Technical field
The utility model relates to the measurement of visible light intensity, especially a kind of attenuated total reflection probe for middle and high concentration acid, aqueous slkali on-line monitoring.
Background technology
At present, known attenuated total reflection probe material for high concentrated acid, the dense liquid detecting of alkali and on-line monitoring adopts sapphire probe, and is not only expensive, and its order of reflection is three times, and the sensitivity of attenuated total reflection probe is not high.
The utility model content
The technical matters of the required solution of the utility model is to provide a kind of improved attenuated total reflection probe, and not only low price, highly sensitive, and can be used for middle and high concentration acid, the dense liquid detecting of alkali and on-line monitoring.
For solving the problems of the technologies described above, basic conception of the present utility model is: five reflectings surface that utilize the polyhedron appearance of attenuated total reflection probe, by five secondary reflections of light, improve the sensitivity of attenuated total reflection probe, and be applicable to middle and high concentration acid, the dense liquid detecting of alkali and on-line monitoring.
As the technical scheme that realizes the utility model basic conception, attenuated total reflection probe is cone or right cylinder, is processed with five reflectings surface on cone or right cylinder outside surface, angle 〉=140 ° between any two reflectings surface.Attenuated total reflection probe material is quartz or synthetic quartz material.
The beneficial effects of the utility model are: attenuated total reflection probe cost is low, and order of reflection is many, and is highly sensitive, and the life-span is long, is applicable to the dense liquid detecting of middle and high concentration and on-line monitoring.
