Description

The Kalstein Salinity Refractometer is a precision optical instrument designed to measure the salt concentration in saltwater or brine, commonly utilized in quality control within research and clinical laboratories, as well as in the marine industry. It features two scales: one for measuring NaCl levels within a range of 0-100 parts per thousand (ppt) and another for determining specific gravity between 1.000 and 1.070. Equipped with Automatic Temperature Compensation (ATC), this refractometer adjusts to temperature changes, ensuring accurate results regardless of environmental conditions. With a durable, high-quality construction and an ergonomic non-slip rubber grip, it is ideal for use in marine aquarium maintenance and scientific applications.
