Refractometer is precision optical instrument that operates on the principle- as the concentration or density of a solution increases, its refractive index changes proportionately. The refractive ...

Regularly use a refractometer to check salinity levels, making sure they stay within the range of 1.020 to 1.025 specific gravity for most saltwater tanks.

Salinity among them exhibited the strongest connection and ... These were measured using handheld refractometers, pH meter, dissolved oxygen meter, and national standards of the People’s Republic of ...

Until, that is, this roughly 600,000-year-long period known as the Messinian Salinity Crisis suddenly came to an end. At first, scientists believed that the water’s return to the Mediterranean ...

Abstract: The new type of fiber optic sensor based on large offset has been widely studied. First, a double cladding fiber (DCF)-based large-offset salinity structure is theoretically proposed. By ...

Sper Scientific 300006 Salt Refractometer 0 ~ 28%. Measures salt content in sea water and pickling-brines. If calibrated for sodium chloride, it can be used for calcium chloride, barium cobalt ...
