HORIBA Instruments, Inc. Datasheets for Continuous Emissions Monitoring Systems (CEMS)

Continuous emissions monitoring systems (CEMS) are used for the evaluation of pollutants from a gaseous exhaust. An integrated scheme of instrument hardware and a data acquisition system allows the operator to repeatedly measure emissions to remain within environmental regulatory compliance that has been established by legislation.
