Memory and Power

The amount of memory available depends upon the model. All RBR Data Loggers are equipped with either 8MB (generation 1) or 128MB (generation 2) of non-volatile flash. This provides sufficient memory for 2.4M readings at 3 bytes per reading per channel or 30M readings at 4 bytes per reading per channel.

The data retention of the non-volatile flash is considered to be 20 years at normal temperatures.

Power consumption can vary significantly depending on the complement of sensors, sampling rate, temperature of the water and whether averaging is used. The Ruskin Software includes a calculator that will automatically estimate the power consumption and memory usage for the deployment settings that you choose. You may download, install, and run the software without a real instrument attached to your PC, and simulate these calculations for any logger/sensor combination.
