Selective gas analysis using infrared and ultraviolet technology


Gas composition matters

While volumetric measurement provides total gas production, gas composition reveals process quality and efficiency.

RITTER »MultiGas« Sensors use NDIR (non-dispersive infrared) and NDUV (non-dispersive ultraviolet) technology to selectively detect and quantify relevant gas components — even in complex gas mixtures.
