The Signal Group’s 821S Gas Divider enables the users of gas analysers to test the linearity of their instruments – simply, quickly and accurately. The 821S has ten identical capillaries and a precision balance regulator. The span gas can be selected to flow through a number of those capillaries with the diluent flowing through the remainder, to produce a ratio.
