The MD610 gives you a mobile device in a modern design with the analytical features of a laboratory photometer. All important water analysis parameters from A(luminium) to Z(inc) are covered. Combined with the high performance precision of Lovibond reagents, a reliable and quick analysis of water samples is guaranteed. Reagent tablets, powder reagents, liquid reagents, or cuvette tests are used depending on the method.


The IRIM (Infra-red data transmission module) uses modern infra-red technology to transmit data from the MD610 to one of 3 optional interfaces. This allows the MD610 to be connected to a computer or printer.


The AquaLX® app, available free of charge, offers the possibility of transferring measurements to smart phones or tablets via Bluetooth®. The data management then enables analysis and export as a CSV file or graph via email. The app is available free of charge for AndroidTM and iOS®.


The verification standard kit for the MD 610 is designed to assure the user of the accuracy and the reliability of the results related to the integrated wave lengths. The shelf life of the verification standard kit is two years from the date of production, provided that storage and use are in accordance with the instructions provided.
