Marathon Products offers liquid nitrogen data loggers with large LCD displays for real-time viewing and data capture. The palm-sized LN2 logger with NFC-enabled circuitry allows users to read and download -200˚C profiles to Android smartphones. Users can view all critical data from the display and then send via email. PDF files can be automatically generated and saved by simply placing the phone directly above the LCD display. Users can view critical temperatures in real time without interrupting data logging functions and save it to the phone. In addition, data from the -200˚C loggers can be saved to a 21 CFR database, programmed directly to a PC.
