Product Overview

The Underground Gas Content All-in-One Measuring Instrument is an intelligent testing device developed based on the gas expansion displacement principle, utilizing a computer control system to achieve fully automated detection processes. It is suitable for measuring the true density, volume, and porosity of various solid materials (powdered/granular/lumpy/foamed), slurry substances, and non-volatile liquids.
