Measure reliably and precisely – with us by your side


“I found my calling in the world of metrology and engineering. For more than two decades, I have been passionately dedicated to precise temperature measurement and thermometer calibration.
Our company specializes in various aspects of temperature measurement and calibration. From the setup of state-of-the-art calibration laboratories and the operation of a DAkkS-accredited calibration service to the manufacturing of precision thermometers in our own factory, we put our heart and soul into everything we do.


I enjoy sharing my expertise in seminars with calibration laboratory staff, laboratory managers, project engineers, and developers. In doing so, I place great importance on not just presenting dry facts, but sharing my passion for this field through practical examples from our daily laboratory routine. I am convinced that learning is more effective and much more fun when we support each other.”

This is how we help you with your measurement tasks:

Calibration Equipment

Comprehensive product knowledge
We distribute the calibration products of a single manufacturer. This allows us to offer you expert advice and support, as we know exactly what the devices can and cannot do. This helps you better assess the products and select exactly those that best meet your requirements.

Practical experience in the field
We use ISOTECH products in our own laboratory. As a result, we have practical application experience and can provide you with valuable insights and tips on how to use the products optimally.

Efficient repair options
We have the expertise and skills to perform many repairs ourselves. For you, this means fast and cost-effective service, as you do not have to rely on external service providers.

Calibration Laboratory

Independent calibration laboratory
As an independent laboratory, we can fully align our services with our customers’ needs. We are not bound by specific requirements or restrictions, allowing us to offer you tailor-made solutions.

Family-run company
As a family-run business, we are able to build long-term relationships with our customers, understand their individual requirements, and make decisions independently of external investors or associations.

DAkkS accreditation
Our voluntary accreditation is proof of our high quality standards and our commitment to precise measurement results. You can be certain that our services are performed according to recognized and strict guidelines.

Precision Thermometers

Handcrafted precision thermometers
Our precision thermometers are hand-built in our own factory in Fulda, Germany. This allows us to ensure the highest quality and precision and to customize thermometers according to individual requirements. Do you need specific changes to the handle, connector, probe length, or cable? We will implement your requests.

Wide temperature range
Our thermometers are designed to perform accurate measurements. Depending on the model, they can measure temperatures ranging from -200°C to 1200°C. In practice, this offers you versatile application possibilities and flexibility in temperature measurement.

Optimized design for accurate measurements
We place great importance on developing our own tools and production processes. This ensures that the thermometers work accurately and reliably. Since we do not require external suppliers for design, production, and calibration, we can strictly control the quality of our thermometers.

Temperature Seminars

Extensive experience and expertise
With over 1,600 trained participants, we have extensive experience in training. Our profound knowledge and expertise allow us to convey seminar content precisely and effectively.

Up-to-date expertise
Our own staff undergoes regular training and further education to meet the requirements of the German Accreditation Body (DAkkS) and to always stay at the cutting edge of knowledge. This ensures that our training sessions meet current standards and that our staff possesses the necessary expertise to provide participants with high-quality training content.

Online community for networking and knowledge exchange
Through our online community Klasmeier.Connect, we create a platform where our customers can network. Here, they have the opportunity to share their knowledge with each other and ask our speakers questions. In this way, we promote the exchange of information, support learning, and strengthen our customers’ network.
