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).
