1. A vibrating wire viscometer housing, comprising:

  • a flowline through the housing to expose a first wire to a downhole fluid;

    a cavity in the housing to hold a magnet and to conduct one or more additional wires from the flowline to a signal generator;

    first and second electrically conductive posts mechanically coupled to the housing to hold the first wire in tension within the flowline;

    wherein the conductive posts are electrically insulated from the housing and extending from the cavity to the flowline;

    an analyzer electrically coupled to the first and second electrically conductive posts via at least the cavity to determine a viscosity based on the vibration of the electrically conductive wire; and

    a seal mechanically coupled to the housing to prevent access to the magnet by the downhole fluid.
