Main features

Comparison of EMI 2 and EMI III

The EMI III heating microscope software was developed based on Hesse Instruments’ tried-and-tested EMI 2 image analysis software. The full functionality of EMI 2 has been included in EMI III, and the range of functions has been expanded to boost ease-of-use and to provide additional options for the preparation, performance and evaluation of measurements.

In addition to the expanded range of functions, EMI III improves upon EMI 2’s performance considerably. The software has been designed for current operating systems and hardware and therefore permits, among other things, more accurate resolution during image analysis and greater storage capacity for silhouettes of the test piece.

Scope of supply and installation of upgrade

In order to guarantee the improved performance of EMI III, the upgrade to this version includes not only the EMI III heating microscope software but also the following hardware and software components:

  • Measuring station computer: EMI III comes installed on a preconfigured and ready-to-use measuring station computer. In addition to the operating system and heating microscope software, the computer is equipped with all of the necessary hardware interfaces.
  • Network-compatible CCD camera: A more powerful camera with faster transmission delivers images in the necessary resolution for the newly developed evaluation algorithms. The camera is compatible with the existing macro lens of the EM201.
  • Temperature acquisition device or ModBus module: Depending on the needs and conditions, the Hesse Instruments furnace control is equipped with a new temperature acquisition device or a new ModBus module for communication with EMI III.
  • EMI 2 – Data import module: The upgrade to EMI III includes a data import module that allows you to import and examine EMI 2 measurements in EMI III.

The upgrade installation is designed and documented so that you can easily carry out the process yourself. After a single adjustment procedure, the upgraded heating microscope is ready for use.
