BetaCAP60X100 a compact diluter with 3 inputs (two gases to be diluted in a diluting gas), pre-dilution just for an input and flow comparator for self-checking with relative deviations calculation. BetaCAP60X100 is built complying with the principles that inspire the entire Be.T.A. production : equal capillaries, electronic pressures control and manifold construction in highly corrosion-resistant materials. Very similar to the BetaCAP60-3G model, is distinguished only by the addition of a module pre-divider by 100, inserted in series at the TG1 gas inlet (measurand).
