Ozone (10028156) concentrations determined by gas detecting tubes manufactured by two companies and a microcoulomb ozone sensing instrument were compared with values obtained by a potassium-iodide (7681110) method to gain information for evaluating ozone exposures. Gas-detecting tubes are satisfactory for screening or preliminary survey work provided the tubes are calibrated in the laboratory before use in the field. The microcoulomb instrument readings agreed very well with values obtained by the potassium iodide procedure from 0 to 1 ppm (the range for which the instrument was designed).
