PONPE 591DO เครื่องวัดและควบคุมค่าออกซิเจนในน้ำ Dissolved Oxygen meter Controller

 Features

• Applications: PONPE 591DO Dissolved oxygen is the measure of oxygen dissolved in an aqueous solution. 
• Polarographic measurement principle, the dissolution value depends on the temperature of the aqueous solution, pressure and salinity in solution. 
• The meter uses a liquid crystal display for measuring and displaying DO and medium temperature values, with analog and digital signal outputs and control functions.
