The H2S low methanol sensor is now the standard sensor in all portable instruments that use an H2S sensor. This does not apply to COSH sensors. The H2S low methanol sensors feature a reduced cross sensitivity to methanol. Environments with background levels of alcohols or organic vapors will not affect hydrogen sulfide readings.
