For results, immerse the probe at least 2 cm into the liquid and keep it at least 1 cm away from the container wall. Allow the display to stabilise before reading the salinity level. Construction and durability: built with materials to resist wear and tear. The pen type design is intended for longlasting use in both kitchen and professional environments, reducing the need for frequent replacements. Versatile application: suitable for a variety of salinity testing needs beyond the home kitchen. Ideal for seafood preparation, pickling vegetables, and craft cooking, enabling you to measure salt levels across different liquids with ease. Useful for both home cooks and chefs seeking to elevate flavor balance. Use scenarios: In cooking: finetune soups, sauces, and broths to achieve consistent salt levels. Pickling and brining: verify brine salinity to ensure reliable preservation and texture. Seafood and cured products: monitor salinity during brining or marination to reach desired flavor and texture.
