Testo 115 i - Pipe-clamp Thermometer Smart and Wireless Probe

The testo 115i Smart Probe is a pipe-clamp probe that measures temperature in pipes more accurately than thermocouples because of the superior NTC temperature sensor technology. The exclusive Testo probe design grips pipes up to 1.5” and maintains critical contact between probe and pipe surface to derive the best readings.


Key Features:

  • Measures temperature of pipes in heating and cooling systems
  • Use with testo 549i Refrigeration Pressure Probe to calculate superheat and sub-cooling
  • Quickly identify temperature changes by monitoring real-time trending and data logging
  • 115i NTC temperature sensor is more accurate and stable than thermocouples



Users can read the measurements using the testo Smart Probes App installed on their smart device. The testo 115i works on smart devices with either Android or Apple operating systems at distances up to 60’. The testo Smart Probes App is a powerful and easy-to-use tool. It allows you to remotely read measurements from up to six (6) Smart Probes and easily document/report the results. Automatic calculations make it a snap!

All measurement data is displayed as instrument readings. tables. or graphs. The measurements can be quickly saved as PDF or Excel files. The App creates custom reports which can be saved and/or shared by email. All your data can be stored and retrieved saving you hours of time consuming paperwork!
