NTC Stub Temperature ProbeIncludes:1 x NTC temperature probe 0628 7510, for the testo Saveris 2-T2 Wi-Fi data logger.Features:NTC temperature probe with short probe tube (stub probe)Thermistor NTC temperature probe with short probe tube (stub probe)Measuring range: -4 to 158 °F (-20 to +70 °C)The Testo stub probe is suitable for air temperature measurements and also for temperature measurement in liquids and pastes. Because of the NTC sensor element, the probe provides precise temperature measurements with an accuracy of up to ±0.2 °C/F.The temperature probe features a rounded tip with a short probe tube, is 35 mm in length. With this probe you are ideally equipped for measuring temperatures in close proximity to the testo Saveris 2-T2 Wi-Fi data logger, with no probe cable required.Protection class IP 54 means that the stub probe is splash-proof.The stub probe is rated protection class IP 54 (splash-proof).*For air temperature measurements, the response time is about 40 – 60 times higher than the indicated value measured in water. If you should require a slow-response temperature probe to measure air temperature, this probe is particularly appropriate because it does not take brief temperature peaks into account, or only to a very small degree, when measuring temperature. For example, if you are planning to use this probe to measure air temperature in the refrigerator, briefly opening the refrigerator door would not take into account the temperature fluctuation which results from mixing the warm room temperature with the refrigerator temperature.If you need an air temperature probe with a fast response time, your best choice would be the exceptionally fast temperature probe 0602 0493 which has a large measuring range. This temperature probe can be connected to the testo Saveris 2-T3 Wi-Fi data logger.
