The Testo 115i is a pipe-clamp probe that measures temperature in pipes more accurately than thermocouples, thanks to superior NTC temperature sensor technology. The exclusive Testo probe design grips pipes up to 1.5” in diameter, and maintains critical contact between probe and pipe surface to derive the best readings.
The Testo 115i works with an App and Bluetooth so you can read it out on a smart phone or tablet. The Testo Smart Probes App allows users to remotely read measurements from up to six (6) Smart Probes, and easily document and report the results. The app also features automatic calculations.
