Measuring device for odorant control

Natural gas is naturally odorless and for safety reasons, odorous substances are added to it (tetrahydrothiophene). In Germany, the odorant content of natural gases must be tested at least twice a year in accordance with DVGW (German Technical and Scientific Association for Gas and Water) Code of Practice G280/281. The EX-TEC® OD 4 is the ideal measuring device for odorant measurements carried out by gas suppliers.
