Target Gas Specifications
Remote transmitters for this control panel are 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.
