The Testo 115i Pipe-Clamp Thermometer Smart Probe is a wireless pipe temperature sensor with extended Bluetooth range of up to 350 feet. The 2nd generation model measures temperature in pipes more accurately than thermocouples because of the superior NTC temperature sensor technology. The exclusive Testo temperature clamp probe design grips pipes with diameters of 0.25″ to maximum 1.5″ and maintains critical contact between probe and pipe surface to derive the best readings.

The Testo 115i clamp thermometer is the ideal temperature measuring instrument for carrying out servicing and troubleshooting on refrigeration, air conditioning and heating systems, as well as for installing them. It can also be used to measure flow and return temperatures.

When it comes to measuring temperature at widely spaced measuring points in particular, the Testo 115i pipe clamp thermometer probe makes things a lot easier – thanks to wireless connection to your smartphone or tablet. When used in conjunction with the Testo 549i pressure measuring instrument (sold separately), individual refrigeration system parameters can also be calculated. The Testo 115i works on smart devices with either Android or Apple operating systems, wirelessly transmitting the measurement data via Bluetooth.
