Information:

The protective gas monitor SGM7 serves the continuous measuring of the oxygen concentration in industrial, laboratory and protective gases as well as in the process of mixing and producing of special forming gases in industry. The measuring of the free oxygen concentration in inert gases and also the measuring of bound oxygen in gas compounds is possible.

The main application fields of the oxygen monitor are:

• processes for mixing and producing of forming gases;
• production processes of welding and soldering, especially gasshielded arc welding in steel and container production as well as plant construction
• production processes of electronic components under buffer gas

The introduction of explosive gas compounds, high concentrations of halogens or sulphuric gases (e.g. SO2) into the SGM7 is not permitted. The contact of the SGM7 with siliconic or phosphoric compounds is not permitted either.

The SGM7 Functions

• measures and indicates the oxygen concentration in a measuring gas continuously;
• indicates any deviations of the oxygen concentration in the measuring gas from an adjustable set value;
• monitors the course of a particular production process under buffer gas;
• checks the purity of buffer gases and determines whether the requested protective effect of the buffer gas is reached.

The requirements and limit values provided in “Technical data” must be strictly observed. Any other use is treated as non-authorized use.
