RBRquartz³ Q|plus tide and wave recorder

The RBRquartz³ Q|plus can record instantaneous pressure measurements, average pressure samples to remove wave action, and burst-sample pressure at up to 16Hz for wave height and period calculations. Wave measurements are made by burst sampling, with programmable sample rate, number of samples, and burst interval. High accuracy marine temperature data are recorded with each measurement. Wave, tide, and temperature measurements are standard with every RBRquartz³ Q|plus.

Flexible measurement schedules, burst sampling, and configurable integration times permit applications for tide, wave, and sea level measurements. The RBRquartz³ Q|plus has a large battery and memory capacity for extended autonomous deployments and USB, RS-232, or RS-485 connectivity for realtime applications.
