Description
The Kalstein Salinity Refractometer is an essential tool for accurately testing the concentration of salt in water and brine. Specifically designed for quality control in research and clinical laboratories as well as the marine industry, this refractometer offers direct readings of specific gravity and salinity levels in parts per thousand (ppt). The dual scales allow users to easily assess NaCl levels ranging from 0-100 ppt and specific gravity from 1.000 to 1.070. Equipped with Automatic Temperature Compensation (ATC), the refractometer ensures precise measurements by automatically adjusting for temperature discrepancies, making it suitable even for marine saltwater tanks.
Market Price
Refractometers of this quality and functionality generally range between 200 USD to 280 USD in the market. It offers a competitive edge due to its durability and accuracy, ensuring a great return on investment for its price segment.
