SonoTT™ SkyLark Series


With the SonoTT™ SkyLark Series, em-tec MEDICAL presents a new range of flow measurement boards designed for the integration into life-sustaining, liquid-bearing medical devices such as HLM, ECMOs, or organ transport systems.

MDR ready: The integrable evaluation electronics incorporate advanced features and an extended error log, enabling a safer and more user-friendly integration of the increasing requirements within medical technology.

2-in-1-function: The newest SonoTT™ SkyLark gold variant additionally incorporates a bubble detection feature through a CAN Interface. This, and its high level of customization based on customer requirements, provide more convenience and safety throughout the entire running processes.

Customization: To ensure a proper and seamless function, the SonoTT™ SkyLark is combined and configured with a customer-specific em-tec sensor such as the SonoTT™ Clamp On SL.

Please note: The SonoTT™ SkyLark is for integration into a medical device and thus not an independent medical device. Not all products are available and approved in every country. Please contact your local distributor, if you have any questions.


Customer-specific sensors and boards for the integration into existing extracorporeal systems such as:

  • Heart-lung machines
