    Measuring body for indoor measurements

    Due to the demand for more and more extensive energy-saving measures and and therefore increased insulation of rooms as well as the use of special equipment and furnishing materials, increased gaseous, particle or microbial pollution may arise in indoor air. However, the presence of hazardous substances “from the past”, such as building products containing asbestos or PCB, may also result in health risks due to indoor contaminants.

    For this reason great attention must be paid to the risks that may arise from harmful substances in indoor areas. After all, a modern life style means that many people spend the predominant portion of their lives indoors.

    The effects of indoor air contamination may manifest themselves among sensitive persons in the form of perception of unpleasant odor and taste or even neurotoxic symptoms (sick building syndrome). For health and precautionary reasons it makes sense to analyse the air with respect to its components and determine the sources. We evaluate the results of the analysis and on request offer advice on the further procedure.
