Energoconsult Posted November 27, 2013 Report Share Posted November 27, 2013 Hi, I have data loggers - 11pcs. Can someone please tell me how to find out witch is the year of manufacture of every single of the Symphonie?! I have only serial numbers! The first i bought in 2006, and the last one in 2012, but cant see difference. Thanks in advance! Link to comment Share on other sites More sharing options...
