Testo 915i Thermometer Smart Probe

The Testo 915i Thermometer Smart Probe is a rapid-response wireless instrument compatible with a range of professional Testo type K thermocouple probes. Due to this large selection of probes the 915i is ideally suited for a wide array of applications such as measuring ambient temperature or temperature in ducts or at air outlets. Choose between immersion, surface, air, and flexible probe heads all with a high measuring accuracy of ±1.0 °C thanks to system calibration ex-works.

One of the most important features of the 915i Thermometer Smart Probe is the innovative locking mechanism within the handle, which ensures probes are securely attached before use. The handle itself is both robust and ergonomically designed, specifically built for enhanced portability and versatility.

The free Testo Smart App, compatible with the 915i Smart Probe, facilitates intuitive operation, evaluation and documentation. Utilise this intelligent app to display readings, construct clear graphical presentations of temperature curves or create and send documentation (PDF or CSV) all whilst still on-site. An automatic Bluetooth connection functions within 100m of smartphones, tablets or Testo measuring instruments such as the Testo 400 and 550s series.

Choice of Probe Heads

Available with various Class 1 plug-in probes, the Testo 915i comes supplied with either an immersion/penetration probe, surface probe, air probe, flexible probe or as a kit with three temperatures probes in a Smart Case. Reliable in any condition, this Thermometer Smart Probe has proven quality and excellent durability.
