Target Gas Specifications
This Brasch Gas Transmitter is available for monitoring carbon monoxide and/or nitrogen
dioxide as target gases. Regulatory agencies have determined the threshold concentrations at
which the gases become dangerous. Brasch Environmental Technologies, LLC has designed
their transmitters so that the measurement ranges for each target gas meet the agencies’
requirements. Each target gas, for which Brasch currently produces a transmitter, is listed
below along with the relevant concentration specifications.
