Reliable monitoring of measured values— anytime and anywhere

The new multi-parameter handheld instrument from Endress+Hauser enables easy and reliable monitoring of measured values. Whether it's in a lab or in the field, the Liquiline Mobile CML18 can be used in a wide range of applications and fits in any shirt pocket.


  • Easy operation

    Use your existing tablets and smartphones for operation and commissioning.

  • Benefit from all the advantages of Memosens technology

    Memosens sensors offer you the safest data transmission, the highest measured value availability and total ease of use.

  • Trust your measured values

    Using the same technology for process, laboratory and grab sample measurements provides you with full consistency.

  • Simplify your daily work

    Hot plug & play with pre-calibrated Memosens sensors enables you to rapidly change from one parameter to another.

  • Use it as a data logger

    Save more than 10,000 measured values with time and date stamp.

A talented all-rounder for maximum flexibility

With the Liquiline Mobile CML18, you can measure pH, ORP, conductivity and dissolved oxygen—using just one single device. The current temperature measurement is displayed in parallel. Thanks to digital Memosens technology, switching between different sensors is child's play. Simply replace the sensors directly at the measuring point. The device immediately detects which sensor is connected, automatically loads the saved sensor data and displays the correct measured value directly.

Sensors no longer need to be adjusted onsite and can instead be adjusted in the comfort of a lab or workshop. If you wish to monitor your process over a longer time period, you can use the Liquiline Mobile CML18 as a data logger and store more than 10,000 measured values with a date and time stamp.

Maximum data security thanks to Memosens

The Liquiline Mobile CML18 with Memosens technology guarantees maximum data security, delivering measured values that are 100% reliable. Regardless of where or when a measured value needs to be monitored, the device always supplies values that are correct.


Thanks to Memosens technology, the sensors are equipped with a microprocessor, which is integrated in the head and converts all of the sensor signals to a robust digital signal, making them insensitive to moisture or other environmental influences. Using these reliable measured values, the user can quickly take the required measures and keep the process running under optimized conditions.

Data consistency between lab and process

When analyzing a sample, the use of different measuring technologies can often result in deviations between the lab measurement and the measurement recorded in the process. With the Liquiline Mobile CML18, the same Memosens sensors that are used in the process can also be used in the lab. This guarantees the complete consistency of data between lab and process measurements.


In cases requiring a particularly fast response time, the new robust lab pH sensor, the Memosens CPL51E, is the ideal choice. It uses the same Memosens technology as the process sensors, but is optimized for a fast response time in sample analysis and laboratory applications that do not require a high degree of temperature- and pressure-resistance.

Intuitive operation

The Liquiline Mobile CML18 can be operated easily using the intuitive SmartBlue app. All measured values and sensor data are transferred via a secure Bluetooth connection to the app on your smartphone or tablet. The app provides you with a convenient way to make settings, adjustments and read out sensor values and measured values.


In addition, the Liquiline Mobile CML18 has an integrated, wireless charging function, which enables inductive charging using a Qi-certified charger, just as easily as with your smartphone.
