The Testo 925 Type K Thermometer is a 1 channel temperature measuring instrument which is particularly suitable for applications in the HVAC field. The instrument is optimum for the connection of fast and reliable thermocouple probes. Using measurement data transfer by radio, the measurement value of a further temperature probe can be additionally displayed wirelessly. The protective cover TopSafe ensures water and dirt proofness when a probe is connected. The instrument reliably and continuously displays the minimum and maximum measurement values. The measurement values shown in the display (current measurement value, frozen measurement value, or the minimum/maximum values) can be printed out via the Testo report printer (optional). The user can store limit values in the instrument himself; as soon as these upper and lower values are violated, an audible signal sounds.
