High accuracy (±0.01%) pressure and temperature sensors are rated to 1,000m water depth and there is a wide range of sampling regimes and rates at 1, 2, 4, or 8Hz. Continuous logging and output of data is available on demand via external instrumentation or in a burst pattern where data are obtained for a short period before the instrument goes into 'sleep' mode, thus conserving power and memory. There is also a conditional sampling mode where output is regularly monitored but is only logged when data values exceed a customer-set trigger value.

Standard memory is 8 megabytes, representing a storage capacity of 1.4 million records.
