INTRODUCTION
GasSens
is an on-line monitoring system for the detection of hazardous gases in ambient
air. It is designed to detect and alarm gas leaks from storage cylinders, process piping, or gas
feed equipment in virtually any type of industrial plant environment. Systems are available for
monitoring a variety of gases as shown in Table 1-1.
