Here, we continuously create new solutions, expand temperature ranges, test under real-world conditions, and optimize usability. Our current measurement range from 95 °F to 507 °F (35 °C to 264 °C) is the result of intensive R&D and close collaboration with our customers.

We place great importance on flexibility: our products are not only manufactured to the highest quality standards but are also tailored to specific applications. From rugged, long-lasting solutions in mechanical engineering to sensitive monitoring in cleanroom environments – we offer the right indicator for every challenge.
