The gas transmitter Dräger PIR 7000 Type 334 measures the concentration of many
hydrocarbons. It is not specific for the substances which are stored with their characteristics.
Various substance-specific sensitivities must be taken into account when specifying cross-
sensitivities.
As an example, typical values for some types of hydrocarbons are listed below.
