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.
DH-10C is designed to measure specific gravity of electrolytic solution of a lead storage battery with easy operation. Taking measurements with DH-10C requires absorption of sample from the tip of nozzle and press "START" key. Right after the oparation, the temperature compensated specific gravity of dilute sulfuric acid is displayed on the screen. Display of temperature " Celsius" and specific gravity can be selected by pressing "SELECT" key.
