ULTRA.sens

The ULTRA.sens gas measuring module specially has been developed for usage in high-quality analyzers. In the design phase, we placed particular emphasis on high stability and a low detection limit. These goals were achieved by the usage of high-performance light-emitting diodes (UV-LED) and gas discharge lamps (EDL) adapted to the needs of gas measurement technology. With this novel sensor platform we can reliably detect oxides, aromatic hydrocarbons, ketones, ozone, sulfur dioxide and halogens up to the ppb range in the spectral range from 200 nm to 400 nm.

 

 

Modulares Sensordesign

In order to adapt the measuring system to a new measurement task as flexible as possible, we have designed the individual components interchangeably. This gives us a modular kit with different components such as measuring unit, blasting unit, cuvette etc. which are interchangeable. When choosing the cuvette material, we can therefore also take advantage of all available materials such as aluminum, stainless steel glass ceramics and more. Also, it is possible to provide internal coatings in order to improve the reflective properties and increase the corrosion resistance.

Due to the decomposability, the replacement and maintenance is simpler. Since completely glued sensors have to be replaced completely, high follow-up costs (total cost of ownership) would incurre.

With this sophisticated sensor design, „exotic“ applications can be implemented without the need for a complete new development. The following figure shows a completely decomposable 5 mm sample cuvette integrated in the photometer structure instead of a 100 mm cuvette tube.
