The OM-CP-QUADRTD temperature logger is a 4-channel, battery powered, stand-alone, RTD based precision temperature recorder. This is an all-in-one compact, portable, easy-to-use device that will measure and record up to 21,845 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 OM-CP-QUADRTD makes data retrieval quick and easy. Simply plug it into an empty COM port and the easy-to-use Windows software does the rest.
The Windows software converts your PC into a real time strip chart recorder. Data can be printed in graphical or tabular format and can also be exported to a text or Microsoft Excel file.
