About electric conductivity : Potassium chloride standard solution
The electric conductivity cell changes its cell constant during long-term use due to the accumulation of dirt and the loss of platinum black.
Therefore, it is necessary to periodically measure and test the cell constant with potassium chloride standard solution.
We offer two types of electrical conductivity cell check liquids as shown below.
Check liquid for EC cell 0.01mol/kg 100mL (4 bottles) 140.8mS/m at 25℃
(Code number: 143A144)
Check liquid for EC cell 0.1mol/kg 250mL (2 bottles) 1282mS/m at 25℃
(Code number: 143A143)
