Abstract
A measuring device includes: a first electrode immersed in sample water stored in a measuring tank; a second electrode immersed in the sample water; and a controller that: causes a power source to flow a current through the sample water between the first electrode and the second electrode; detects, based on a first digital signal, an interruption whereby an analog signal fluctuates by no less than a predetermined value; and calculates, based on a second digital signal, a concentration of a measurement target in the sample water. The first digital signal is acquired by sampling the analog signal with a first sampling period. The analog signal is based on the current flowing through the sample water. The second digital signal is acquired by sampling the analog signal with a second sampling period that is longer than the first sampling period.
