Digital Suction-Type Refractometer

Sample is drawn into the prism chamber via tube. Single-handed operation without touching any liquid is ideal for hazardous or volatile sample measurement.

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.
