LAQUAtwin B-722 is a pocket waterproof sodium meter with a large LCD display incorporating HORIBA world's unique flat ion electrode designed for micro-volume measurement. The replaceable electrode utilises the same principle than traditional sodium ion selective electrode (ISE) but the B-722 requires only a few drops (0.3 ml) to enable quick and accurate analysis. The sodium concentration of samples such as liquids, pastes, powders can be measured and the B-722’s sensor enables direct evaluation of sodium concentration from solid sample. Large volume samples can also be measured easily by immersing the measuring cell. Finally, an absorbent sampling paper allows measurement of sample from 50 μl. The meter’s large measuring scale (23 to 2,300 ppm) allows to measure high concentration without having to perform a dilution. The B-722 does not use reagent. B-722 LAQUAtwin offers a great simplicity and reliability. It takes just few seconds to perform a measurement making these instruments ideal for field-testing. LAQUAtwin meters are suitable for laboratory professionals and technicians working on production sites.
