This refractometer is used in salt solution testing, seawater control industry and aquariums, oceans, fisheries, farms in the salt content of seawater, and low concentrations of salt in processed foods, or used to detect the specific gravity of the salt solution. Can also be used for institutions, university research and so on.
If you grow your own fruit and vegetables to produce homemade pickles or to freeze, this refractometer will give you the information that you need to ensure your end products' quality.
Vital if you need to check salt levels when preparing sea food and other ocean by-products.
Healthy fish are happy fish! Ensure the percentage of salinity in your aquarium or pond is just how your fish like it.
Essential piece of equipment used in research and clinical laboratories for checking and maintaining stock solutions and dilutions
Vital for students of Oceanography for determining the soil quality, research and clinical laboratories and marine industry
