Digital Suction-Type Refractometer QR-NaOH
Special model for Sodium hydroxide
Sodium hydroxide, also known as caustic soda or lye, is often prepared as solutions at different concentrations for a number of applications.The QR-NaOH allows the users to measure the concentrations without coming in contact with this alkali. Just plain tap water is sufficient for cleaning and zero-setting.
