Wireless Thermometer with Surface Probe (TC Type K) The latest addition to the wireless Smart Probe family, the Testo 915i with plug-in thermocouple probes, makes temperature measurements even faster, easier and more flexible than before. Thanks to the locking mechanism with compatibility with all Testo and other common Type K thermocouple probes, the Smart Probe can be used in the most demanding applications to complete the job quickly and accurately. With the free Testo Smart App, temperature information is presented in a clear and graphical way for easy tracking and diagnostics. All measurement data can be reported directly from the App and then sent as PDF or CSV files. The Testo 915i connects automatically by Bluetooth to the Testo Smart App on any smartphone, tablet or directly with other refrigeration and indoor air quality measuring instruments from Testo. The Testo 915i is available with various Class 1 plug-in probes: immersion/penetration probes, surface probes, air probes or flexible probes. Testo 915i as a kit, with three temperature probes in a convenient soft case keeps the probes and device safe from the demands of the job.
