  • Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.

With Liquiline To Go CYM291 you get the information you need, where you need it. The robust multiparameter handheld enables you to control any measuring point - even in hazardous areas - with the identical Memosens sensors that you use in your process. This guarantees full data consistency between your measurements with results you can trust: reliable measuring values that allow you to quickly take any remedial actions necessary to keep your process running under optimal conditions.


  • Make the right decisions for your process: the handheld's reliable measurements with 100% signal integrity help you to take the appropriate action at the right moment.

  • Trust your grab sample values: using the same technology for process and grab sample measurement provides you with full consistency.

  • Take it to any measuring point: the robust, shock-proof housing with ingress protection to IP66/67 enables fast process control even in the most challenging environments.

  • Simplify your daily work: hot plug & play with pre-calibrated Memosens sensors enables you to rapidly change from one parameter to another.

  • Improve your plant safety and efficiency: even in hazardous areas you can analyze grab samples directly at the sampling point, thus eliminating the risk of sample contamination.
