We have performed multiprobe experiments using a Bridgman-anvil pressure cell, adapted to trap Daphne oil as pressure medium. Resistivity, ac-magnetic susceptibility, thermopower, and ac-heat capacity of a type-I superconductor, lead, have been studied at low temperature up to 5 +/- 0.1 GPa. This is the first report where ac-magnetic susceptibility has been measured in this type of pressure cell and at such a high pressure range. The signature of the superconducting transition temperature, obtained from all these different measurements, agrees well within the experimental errors.
