With testo 570s, Testo, the global market leader in measuring devices, is launching the world's first intelligent cold analyzer that detects and highlights anomalies autonomously in the testo Smart app. With it, Testo is revolutionizing long-term measurements on refrigeration and air conditioning systems and heat pumps. Testo 570s has the longest battery life in the world, up to 360 hours!
A combination of intelligence, precision and endurance
Especially on long-term measurements, error analysis often takes a long time and anomalies often remain undetected. Thanks to the digital fault analysis in the testo Smart App accessible via Bluetooth and its large memory capacity, the new testo 570s cold analyzer detects faults quickly and reliably. This not only makes it possible not to forget anything, but also to save a considerable amount of time.
Testo 570s also offers new advantages for standard measurements. The hybrid system consisting of a rechargeable battery and an accumulator is another world first and allows a record autonomy of 360 hours to be achieved. Additionally, the accuracy of pressure measurement has been increased to 0,25% of span, providing more reliable results even for systems operating at low pressures.
Quick and easy to measure
In order to offer professionals a device that allows them to perform measurements as quickly and easily as possible, Testo has developed numerous functions that make their daily work easier. Testo 570s is equipped with:
. a large screen which offers a quick overview of all measured values as well as a graphical display,
. stored programs which guide the operator throughout the measurement process and allow many installation parameters to be automatically determined,
. wireless probes that automatically connect to the device, via Bluetooth, for simple measurement of temperature, vacuum and electrical consumption or power.
In addition, the testo Smart App allows users to comfortably and easily configure, measure, document and view the measurement data recorded by the testo 570s analyzer on their smartphone or tablet.
Equipped for every challenge today and tomorrow
When it comes to robustness, Testo relies on proven quality. With an IP54 protection rating, testo 570s achieves reliable results even under the toughest conditions.
It can be used on installations using A2L fluids and it is the only device on the market already suitable for A3 fluids which will be the majority in your installations of tomorrow.
