Abstract
Filtering and absorbing products in the form of a plate and working under conditions of convective blowing with cleared air residual life indicator uncertainties of measurement analysis is carried out. It is shown that for 0.8 mm thick KO2-based sorbent plates at a relative humidity of 60…90 % and a CO2 concentration of 1…4 %, the main factor of the uncertainty of indirect measurement of the residual life indicator is the Biot parameter characterizing the conditions of heat transfer from the plate surface. It has been experimentally proven that for Biot parameter in the range of 0–0.08, this factor contributes up to 30 % in the total uncertainty.
