The dipperLog VENTED, from Heron Instruments, is their most convenient and labour-efficient solution for groundwater monitoring. Equipped with a vented (gauged) pressure transducer, it automatically compensates for changes in atmospheric pressure, eliminating the need for a separate barometric data logger and simplifying data collection.
The logger is suspended on a direct-read vented cable, maintaining a constant connection between the data logger and the wellhead. This allows users to programme the logger, download data, and start or stop monitoring without removing the instrument from the well, reducing field time and operational costs.
Simply connect a laptop or Windows device at the wellhead to access, manage, and retrieve data while the logger remains deployed. This streamlined approach makes the dipperLog VENTED an ideal choice for reliable, hassle-free groundwater monitoring.
