Heron DipperLog Nano Level Logger

  • Reliable water level monitoring
  • Includes software and download cable
  • Automatic barometric compensation


The dipperLog is a low cost data logger for continuously monitoring water levels and temperature in wells, boreholes and open bodies of water. Its small size allows the dipper-log to be used in well diameters as small as 3/4". It is very easy to launch and even easier to download when used in conjunction with a barLog barometric logger. No need to open separate files, the Heron designed software does it all for you. Because of the unique "grab" of the barometric pressure during set up of the dipperLog there is no requirement for elevation correction. Down in the valley, or on top of a mountain, it is spot on every time.

The Heron dipperLog allows the user-selectable intervals from one second up to 255 hours. A 'log' time reading facility is also included. The first reading starts at one second, there after the time interval doubles with each reading for 255 readings which lasts for nine hours. At this point the logger can be downloaded and reformatted to take a reading every hour without removing the logger from the well (on direct read loggers only). Rapid real time readings, up to 10 readings per second, are stored directly onto a laptop. A real time graph is displayed during the recording/measuring period. There is no limit to the number of data points that can be recorded with this facility.
