Emissions industrial analyzer, SEITRON, CHEMIST 900 RACK

The Chemist 900 Rack is our new industrial emissions analyzer. This device can measure emissions generated by industrial combustion or transformation processes and it analyzes different gases thanks to the NDIR and electrochemical technology. The distinctive feature of the Chemist 900 Rack is its rack structure that allows to use it into standard 19’’ cabinet or even in laboratories because it comes standard equipped with 4 rubber bumpers. The Chemist 900 Rack is designed to perform long-lasting analyses periods thanks to an automatic commutation system that allows to reset both the gas sensors and the pressure sensor used for draft measures or differential pressure measures. This, together with a Pitot tube, allows measure the smoke speed inside the evacuation duct.
