The robust, waterproof surface probe (Pt100) can be used to accurately determine the temperature on surfaces. The probe has a wide measuring tip, making it particularly practical for surface measurement. Thanks to its high precision, the probe is suitable for use in laboratories. In conjunction with a corresponding measuring instrument (e.g. testo 735), it is also compliant with EN 13485 and HACCP. The probe is therefore also ideal for applications in the food sector.
