testo 115i – Smart Clamp Meter

Combined with a smartphone or tablet, the testo 115i clamp thermometer is the ideal temperature measuring instrument for carrying out servicing and troubleshooting on air conditioning and refrigeration systems, as well as for installing them. It can also be used to measure flow and return temperatures. 

- Measurement of the flow and return temperature of heating systems
- Measurement of temperatures in refrigeration systems in order to calculate superheating and subcooling
- Easy to use at measuring points that are far apart
- Rapid detection of temperature changes via graphical progress display 

Professional measuring technology is now mobile: when it comes to temperature measurements at widely spaced measuring points in particular, the testo 115i makes things much easier – thanks to a wireless connection to the smartphone or tablet. When used in conjunction with the testo 549i pressure measuring instrument, individual refrigeration system parameters can also be calculated. 

Measuring using the App offers lots of advantages 

Measurement data is transmitted wirelessly from the clamp thermometer to the testo Smart Probes App and can be viewed conveniently on your smartphone or tablet – either as a chart or in table form. Temperature changes are therefore immediately evident. The measurement data log can be emailed directly as a PDF or Excel file. This saves you time, allowing you to further increase your efficiency.
