Digital Suction-Type Refractometer QR-NaOH
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.
