What is a salinity refractometer?
Refractometers are portable instruments for liquid concentration detection and quality control. The salinity refractometer can quickly detect salt concentration by measuring the refractive index of a solution. It is portable, accurate, and easy to use, making it widely applicable in aquaculture, fish farming, food processing, chemical industries, and other fields.
How are our refractometers different?
Handheld refractometers have been a key product of our company since 1995. We have been using solid copper for key parts like the prism base and eyepiece. This not only lends the instrument a refined, robust feel but also effectively eliminates measurement errors caused by oxidation, corrosion, or deformation, thus enhancing accuracy and durability.
In terms of optical design, we use crown glass as the prism substrate. This material is known for its low dispersion characteristics, which effectively reduce refractive deviation across different wavelengths. Additionally, each model's internal optical path is independently calculated and designed by our engineers, to maximize measurement accuracy.
