Answer: a Brinometer! Brine is simply defined as a solution of salt in water. It has a wide variety of uses from the transport of thermal energy, de-icing the roads or in cooking to preserve meat or vegetables. The low levels of salinity commonly found in food or seawater can be tested in a number of ways such as on the Laqua Twin sodium meter , Laqua Twin salt meter or for a multi-pa...
Sodium is a mineral required by the body for normal functions, but excessive intake can cause high blood pressure and hypertension. This has lead governments and regulatory bodies to focus on monitoring the levels of salt in foods in order to reduce the risk of these health affects. Canned foods are of particular concern as these often contain relatively high levels of salt. The Horiba La...
Seawater has an average salinity of 35 ppt = 35 parts per thousand (equivalent to 35,000ppm or 3.5%). However the salt level does change depending on rainfall, evaporation, ice thawing or rivers, so the salinity can vary over areas, time or seasons. Camlab can offer two handheld meters which quickly and directly measure salinity up to the high levels required for seawater. [caption id=...
A hydrometer is an instrument that is made of glass and consists of a cylindrical stem and a bulb weighted with mercury or lead to make it float upright. It is used to measure the Specific Gravity (SG) of liquids. In other words the ratio of density of the liquid to the density of water.The SG of water is 1.000 at 4°C. For example the lower the density of a substance the farther the h...
