Testo 115i Smart Thermometer Probe (0560 1115)


The handy Bluetooth clamp thermometer Testo 115i, in combination with a smartphone or tablet, is suitable for service and error detection on air conditioning and refrigeration systems, as well as for their installation.

In addition to this, the measuring instrument can be used to measure flow and return temperatures.

When working at temperature measurement locations which are far apart, the testo 115i makes the application considerably easier – thanks to a wireless connection to a smartphone or tablet.

And if the Bluetooth high-pressure measuring instrument testo 549i is used simultaneously, individual refrigeration system parameters such as superheating can be calculated. Users can read off their measurement values comfortably in the App installed on the end device. All measurement data are presented either as a diagram or in tabular form. The measurement protocols can then be directly sent as PDF or Excel files.
