Molar conductivities of aqueous electrolytes at 1 M

In the following table from the CRC Handbook, molar conductivities of aqueous electrolytes are given for concentrations from infinite dilution to 0.1 M. However, I am looking for values at 1 M, and I’m having a hard time finding that information. (The following table probably stops at 0.1 M because the Debye-Huckel-Onsager equation is only accurate for very dilute solutions.)

This is a soft question, I admit, but can anyone suggest resources for finding tables of molar conductivities of aqueous electrolytes (i.e., typical ones like $KCl$, $KOH$, $H_2SO_4$) at 1 M?
