Abstract
An study was carried out to evaluate the characteristics of personal sampling pumps at temperatures between 25 and minus 50 degrees-C. Low temperature had significant effects on the pumps which were evaluated. Most of the pumps provided a sampling capability which was good at minus 10 to minus 20 degrees-C. Most, however, were marginal at lower temperatures. At minus 50 degrees-C, none of the tested pumps was useful. However, the pumps did not sustain significant damage on exposure to the lower temperatures. The most suitable battery for these pumps was the nickel-cadmium battery. At low temperatures the energy produced by these batteries was reduced significantly, a large percentage of the nominal energy was available at minus 20 degrees-C and some energy was still available at minus 40 degrees-C. At minus 50 degrees-C, these batteries are not usable. The authors conclude that the personal sampling pumps evaluated were not designed for use in sub zero environments.
