testo Smart Probes AC & refrigeration test kit - with smartphone operation

Order-Nr.  0563 0002 02

  • Fast and simple installation of the testo 549i high-pressure measuring instrument directly onto the pressure connection

  • Low refrigerant loss thanks to hoseless application

  • Automatic calculation of evaporation and condensation temperatures and simple selection from more than 80 refrigerants via testo Smart App

  • Large testo HVAC softcase: store additional testo Smart Probes for further applications in the heating, air conditioning and ventilation field safely

The testo Smart Probes AC & refrigeration test kit is ideally suited for testing air conditioning and refrigeration systems and installing them. The large testo HVAC softcase enables the measuring instruments to be conveniently transported and ensures that they are always to hand when they are needed.


Product Description

This compact and easily transportable kit 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), along with a testo softcase for up to 7 further testo Smart Probes.

Advantages of the testo Smart Probes AC & refrigeration test kit

The measuring instruments can be connected quickly and easily to your smartphone or tablet via Bluetooth®. This means they enable the App-controlled testing of heat pumps, refrigeration and air conditioning systems. Operation of the measuring instruments is not only state-of-the-art, but also intuitive. Because both the testo 115i and the testo 549i can be quickly and easily fitted directly onto the temperature measuring point or pressure connection. They also make it considerably easier to work on measuring points that are a long distance apart, thanks to Bluetooth connection to a smartphone or tablet. Also practical: no hoses are required for measurements, meaning that only very little refrigerant is lost. You can comfortably transport up to 11 testo Smart Probes in the large testo HVAC softcase, and they are always to hand when you need them.

Practical App with special functions and for measurement data analysis on your smartphone or tablet

Measurement data is transmitted via Bluetooth from the measuring instrument to the testo Smart App and can be read out conveniently on mobile terminal devices – either as a diagram or in table format. In addition, the App offers practical functions, such as the automatic calculation of superheating and subcooling, or the calculation of the cooling or heating output of more than 80 refrigerants. Finally, the measurement data report can be sent directly by e-mail as a pdf or csv file (e.g. with Excel). This saves you time, allowing you to further increase your efficiency.
