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.
