This compact and easily transportable set contains the most important measuring instruments for refrigeration engineers: the testo 549i high-pressure measuring instrument and the testo 115i clamp thermometer (two of each).
Advantages of the testo Smart Probes Refrigeration set
The measuring instruments can be connected quickly and easily to your smartphone or tablet via Bluetooth for App-controlled servicing and troubleshooting on refrigeration systems, air conditioning systems and heat pumps. Operation of the measuring instruments is state-of-the-art and extremely easy. Both the testo 115i and the testo 549i can be set up quickly and easily, directly at the temperature measuring point or pressure connection. They also make working on widely spaced measuring points considerably easier thanks to wireless connection to a smartphone or tablet. Also practical: no hoses are required for measurements, meaning that no or only very little refrigerant is lost. The handy testo Smart Case enables the measuring instruments to be conveniently transported and ensures that they are always to hand when they are needed.
Practical App with special functions for measurement data analysis on your smartphone or tablet
Measurement data is transmitted wirelessly from the measuring instruments to the testo Smart Probes App and can be viewed conveniently on mobile terminal devices – either as a chart or in table form. The App also offers practical functions such as automatic calculation of evaporation and condensation temperatures, calculation of individual system parameters on air conditioning systems or measurement of the flow and return temperature. 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.
