This measuring instrument automatically measures gas volume / internal gas pressure, air content and oxygen concentration for quality control in the bottling process of carbonated drinks, etc.

When user set a sample container on the sample stage, all the procedures are performed automatically; punching, depressurizing, stirring of a sample, absorption of measurement gas and so on.By continuously rotating a sample container, the balance pressure of gas and sample temperature in the container are measured and calculated into gas volume / internal gas pressure, which are displayed on the LCD.

Furthermore, carbon dioxide in the sample gas is absorbed into alkaline solution to leave only nitrogen and oxygen, and then calculate air content using the residual gas volume and oxygen concentration, which are displayed on the LCD.Data printing is available by connecting an external printer to the RS-232C port and 100 measurement results can be recorded in a USB flash drive via the USB port.
