The application discloses a
solubility and
solid content measuring device,
system and method based on online
turbidity, the measuring device comprises a stirrer, a container for containing a to-be-measured substance and a coupled measuring device configured to simultaneously measure the
turbidity and temperature of the to-be-measured substance, the stirrer is configured to stir the to-be-measured substance, the coupled measuring device comprises a turbidimeter and a temperature
detector, the turbidimeter comprises a probe shell made of a heat-conducting material, and the temperature
detector is arranged on the inner wall of the probe shell; the stirring axis of the stirrer is configured to be arranged perpendicularly to the liquid surface of the to-be-measured substance, the turbidimeter is arranged at a certain angle with the stirrer, the probe shell of the turbidimeter is provided with a
glass window for emitting light and receiving light, and the
glass window is arranged on the probe shell away from the stirrer. The application can reduce the influence of the stirrer and external light on
turbidity determination, and improve the measurement accuracy and measurement efficiency of
solubility and
solid content.
