recorders offers three types of input (digital, analogue and internal pressure).
It is very compact and is thus easily installed out of sight. The Lolog range is battery operated, rated IP68, and has a Winfluid software interface. The batteries allow standalone operation for 5 years, at the rate of one value recorded per minute. It is very easy to install in small spaces (meter housings, piezometers).
The Lolog is extremely useful for drinking water system diagnostics, or for analyses of abstraction feeder basins, with piezometer level monitoring, and its reinforced ABS case is very light and strong (IP68)
