PopisThe OM-CP-TRANSITEMP-EC is a low-cost temperature recorder designed to allow the user to easily monitor temperature fluctuations over time during shipment or storage of goods. Each logger can only be started once to monitor temperature during one application (single use). Used data loggers can either be discarded or returned to be refurbished to like new condition so they can be used again. The refurbish charge is $15 for each logger. This all-in-one, compact, portable, easy-to-use device will measure and record up to 8191 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 by holding down a recessed push button.
