Abstract: In a device (1) for non-contact temperature measurement, it is proposed that an angle measuring device (5) is designed such that an emission angle (6) of the IR radiation detected with a detector (2) for temperature measurement can be measured on the measuring region (9) of a measuring object (3) emitting the IR radiation.

Abstract: An inspection arrangement (1) for a photovoltaic or solar-thermal solar installation, in which a thermal image of the solar installation is captured using a thermal imaging camera (2) and a measurement value of a physical measurement variable characterizing the light or solar irradiation is measured on or near the solar installation or the exposure of the solar installation by a radiation sensor (7, 8) and the thermal image and the measurement value are assigned to one another in an evaluation unit (5) of the thermal imaging camera (2).

Abstract: In a device (1) for determining the NH3 content of a gas that is being measured, a first electrochemical gas sensor (2) and a second electrochemical gas sensors (3), which are set up for detection of the content of NO and/or NO2 and/or NOx in the gas that is being measured are provided, where the gas being measured flows through the device and a converter (9) for catalytic conversion of NH3 to NOx is arranged in front of the second electrochemical gas sensor (3) in the direction of flow of the measured gas stream (4), while the first electrochemical gas sensor (2) is brought into contact with the unaltered gas (FIG. 1).
