apparatus for the continuous measurement of the concentration of ozone in ambient air

摘要

an apparatus is described for measuring the concentration of ozone in ambient air, pine colorimetrarea continue an absorbent solutions, sensitive ozone.absorption takes place in counterflow in a vertical column being provided with stuffing, liquid flow and constant flow through the colorimetrului continue,by maintaining a constant level in the upper tank and liquid distributor of special construction.the extinction of the spectrophotometer in the visible is converted by an electronic block directly in concentration of ozone in the air, on the basis of a calibration curve and is recorded.the apparatus can depasirii warn in case of threshold levels of concentration, predetermined.
