Abstract
The invention relates to ozone density analyzing instrument. It adopts micro ultraviolet lamp tube, uses ultraviolet ray intensity difference between the close range receptor and the path opening one to calculate out the ozone density. Thus it can economically, conveniently, and fast gain the density reading, widely be used in industrial detecting.
Description
Technical field
The present invention relates to a kind of gas analysis instrument, especially the ozone concentration analytical instrument.
Background technology
The principle of present sterilization portable field ozonograph is based on the airborne ozone of sample fades the sodium indigotindisulfonate in the absorption liquid, generates the isatin sodium disulfonate.The degree colorimetric analysis that selective absorption is set up to visible light that weakens according to color.Instrument is made of silicon radiant, colorimetric bottle, integrated electro sensor and microprocessor, can directly demonstrate the content of ozone in the sample on liquid crystal display.Also having a kind of is the film-type semiconductor-type.
These two kinds all exist device fabrication cost and the high problem of use cost, can not popularize the commercial market; Equipment needs preheating etc. simultaneously, uses loaded down with trivial details inconvenience, inefficiency.
Summary of the invention
Task of the present invention provides a kind of easy to use, economy, ozone concentration analytical instrument that efficient is high.
The present invention adopts the micro type ultra-violet fluorescent tube, calculates the analytical instrument of ozone concentration by the uitraviolet intensity difference between the receptacle of closely receptacle and open approach.Because ultraviolet ray will decay through the air that contains ozone, can just can draw ozone concentration by calculating attenuation ratio like this.
Owing to adopt ultraviolet decremeter algorithm, just can obtain concentration readings economical, quickly and easily.
Embodiment
In concrete the enforcement, because the ceiling value of the industrial hygiene standard most countries of ozone is 0.1ppm (0.20mg/m
3), so the instrument design sensing range can be between 0.01～1ppm (service range show can arrive 5ppm), and indicate corresponding reading safe class.
Simultaneously, for reducing the instrument volume, open space can be used the distance that repeatedly comes and goes the path reduced volume of refraction and increase ultraviolet process, high-level efficiency ultraviolet reflectance instrument should be provided during application, the refraction loss rate should be deducted during calculating, just concentration accurately can be drawn.
In addition, contrast differences can draw reliable readings by the electronic circuit amplification.
Claims (3)
1. an ozone concentration analytical instrument is characterized in that adopting the micro type ultra-violet fluorescent tube, calculates the analytical instrument of ozone concentration by the uitraviolet intensity difference between the receptacle of closely receptacle and open approach.
2. according to claim 1, it is characterized in that adopting the instrument design sensing range can be between 0.01～1ppm (service range show to arrive 5ppm), and indicate corresponding reading safe class.
3. according to claim 1, it is characterized in that adopting the path that the open space use is is repeatedly come and gone refraction.
