Abstract: The photometer is calibrated by using a permanently built-in installation of four, similarly configured chambers in a good heat conducting carrier which is slidably interposed between sample and reference chambers on one hand and the detection structure on the other hand. One pair of these chambers is placed in the paths during measurement and is filled with inert gas, the other pair has one chamber filled with calibration gas, the other one with inert gas. All chambers are closed with similar windows.

Abstract: A spectroanalytical gas measuring apparatus has a radiation source (36), a transmitting condensor (19), an objective (13) and a beam divider (11) which deflects at least a part of the radiation reflected back to the apparatus by a reflector (40) to a polychromator or spectrometer (32). The transmitted radiation falls after the beam divider (11) onto a deflecting mirror (12) which is adjustable between two positions and which directs the light to an objective reflector (13). The objective reflector (13) reflects the radiation to a follow-up mirror (15) arranged opposite to the beam passage opening (14). At least one long and one short focal length objective reflector (13) are provided in order to ensure different ranges of distance in conjunction with the adjustable deflecting mirror (12).

Abstract: A non-dispersive infrared gas analyzer especially adapted for measuring the concentrations of HC, CO and CO.sub.2 in a vehicle exhaust includes a sample chamber for holding a sample gas, a radiation emitter for directing a beam through the chamber and a detector for indicating the amount of radiation absorbed. A plurality of filters each of which transmit radiation at an absorption band of a gas component to be detected are alternatingly positioned in the radiation path to produce a time-multiplexed signal having concentration information for all gases. The time-multiplexed detector output is corrected for gain and offset errors "on-the-fly", without requiring demultiplexing, through the use of an analog multiplier circuit. The correction factors are themselves determined without demultiplexing the detector output signal.

Abstract: A measuring instrument for simultaneous in situ determination of the spectral scatting and absorption coefficient, which can also be called an extinction meter, has a modulated light source and an optical system encompassing the hemisphere; the optical system has a multiply folded ray path with a focal point in the volume to be measured, and through this system the measurement signal is projected to detectors. The scattering measurement signals, which are maximally enlarged in this way, are then separated from those for the absorption. The extinction meter also has not only an integrating nephelometer for monitoring purposes but also a transmission meter for low transmission factors. Because of the small three-dimensional size and the streamlined shape of the measuring portion of the extinction meter, the extinction meter can be carried in aircraft and surface vehicles. Because of the disposition of the optical system, the error in the measurement values is negligible, in comparison with other instruments with which only the scattering coefficient can be determined. Moreover, the calibration value during a measurement phase can be determined both automatically and manually. Contamination of the instrument with gas to be measured is reduced, by the stabilization of a turbulence ring by means of baffles. Moreover, interference with the flowing aerosol on the part of the instrument is largely eliminated via a hoop-like hood functioning like a wing-tip slot.
