The development of the ECO-Line consciously focused on the essential functions of measurement technology. The pure act of measuring, with an emphasis on precision, speed, and reliability, packaged in a compact housing, enables an outstanding price-performance ratio. Equipped with a hygienically easy-to-clean housing and Auto Hold/Timer function, it is optimized for use in hygiene-critical applications (food, laboratory, pharmaceuticals) or for monitoring in drinking water systems, for example, for legionella prevention. The penetration probe variants ensure either minimally invasive or robust core temperature measurements. Additionally, the handheld devices impress with their ergonomic design, dust and water protection according to IP 65/67, and the illuminated display. Complete device including probe and test protocol with maximum overall precision, alternatively available with a factory calibration certificate.
