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.
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.
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.
