The OctRTD is an 8 channel, battery powered, stand alone, RTD based temperature recorder. This is an all-in-one compact, portable, easy to use device that will measure and record up to 10,922 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 OctRTD makes data retrieval quick and easy. Simply plug it into an empty COM or USB port and our user-friendly software does the rest.
