A unique combination of NDUV and NDIR gas sensors in one module caters for a wide range of applications

The photometric gas analysis of complex gas mixtures is carried out either in the UV range (200nm-400nm) or in the IR range (2µm-12µm). Depending on which gas is to be measured, the optimum sensor technology (NDIR or NDUV) is selected.

With the KOMBI.sens, Wi.Tec has created a combined measurement option that unites both technologies. This globally unique product enables a wide range of applications in environmental and process measurement technology. In the UV range (ULTRA.sens), is the ideal option for SO2, H2S, NOx O3 and Cl2 measurements. The IR range (INFRA.sens) facilitates a variety of different gas measurements such as CO, CO2, H2O, CH4, CnHm, SF6, CF4, N2O etc. The ULTRA.sens can also measure 2 gases simultaneously, while the INFRA.sens can even measure 3 gases in one module. The KOMBI.sens is therefore ideal for a multi-gas application of up to 5 components in complex gas mixtures.

The possible measuring ranges range from a few ppm up to 100 % by volume, depending on the type of gas. Wi.Tec also offers different housing variants, which also enable optional heating (e.g. 55°C) and piping (stainless steel). Additional gas sensors are also available to measure Oxygen (O2.sens) and humidity (HUMI.sens) in combination with the KOMBI.sens module.
