For precise temperature measurements: use the robust air probe with exposed sensor (NTC) with the compatible measuring instrument (please order separately) to measure the ambient air temperature. Robust air probe (NTC) – equipment and areas of application Use the fixed cable to connect the robust air probe to the measuring instrument (please order separately). The air probe is equipped with a high-quality NTC sensor, is easy to use and features high measuring accuracy of up to ±0.2 °C. The robust air probe is designed for ambient air temperature measurements and offers numerous application options. Thanks to the exposed NTC sensor, you can obtain the reading within a short response time. The robust air probe really comes into its own, for example, when checking the indoor air temperature in buildings and refrigerated rooms.
