Flat Sensor pH, Conductivity and Ion Compact Meters Improvements

After more than 25 years manufacturing the Cardy series compact meters, with patented flat sensor technology, HORIBA (UK) is launching its latest generation - the LAQUAtwin.

The LAQUAtwin range is made up of a wide selection of pocket size meters equipped with HORIBA’s exclusive flat sensor technology. The range of meters can measure pH, conductivity, salt (NaCl) and nitrate, sodium, potassium and calcium ions.

The sensor utilises the same measurement principle as traditional electrodes but the LAQUAtwin meters require only a single drop (0.3 ml) of sample to enable quick and accurate measurement, ideal when the sample size is critical.

The wide measurement range allows direct measurement, making sample dilution unnecessary. These reagent-free meters can be calibrated in 1 or 2 points and feature automatic temperature compensation functions. The LAQUAtwin sensors are suitable for many different types of micro samples, such as liquids, pastes, powders and solids. At the end of the sensor’s useable life, it can simply be replaced; you don’t need to replace the complete meter.

The waterproof casing (IP67 rated) allows robust measurement even in wet conditions so these meters can be safely dipped to measure large volume samples.

User-friendliness and reliability are key benefits, making these meters ideal for onsite and field-testing. They are designed for professionals, working in a laboratory or on production sites, as well as for personal use.

The pH and conductivity meters are suitable for measuring basic properties of water in various industrial sectors while the salinometers are particularly useful for checking the salt content of food. In agriculture, the meters are ideal for quick on-site diagnosis of soil and plant sap characteristics to improve fertilisation and crop yields.
