Hesse Instruments around the world

Our products are manufactured in Germany before being sold across Europe, Asia, and North and South America. These sales are supported by a network of long-standing and reliable distribution partners. To ensure the best possible service for customers in their local area, our partners can provide practical support and advice on our products’ operation thanks to their teams of competent and trained technicians.

Company History

Hesse Instruments was founded by Dr Axel Hesse in Osterode in 1992. Originally operating as a two-person team, the engineering firm aimed to advise customers in various practical areas of materials testing and to develop software with accompanying measuring technology for thermal analysis instruments. Among other things, solutions were created for dilatometers, fire resistance under load apparatus, hot bending apparatus, the evaluation of Weibull statistics, and the Leitz heating microscope.

In 2000, Dr Hesse acquired the heating microscope formerly manufactured by Leitz (or Leica from 1998 onwards) – a world-famous instrument that had proven its worth over many decades. The instrument underwent a thorough technical overhaul and was made available worldwide in an updated form as the EM201 heating microscope from 2001. Development continued steadily over subsequent years.

In 2015, Hesse Instruments launched the new EMI III heating microscope software, which is now installed as standard in new EM301 instruments and sold around the world. Following in the footsteps of the EM201, the EM301 is the only current successor to the renowned Leitz heating microscope.

Today, we are a small, dedicated team with skilled engineers and technicians. We use our knowledge and experience to create high-quality products – for the long-term satisfaction of our customers.
