Salinometer LAQUAtwin B-771

Pocket-sized salinometer / two calibration point classes / IP67 protection / direct measurement of liquids and solids / battery

The salinometer (conductivity/salinity/TDS) LAQUAtwin B-771 is waterproof with a large LCD screen. This salinometer 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 evaluated by placing the sample directly in the sensor. On the other hand, the B-771 can be used as a traditional salinometer by immersing the electrode in a liquid.

The LAQUAtwin B-771 salinometer is reliable and very easy to use. It takes only a few seconds to provide a result, making it an ideal instrument for field analysis. The LAQUAtwin salinometer 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 values in many applications.

Applications:

Freshwater analysis (rain, rivers, lakes, springs), aquariums, soil analysis for enriched agriculture, and analysis of damage caused by saltwater, surface cleanliness analysis before coating, and better paint adhesion.
