Cross SensitivityOther chlorinated hydrocarbons are indicated
as well but with different sensitivities. It is not
possible to measure epichlorohydrin in the
presence of free halogens and hydrogen
halides in the TLV range because they are
indicated as well. Petroleum hydrocarbons
cause low readings.
