The EC2000 needs an external sampling system able to deliver an almost clean sample gas to the analyser at the proper temperature, pressure and flow rate.
ADEV has a wide experience in process and can provide the EC2000 analyser combined with a sample and condition system designed for the specific application requirements. Contact ADEV for details.
