Abstract
This invention relates to measurement equipment. The spectrophotometer of the invention includes a spray dispenser assembled in the case, a lighting device, a measurement unit and a control device with a set of outputs connected to a gas distribution unit and to the inputs of the supply device. The supply device is provided with an additional input connected on the additional output of the control device and the case is comprised of several elements isolated among them. The spray dispenser includes a mixing room, a burner nozzle and a diffuser. Cavities are made between internal and external surfaces of the mixing room, and fasteners are installed in the said cavities. The lighting device includes a linear spectrum radiation source, an uninterrupted spectrum radiation source and a radiation flow device having the form of optical elements and correction devices correcting the position of optical axes of the radiation source. The invention makes it possible to obtain more precise measurement results.
