Sodium Hydroxide and Hydrochloric Acid Concentration Measurements

The measurement range of sodium hydroxide by conductivity is limited by temperature. The conductivity is limited by temperature. The conductivity of sodium hydroxide reaches a maximum value near 14% at 0º C and 29% at 100º C. Near the maximum there is poor resolution and no reliable way to know which side of the peak is being measured. Therefore, the UDA2182 measurement range is restricted by temperature to assure reliable values. Maximum concentrations are 10% at 0º C, 13% at 25º C and 20% at 75º C and above, with linear interpolation between these points. Operation above these limits gives a flashing display.

The measurement range of hydrochloric acid is restricted to less than 15.5% above 40º C and less than 18% below 40º C.
