Technical field

The utility model relates to the technical field of experimental equipment, and in particular to a constant temperature bath control device.

Background technique

During the operation of the constant temperature bath equipment, a large amount of constant temperature bath medium is often lost due to evaporation or carrying of objects. In order to ensure the smooth operation of the constant temperature bath, the constant temperature bath medium needs to be replenished in time. During the replenishment process of the constant temperature bath medium, artificial naked eye judgment is usually relied on.
