Smart Tools– Refrigeration Set

The testo smart tools  refrigeration set is a combination of four instruments to measure high-side and low-side pressures and temperatures of A/C and refrigeration systems. Configured to be used during commissioning, servicing, PM and troubleshooting A/C and refrigeration systems. This kit can be operated with no tools other than your smart phone to communicate with the instruments.

The advantages of the testo smart 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

The testo Smart Probes App is a powerful and easy-to-use tool. It allows you to remotely read measurements from up to six (6) Smart Probes and easily document/report the results

Practical App with special functions for measurement data analysis on your Smartphone or Tablet

Measurement data is transmitted wirelessly from the relevant measuring instrument to the 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 timed and multi-point mean calculation, volume flow configuration or a pressure drop test. 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.

System requirements:

- iOS 8.3 or later
