New Data Logger Designed to Fit into 2” Bore Holes for Use when Monitoring Ground Water
Jan 21 2011
The AquaLogger is compatible with both the Aquaprobe range and the AquaPlus Optical DO probes from Aquaread (UK). The instrument will log all parameters that the connected probe is measuring, such as dissolved oxygen, pH, conductivity and turbidity.
The AquaLogger and connected probe are powered by 2 standard ‘C’ cells; these batteries provide enough power for up to 6 months continuous logging, depending on the logging and event trigger frequency.
Long Logging durations can yield large amounts of data; this is not a problem for the AquaLogger as there is enough memory for 32,000 datasets! A single dataset can consist of up to 20 different measured parameters when using the AP-1000 for example, and includes the GLP calibration records for each electrode.
Every AquaLogger comes with a LoggerLink software CD. This simple user interface allows users to set logging frequencies, manage their data and to customise the event trigger feature. The software offers many neat features such as:
- The ability to output selected data into a text report displaying highs, lows, averages and all the actual readings.
- The opportunity to output the data in an Excel file for manipulation into graphs.
- Memory management allowing users to save recordings to file in order to clear the instrument’s memory regularly.
- The very useful logger status window which provides some vital, real time information when the AquaLogger is connected. It will not only display how many days battery life is left, but also how many days memory is remaining. These values adjust in real time as the settings are changed, so users will always know how long the instrument can be deployed.
- Event triggers can be set in the Logger setup screen, once set this will increase the logging frequency of the selected parameter to the pre-set level by the user, allowing extra data to be captured exactly when it’s needed.
“Both the Aquaprobe and the AquaLogger measure in at under 2” diameter making them the ideal choice for use in bore holes found at ground water monitoring sites. The extra steel cable support wires take all the weight of the cable and probe, meaning long cable lengths of up to 100m can be used safely, with no stress to the connectors!” says Aquaread’s Managing Director.
