SERVOPRO 4200/4210



Gas analyzer suitable for flammable gas mixture

The SERVOPRO 4200 multigas analyzer is designed to monitor flammable gas samples including H2/CO, ‘HyCO’ or ‘Syngas’ mixtures for trace level contaminants and percent level components. The 4200 offers oxygen control using Servomex’s unique paramagnetic cell, trace level measurement of CO, CO2, N2O and CH4 and percent levels of CO, CO2, CH4 using photometric sensor technology.
