Product Portfolio

  • INFRA.sens® - Highlighted / pre-configured INFRA.sens® OEM modules

  • The INFRA.sens® was specially developed for high-quality NDIR gas analysis. In the design phase, special emphasis was placed on high stability and a low detection limit. With the use of high-performance light emitting diodes (IR-LED) and thermal micro radiators, which were adapted to the needs of gas measurement technology, these goals were achieved in full. In the spectral range from 2 μm to 12 μm, carbon dioxide, carbon monoxide, hydrocarbons and nitrous oxide can be reliably detected up to the ppm range with this new sensor platform.

          • NDUV sensor technology now ready for corrosive gases

            In many areas of process engineering, reactive gases are used as starting products in chemical processes. These gases often are corrosive, so that only certain materials can be used. In process measurement technology, these gases are usually detected with special photometers that are located locally outside the process. The process gas therefore comes in contact with all materials on its way from the process to the sample cell. Both the design of the gas paths and that of the sample cell must therefore be adapted to these requirements.

                        • BINOS NG

                        • Gas analysis using the method of selective radiation absorption in the UV and IR range (NDUV / NDIR) is an established method for determining concentrations in complex gas mixtures. The BINOS NG Gas Analyser uses state-of-the-art optical components to achieve optimum analysis results. This leads to high-resolution gas analyses that can reliably detect concentration changes in the ppb range. Wi.Tec has rediscovered the BINOS and is building on the philosophy of this successful generation of appliances. Up to two OEM modules can therefore be installed in the following combinations:

                          • 1x INFRA.sens® + 1x ULTRA.sens®
                          • 2x INFRA.sens®
                          • 2x ULTRA.sens®

                          Up to 3 physical measuring channels can be implemented per module, so that a total of 6 gases or measuring ranges can be recorded and analysed simultaneously in the Binos NG.

                          The BINOS NG can be equipped with customised filters and extraction pumps.
