We have measured the transverse dielectric constant of KH2PO4 crystal from liquid N2 to room temperatures. Extending the Blinc-de Gennes' model in conjunction with a cluster approximation leads to a new independent determination of the Slater-Takagi parameters and improves significantly the fit of the model to the data.
