“The calibration of the Eupry temperature loggers is both easy and quickly done. I received a box by mail with the new propers and batteries. Everything worked and fitted as it should and the reliability of the loggers was proved. It took me under an hour to calibrate about 40 loggers – including the time it took to find the refrigerators. The Eupry loggers are important for each of our departments in keeping a high quality of all freezers and refrigerators. I can recommend Eupry to anyone.”
