The dipper-log by Heron Instruments is an economical, single channel data logger for long term monitoring of groundwater levels in wells, boreholes and open bodies of water. The dipper-log’s compact size allows it to be used in wells down to ¾ inch (20mm) diameter. The dipper-log uses an absolute (total pressure) system. The system does not require vented cable which is subject to condensation and freezing. The dipper log automatically takes barometrically compensated readings for short term tests.
