For industrial applications that require ultra-low emissions monitoring of sulfur dioxide, the SERVOPRO SO2 is the ideal solution, utilizing ultraviolet (UV) Fluorescent technology to deliver a continuous measurement you can rely on. 

The analyzer is based upon UV radiation of the sulfur dioxide molecule using light in the range of 190-230nm. The molecule absorbs the light into an excited state (SO2*) and then decays back down to the ground state, where a photomultiplier tube (PMT) converts the signal into SO2 concentration. The UV spectral region used has the least amount of interference from other gases present in the emission stream that can potentially quench the signal. 

To prevent interference and quenching from polycyclic aromatic hydrocarbons (PAHs) such as naphthalene, the SERVOPRO SO2 is fitted with a “kicker” to remove them from the sample before analysis, ensuring a reliable, accurate reading. 

Designed to slot seamlessly into a rack mounted system, the SERVOPRO SO2 is easy to integrate with existing emissions monitoring equipment. An intuitive
menu and large keypad allows for straightforward set-up and calibration. Remote operation is made possible through multiple options including RS232, and an optional TCP/IP.
