Discover the unseen.

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

Find anomalies with ease thanks to intelligent error analysis in the testo Smart App.

• Reliable diagnoses for long-term measurements thanks to smart error analysis
• Extra long battery life of 360 hours via internal Li-ion rechargeable battery and auxiliary 3xAA
• Large built-in data memory onboard for on-site logging of key parameters

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

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

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.

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

• Suitable for use with A3 and A2L refrigerants
