Abstract
A low-cost piezo-optical dosimeter badge has been developed for simultaneous time-weighted-average measurement of low environmental concentrations of nitrogen dioxide and ozone with low operator skill requirement. Colour reagent spots based on o-tolidine and indigocarmine, respectively, have been calibrated at 20degreesC in both gases at 50 and 70%RH, with reference to commercial chemiluminescent and UV analysers, respectively. The NO2 spots give a good calibration over 0-70 ppb, with little interference from ozone or humidity variations. The ozone spots show strong humidity effects. The origins of these effects are discussed.
