    The GSV-1 Post with a Combined Annunciator is designed for continuous measurement of concentration, for example, methane gas in the air of the working area with the possibility of providing light and sound alarms at two thresholds, e.g. 20% LEL and 50% LEL.

    The Post can be supplied with any of Gas Analyzer from the GSV-1 series.

    The Gas Analyzer can be supplied with digital or analogue output.
