LaserGas™ III Ultra

LaserGas™ III Ultra

It uses the innovative baseline-insensitive TDLAS technique specifically designed for combustion analysis. The Ultra simultaneously meets the requirements of combustion control and safety. That is, high measurement accuracy and high dynamic range with simultaneous real-time measurement capability.
Applications with very long path lengths and high gas concentrations are no problem for the Ultra.

Thanks to the baseline insensitivity and the use of the proprietary IROSS signal processing, high measurement accuracy is achieved even with complex gas mixtures.
LaserGas™ III Ultra CO in combination with LaserGas™ III O2 are a perfect combination for proper combustion control and safety.
