Case Study - Underground River Monitoring

Fort Stanton Cave in New Mexico has been the subject of exploration for hundreds of years. The ancient underground rivers that formed over 30 miles of passages are little understood, and the Fort Stanton Cave Study Group (FSCSG) was determined to map their behaviour. Tim Frederickson realised they could measure water levels in the famous Snowy River Passage using a sensor with a voltage output. But how to record the results?

“I knew I was looking for something to log data, and I also knew that there were a lot of factors that would make finding something workable very difficult. How do you power something underground that has to take readings over several months or even years? We needed to set up technology in an environment that would have no external power source, up to one hundred percent humidity, and could take an experienced caver as many as twelve hours to reach."  Tim Frederickson, FSCSG

Calibration Assures Accuracy


All EasyLog data loggers can be provided with a calibration certificate

They are calibrated using apparatus traceable to national or international standards

Each logger purposefully tested at the temperatures you will be using it in
