Patent ID: 11946899
Assignee: YOKOGAWA ELECTRIC CORPORATION
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A measuring device, comprising:
a first electrode and a second electrode immersed in sample water stored in a measuring tank;
a motor that rotates the first electrode; and
a controller that operates, based on measurement results of current flowing through the sample water, in a measuring mode, wherein
in the measuring mode, the controller calculates a concentration of a measurement target in the sample water,
the motor changes a rotational velocity of the first electrode,
the controller operates in a standby mode wherein the concentration of the measurement target in the sample water is not calculated, and
when the controller operates in the standby mode, the controller controls the motor such that a first absolute value of the rotational velocity when operating in the standby mode is larger than zero and smaller than a second absolute value of the rotational velocity when operating in the measuring mode.
