## Description

LAQUAtwin 743 is a pocket waterproof nitrate 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 nitrate ion selective electrode (ISE) but the B-743 requires only a few drops (0.3 ml) to enable quick and accurate analysis. The nitrate concentration of samples such as liquids, pastes, powders can be measured and the B-743 sensor enables direct evaluation of nitrate 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 (62 to 6,200 ppm) allows to measure high concentration without having to perform a dilution. The B-743 does not use reagent. LAQUAtwin B-743 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-sites. It can be used as a quick decision making tool delivering instantaneous assessment of nitrate concentration. Measurement principle: Ion Selective Electrode Minimum sample volume: 0.3mL Measurement range Range and Resolution 0 to 99ppm : 1ppm 100 to 990ppm : 10ppm 1000 to 9900ppm : 100ppm Calibration: Two-point Accuracy: ±10% of reading value.
