Dosimeter Tube - Ethanol, box of 10

The passive dosimeter tube No. 112D provides the measurement of the mean value of Ethyl Alcohol in air by the principle of diffusion sampling. No air sampling equipment such as an aspiration pump or motor driven air sampler is needed for the measurement. The calibration marks printed on each tube indicate PPM x Hour & then the averaged concentration is determined by dividing the actual sampling time measured.
