Abstract: We report measurements of the temperature dependence of the magneticpenetration depth \lambdaT in non-centrosymmetric superconductor Re 3W. Weemployed two experimental techniques: extraction of \lambdaT from magnetic{\em dc}-susceptibility, measured on a powder sample, and the rf tunnel dioderesonator technique, where a bulk polycrystalline sample was used. The resultsof both techniques agree: the temperature dependence of the penetration depthcan be well described by weak-coupling, dirty-limit, s-wave BCS theory where weobtain $\Delta0-k BT C=1.76$. No evidence for unconventional pairingresulting from the absence of the inversion symmetry is found.
