The conductivity of KH 2 PO 4 (KDP) aqueous solutions with varying saturation temperature from 28.5°C to 41.8°C was measured in the temperature range of 30°C to 40°C. It's proposed that the conductivity of KDP solutions can be expressed by L=L o +b 1 T+b 2 T 2 . This relation can be interpreted by Falkenhagen's (1971) conductivity model of high concentration electrolyte solution. The experimental data agrees well to the relation with an accuracy of super‐saturation within ±0.03g KDP/100g water (±0.10% relative super‐saturation).
