Horiba LAQUAtwin B-771 Conductivity Meter

pocket-sized conductivity meter / two calibration point classes / IP67 protection / direct measurement of liquids and solids / battery

The LAQUAtwin B-771 conductivity meter (conductivity/salinity/TDS) is waterproof with a large LCD display. This conductivity meter incorporates a flat electrode, unique in the world, designed with the latest HORIBA technology for microvolume measurement. The replaceable electrode uses the same measurement principle as the traditional conductivity electrode; however, the B-771 only requires a few drops (0.12 ml) to provide a quick and accurate analysis.

The conductivity of a sample can be easily assessed by placing the sample directly in the sensor. On the other hand, the B-771 can be used as a traditional conductivity meter by immersing the electrode in a liquid.

The LAQUAtwin B-771 conductivity meter is reliable and very easy to use. It takes just a few seconds to provide a result, making it an ideal instrument for field analysis. The LAQUAtwin conductivity meter is perfect for laboratory professionals and field technicians. This tool can be useful for decision-making during quality inspections, as it provides immediate assessment of conductivity value in many applications.
