Japanese Patent JP5165048
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a ground survey instrument capable of inexpensively, simply and easily measuring different measurement items.SOLUTION: A ground survey instrument comprises a sensor cable 1 having a ground measuring unit 2 on one end and a measuring instrument connected to the other end thereof. The ground measuring unit 2 comprises at least a PH measuring electrode unit 20A for measuring PH, an oxidation-reduction potential measuring electrode unit 20B for measuring oxidation-reduction potential, a resistivity measuring electrode unit (a resistivity salt measuring electrode unit 20C) for measuring resistivity, and a salinity concentration measuring electrode unit (the resistivity salt measuring electrode unit 20C) for measuring salinity concentration. The measuring instrument displays measurement values measured by the ground measuring unit 2.
