LaserGas™ iQ2 Vulcan

LaserGas™ iQ2 Vulcan is the first in-situ single-flange solution to measure up to four gases (O2, CO, CH4, H2O) as well as the process temperature in a single unit. 

Based on the well-proven and trusted tunable diode laser absorption spectroscopy (TDLAS) technology, the solution combines cutting-edge design and ground-breaking functionality. It is a complete combustion solution eliminating the need for multiple units. 

Advanced TDLAS technology enables unmatched reliability and durability. Installation costs of this all-in-one solution are significantly reduced since only one flange is needed. In addition, operational and maintenance costs are kept at a minimum.
