Testo 115i Smart Probe Pipe Clamp Thermometer

The Testo 115i Smart Probe is a pipe clamp thermometer that can connect your phone or tablet to wirelessly monitor and record temperatures in cooling, heating ,and refrigeration applications. The 115i has a temperature measurement range of -58 to 302 °F (-40 to 150 °C), and measurements can be made on pipes with diameters from 0.25 inches to 1.5 inches. The NTC temperature sensor on the grippy clamp jaws ensure that your results will be more accurate and stable than with a thermocouple. When you use the 115i along with the Testo 549i Refrigeration Pressure Probe, the free app can automatically calculate superheat and sub-cooling.

The free Testo Smart Probes App is available for iOS 8.3 or newer and Android 4.3 or newer. Up to six Testo Smart Probes can be connected through Bluetooth at any time, and the probes will work at distances up to 60 feet. The Testo Smart Probes App enables the user to graph and filter measurements and create reports either in excel or PDF format. The 115i is also sold as a part of both the Testo Hydronic Heating Smart Probe Set and the Test Refrigeration Smart Probe Set.


The Testo 115i comes with 2 Year Warranty.
