Model 9200 RRL Remote Radio Link
Available from Solinst Canada Ltd
RRL Remote Radio Link is a wireless system designed to communicate with Levelogger dataloggers, collecting groundwater level, temperature, conductivity, barometric pressure and rainfall data if desired. The RRL sends data from the field, back to the home station and your computer using short-distance radio (20 miles/30km line-of-sight). RRL hardware is interchangeable, making it ideal for small, closed loop monitoring networks.
