About Us

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 production of precision thermometers in our own manufacturing facility, we are involved with all our heart.”


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.”

We help you with your measurement tasks – here is how:

Calibration Equipment

Comprehensive product knowledge
We distribute the calibration products of a single manufacturer. This allows us to offer you expert advice and support, because we know exactly what the devices can and cannot do. This enables you to better evaluate 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 experience in their application 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

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

Family-run company
As a family-run company, 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 sure that our services are provided according to recognized and strict guidelines.

Precision Thermometers

Handcrafted precision thermometers
Our precision thermometers are hand-made in our own manufacturing facility 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 connection cable? We implement your requirements.

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

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 precisely 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 is regularly trained and educated to meet the requirements of the German Accreditation Body (DAkkS) and to always be at the cutting edge of knowledge. This ensures that our training courses meet current standards and that our staff has 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 also ask our speakers questions. In this way, we promote the exchange of information, support learning, and strengthen our customers’ network.
