Abstract:
According to the CIPM-2007 equation, an equipment of air density measurement that for high accuracy measurement of measuring weights is developed. Measurement of temperature, humidity, pressure and CO2 are integrated on it to measure air density automatically. The experimental results prove that additional measurement of CO2 can improve accuracy of air density measurement.
