Bio-loggers WACU

Dernière mise à jour : vendredi 20 février 2015, par Brigitte GAILLARD

Accelerometer logger

This data logger combines PTL measurements (pressure, temperature, light) with 3D acceleration recordings. Extremely low power consumption brings outstanding life time/small and light-weight characteristics, while the 4 GB memory allows users to store a huge quantity of data. Casing is customizable according to the intended use (biocompatible casing for implantation or pressure resistant for deep diving use) ; the size and nature of batteries can be adapted to the application and the temperature conditions.
