Heron barLog Description:

The Heron Instruments barLog, barometric logger is used to automatically compensate readings stored on the dipperLog for changes in barometric pressure. The barLog, with readings every 1 hour and a memory capacity of 128,000 data points,  is recommended for long term monitoring or where more than one logger is deployed within a 5 km radius.

The dedicated, intuitive software makes the dipperLog quick and easy to program and launch. Simply recover your data, save your findings in a tabular display and graph, view both parameters side by side in a split screen.
