The invention discloses a conductivity-type online pulp concentration meter and a measuring device having the same, which belong to the technical field of pulp concentration/density measurement. The conductivity-type online pulp concentration meter comprises at least two insulated connecting pipes and at least three electrode pipes, wherein the insulated connecting pipes and the electrode pipes are arranged at intervals; the insulated connecting pipe is arranged between adjacent two electrode pipes; two adjacent electrode pipes are connected with two end parts of the insulated connecting pipe;the electrode pipe comprises a liquid contact ring section; and in the case of measurement, only the liquid contact ring section in the entire electrode pipe is contacted with the pulp. When the conductivity-type online pulp concentration meter is applied to pulp concentration measurement, online measurement on the pulp concentration can be carried out more conveniently, poor connection or wastedpower transmission between the process sections can be avoided, and the use needs of mines for the online concentration/density meter can be met.
