Sample is drawn into the prism chamber via tube. Single-handed operation without touching any liquid is ideal for hazardous or volatile sample measurement.
Squeeze the pump to create a vacuum and then release to draw the liquid in. Cleaning is as simple as operating the pump a few times in water. The prism chamber can also be opened up for removal of persistent residues.
Digital Suction-Type Refractometer QR-Brix
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.
Digital Suction-Type Refractometer QR-NaOH
This model is specifically designed for measuring sulfuric acid, which makes it ideal for a wide-range of applications in the industrial or pharmaceutical industries.The QR-HSO allows users to easily measure the concentration of sulfuric acid without coming in contact with this highly corrosive acid.Cleaning and zero-setting can be done with tap water.
