From the spring of 2017 the manufacture of the new generation of dataloggers has commenced. This generation picks up after the successful model TMS3. The size as well as the location of the thermometers remains the same, therfore the measuring is identical with the version TMS3. What did change however is the structure, which was improved to decrease the possibility of damage such as the thermometers breaking away due to the fact that up to this generation they have been always located on the surface.
