Discover the unseen.

Our new digital manifold testo 570s detects anomalies with limitless power. For easy long-term measurements with reliable diagnosis.

The smart solution for long-term measurements

Reliable diagnoses through convenient long-term measurement with intelligent error analysis in the testo Smart App.

This alerts you to anomalies immediately, without a long search and gives you insights of all measurement values from temperature, pressure, to electrical parameters.

Always one step ahead – for the challenges of today and tomorrow


Never run out of power! With a class-leading battery life of 360 hours and a hybrid charging system.


Time is money? Correct! The evaluation of long-term measurements in particular often requires a lot of time. Thanks to intelligent error analysis of the testo 570s, anomalies are detected automatically without a long search.


More and more refrigeration systems operate in the low-pressure range. Therefore, we have increased the measurement accuracy to 0.25% fs.


Flammable refrigerants are becoming more and more common. The testo 570s can be safely used even with A3 refrigerants.
