The Lovibond® MD610 Multiparameter Photometer provides a versatile and dependable solution for water quality analysis across a wide range of industrial, commercial and environmental applications.


With more than 120 pre-programmed testing methods, the MD610 combines high-performance optical measurement with straightforward operation, allowing users to analyse multiple water quality parameters using a single portable instrument.


Featuring a six-wavelength optical system, Bluetooth® connectivity and extensive data storage, the MD610 provides a practical solution for water treatment professionals, laboratory technicians and field engineers requiring flexible testing capabilities and reliable results across different environments.

Comprehensive Multiparameter Testing

Effective water quality monitoring often requires the measurement of multiple parameters to support treatment control, process efficiency and informed operational decisions.


The Lovibond® MD610 provides access to more than 120 pre-programmed testing methods, allowing users to carry out a wide range of water quality measurements without the need for multiple instruments.


Methods can be selected by name through the menu-driven interface, while a personalised favourites list provides quick access to frequently used tests. Compatibility with tablet, powder and liquid reagents offers additional flexibility across different testing requirements.

Accurate and Reproducible Measurements

Reliable water analysis depends on precise measurements to identify changing water conditions and maintain effective control of treatment processes.


The MD610 uses a six-wavelength optical system with precision LEDs and interference filters to provide accurate and reproducible photometric measurements across its extensive range of testing methods.


The One-Time-Zero (OTZ) function helps streamline routine analysis by reducing repeated zeroing steps for compatible measurements, while on-screen method information supports consistent testing procedures.

Designed for Straightforward Operation

The MD610 combines comprehensive testing capabilities with an intuitive, menu-driven interface, making it suitable for both routine monitoring and more detailed water quality analysis.


Clear on-screen information helps users select the appropriate testing method and identify the required reagents, sample cells and reporting units, simplifying the measurement process.


Frequently used methods can be stored in a personalised favourites menu, reducing the time needed to navigate between tests and helping users carry out regular monitoring programmes efficiently.

Flexible Data Storage and Connectivity

The Lovibond® MD610 combines reliable measurement with practical data management features, allowing results to be recorded, transferred and incorporated into routine reporting processes.


With storage for up to 1,000 measurements, including location ID, date and time information, the instrument helps users maintain organised testing records across different sampling locations and monitoring programmes.


Bluetooth® connectivity enables wireless data transfer to the AquaLX® App, while CSV export and optional PC software provide additional options for reviewing, managing and documenting measurement results.

Adaptable to Specialist Testing Requirements

The MD610 provides additional flexibility for laboratories and water treatment professionals working with specialist methods or application-specific measurement requirements.


Alongside its extensive library of pre-programmed methods, the instrument supports up to 35 user-defined calibration curves, allowing users to adapt testing procedures to particular analytical requirements.


Software updates provide further flexibility by allowing additional methods and instrument improvements to be incorporated as they become available, helping the MD610 support changing testing requirements.
