- Abstract:
- A measurement system of air density that for high accuracy measurement of measuring weights is developed base on the CIPM-2007 equation. Measurements of temperature, humidity, CO2, pressure and air density are performed by this system automatically. The experimental results prove that measurement accuracy of measuring weights can be improved by using this system process air buoyancy correction.
