*Please refer to the concentration and conductivity conversion table of Hydrofluoric Acid (HF)
(for reference only, users need to revise it on their own)
*T.C. coefficient for common solution is within 1.8~2%, but it is 0.7% for Hydrofluoric acid (HF).
Besides, according to the changes of concentration, T.C. coefficient changes and thus users need to
adjust it depending on the requirements. For example, T.C. coefficient for 0.5%, 1.0%, 3.0% HF is
about 0.70%, 0.73%, 0.74%. Users can attain the T.C. coefficient depending on actual situation of
measured solution.
