This sensitive analyzer combines leading-edge patented sensing technologies – Paramagnetic and SBSW/Gfx Infrared – to provide unparalleled MCERTs/QAL1 measurements for reference O2, CO, CO2, NO, SO2, CH4 and N2O, (when used with a suitable sampling system).

The 4900 combines 
this monitoring power with low-cost of ownership, delivering a highly attractive analytical package. With a compact and robust design, the small footprint of the 4900 requires minimum cabinet space and can be 
easily integrated into other systems, helping to reduce installation costs.

Low operational requirements,
facilitated through long calibration intervals by ultra-stable, high performance measurement technologies and auto- calibration capabilities, make the 4900 an ideal monitoring solution with an affordability to match its impressive monitoring performance.
