The product of the electronic width of the ψ(2S) meson and the branching fraction of its decay to the muon pair was measured in the e+e− → ψ(2S) → μ+μ− process using nine data sets corresponding to an integrated luminosity of about 6.5 pb−1 collected with the KEDR detector at the VEPP-4M electron– positron collider: Гee × Bμμ = 19.3 ± 0.3 ± 0.5 eV. Adding the previous KEDR results on hadronic and leptonic channels, the values of the ψ(2S) electronic width were obtained under two assumptions: either with the assumption of lepton universality Гee = 2.279 ± 0.015 ± 0.042 keV or without it, summing up hadronic and three independent leptonic channels Гee = 2.282 ± 0.015 ± 0.042 keV.
