BetaCAP30 is a gas divider that uses 30 capillaries, to operate 31 dilution ratios (between 0 and 100% of the concentration to be diluted). The choice of 30 capillaries is not aimed at carrying out tests on 30 steps, but to increase the diluter application flexibility reducing the number of required cylinder concentrations. With BetaCAP30 it is possible to perform linearity tests on 5 steps (0, 20%, 40%, 60%, 80%, 100% of the measurement range) using cylinders that contain up to 6 times the analyzer’s span concentration.
