The Bridge120 is a battery powered, miniature, stand alone bridge/strain recorder. The device features a 20Hz processing speed and a real-time clock module. This easy-to-use device can measure and record up to 32,767 measurements per channel. The storage medium is non-volatile solid state memory, providing maximum data security even if the battery becomes discharged. The device can be started and stopped directly from your computer and its small size allows it to fit almost anywhere. The Bridge120 makes data retrieval quick and easy. Simply plug it into an empty COM or USB port and our user-friendly software does the rest.
