A conductivity meter includes a measurement unit including an electrode arranged as being in contact with sample water and a substrate on which a circuit that processes information outputted from the measurement unit is mounted. The measurement unit and the substrate are connected to each other, with a wall portion being interposed, the wall portion partitioning a space in a housing into a water section and an electric section. The measurement unit is arranged on a first surface of the wall portion on a side of the water section such that the electrode is located in an opening provided in the wall portion. The substrate is arranged on a second surface of the wall portion on a side of the electric section such that an electrode contact that electrically connects a power supply and a circuit to each other is located in the opening.

Inspection apparatus and conductivity meter

A control device controls driving of a pulse motor to cause liquid that is sucked into a syringe in a single suction process to be discharged over a plurality of discharge processes. The control method of the control device is a method that controls driving of the pulse motor so that rotation of a ball screw for executing each discharge process starts from an identical rotational angle position relative to a slit of a coupling.
