The new "Extended heating rates" module for the EMI III heating microscope software offers you the possibility to heat your specimens up slowly while still in a controlled manner. This option is put into effect by switching the units of the heating rate from Kelvin per minute (K/min) to Kelvin per hour (K/h). With the new module, you can reduce the minimal heating rate from 0.1 K/min to 0.0017 K/min, or 0.1 K/h respectively.

Low heating rates like these are of interest for all users, who want…

Heating microscopes can be used for a wide range of tasks. In order to provide our customers with a detailed insight into the capabilities of the EM301 heating microscope, we have created a new series of application reports on the topics of materials characterisation, instrument characteristics, and the investigation of the influence of measuring parameters. The reports are based on an extensive series of example measurements that were carried out in our laboratory.
