And Here Is Our Winner for the Oldest NETZSCH TGA Still in Use

As part of our 60th anniversary, we looked into the history of our TGA in April and asked: Who has the oldest instrument still in use? Now, we’ve found a winner!

The winner is Geiger + Co. in Heilbronn, Germany. Congratulations! Their TGA 209 C Iris® was purchased in 2004 as a demonstration instrument and is still of great help to the company to this day.

Dr. Gudrun Joos-Guba had only been with Geiger + Co for 4 years when the TG 209 was delivered. Since then, she has also been regarded as the contact person for our instrument:

"Mr. Gruener [of NETZSCH] had clarified the appeal of the TG 209 C Iris® to us during regular visits and invitations to events. Since we, as a separator and lubricant manufacturer, pass everything decomposable through the chimney, various modifications were still necessary. The chimney and filter were adapted to our needs. A weighing table for a VibrationA mechanic process of oscillation is called vibration. Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. In many cases, vibration is undesirable, wasting energy and creating unwanted sound. For example, the vibrational motions of engines, electric motors, or any mechanical device in operation are typically unwanted. Such vibrations could be caused by imbalances in the rotating parts, uneven friction, or the meshing of gear teeth. Careful designs usually minimize unwanted vibrations.vibration-free setup was necessary, as the TGA registered the heavy traffic produced on the factory premises and by our cleaning staff.

Thanks to regular maintenance and several general overhauls by NETZSCH Service, the TG 209 Iris still performs as well today as it did on the first day. This shows that the decision in favor of a robust and high-quality measuring device from NETZSCH was the right decision, also from a sustainability point of view.

I am now retiring at the end of August after 22 years with Geiger, but your TG 209 C Iris® will carry on!"

Dear Dr. Joos-Guba, thank you for your contribution!
