  • Analysis instrument for determining the concentration of SO2

    The model GA25 analysis instrument is a cost-effective solution for determining the concentration of SO 2 in SF 6 gas-filled equipment. The concentration of SO 2 is an indicator for the presence of decomposition products in SF 6 gas. The advantage of the GA25 over conventional single-use test-tubes lies in the reproducibility of the measured value and the simple operation.

A need can be felt by an individual, a group, or an entire community. It can be as concrete as the need for food and water or as abstract as improved community cohesiveness. An obvious example might be the need for public transportation in a community where older adults have no means of getting around town.
