Odorant Measuring - Simple and economical

Testing the odorant content of natural gases

Natural gas is by nature odorless and for safety reasons it must be provided with an odorous substance (odorants tetrahydrothiophene or tertiary butyl-mercaptan).

In Germany the odorant content of natural gases has to be tested regularly in accordance with DVGW regulation G 280/281. The EX-TEC® OD 4 is the ideal measuring device for odorant measuring by the gas supplier.
