Testo 115i Clamp Thermometer – Bluetooth Smart Probe

The Testo 115i is a Bluetooth clamp thermometer built for HVAC and refrigeration technicians who need fast, accurate pipe surface temperature readings without interrupting the system. Simply clamp it to the pipe, open the testo Smart Probes App on your smartphone or tablet, and get live flow and return temperature readings — logged, graphed, and ready to export as a PDF report.

Ideal for servicing and troubleshooting air conditioning and refrigeration systems, the 115i measures surface temperatures on pipes up to 130mm diameter. It works seamlessly as part of the Testo Smart Probes range — pair it with the Testo 605i thermohygrometer for complete ambient and pipe temperature diagnostics on the one app.
