Notes:

Density Accuracy: The density accuracy is specified under normal temperature conditions, with flotation accuracy of 50cm³.
Temperature Sensor Length: If the length of the temperature sensor changes, accuracy should be re-verified. Using a uniform sensor cable, extending the length by 5m could lead to a significant temperature variance of ±2℃.
Recording Output: The recording output is configurable (standard: 0～1V).
