Measuring instruments for refrigeration technology from Testo

Fully automatic

Fully networked

Networked systems that work together seamlessly make your work on refrigeration, air conditioning and heat pump systems much easier and more efficient. With just one click, all measurement data can be viewed centrally in the manifold or the testo Smart App. This also greatly simplifies the documentation process, which can be carried out directly on site.
