The new MVE Datalogger is a battery operated temperature recorder that provides an easy method to monitor the temperature of cryogenic environments. When mounted to the lid of an MVE Vapor Shipper, these dataloggers will record the temperature of the vessel over the entire course of the shipment. Current temperature and alarm status can be observed on the digital display, while past temperature and alarm data can be extracted via PC and interface cable. In addition, the PC software can be used to set alarm thresholds, set sample rates, and generate graphical reports for electronic or hard copy.
