Description
Technical field
The present invention relates to a kind of optical match device and its optical match method, more particularly to a kind of turbidimetry optics
Optical match method with device, transmissometer, sample bottle localization method, sample bottle identification method and multiple sample bottles.
Background technology
Turbidity is the muddy degree of water, and it is that insoluble substance in water causes what the transparency of water reduced to measure.It is anti-
An index of the physical behavior of natural water and drinking water is reflected, the limpid or muddy degree to represent water is that measurement water quality is good
One of important indicator of good degree.
Current transmissometer mainly uses 7,027 two kinds of detection methods of USEPA methods 180.1 and ISO method；General principle is
On the suspended particulate that a branch of incident ray sent by light source assembly is irradiated in water, particle sends scattered light to surrounding, detection
Device is detected and the scattered light of incident light at an angle of 90.
In Optical System Design, first require by non-water sample scattering approach (such as reflection of condenser and water sample tube wall,
Scattering etc.) reach receive device veiling glare it is as few as possible, be so conducive to reduce device zero point；During measurement, not only to consider
The correctness of cleaning and the sampling of sample bottle, while should ensure that the uniformity of measurement position.
During the turbidimetry of water, the positioning of sample bottle 10 is that influence measures reappearance and the key factor of the degree of accuracy,
The method that current transmissometer is used is that sample bottle 10 is placed in measuring flume 20, makes sample with two steel balls headed on by spring 21 22
Product bottle is adjacent to reach positioning with measurement cell wall, and Fig. 1 is existing transmissometer sample bottle mounting means.
Because the scattered light intensity of turbidimetry is very faint, the cut of sample bottle surface and contamination can influence the standard of measurement
Exactness, and this localization method is easy to scratch and contaminated samples bottle；It is that glassware appearance and size is deposited additionally, due to sample bottle
In larger error, there is larger space between measuring flume, the easy run-off the straight when one side stress influences sample bottle positioning accurate
Degree.
Due to glass sample bottle material and the unevenness made influence, the direction that sample bottle is placed in measuring flume is different
When measured value differ greatly（Fig. 2）；In accurate measurement, it is necessary to which one or more sample bottles are carried out with optics pairing, current
Sample bottle pairing is that sample bottle is once rotated about 45 degree by every measurement, is carried out after 8 measurements in the one side note that measured value is minimum
Number pen makees a mark as mark, and such method needs the measurement for repeating 8 times comparatively laborious, in addition, the party
Need to rotate 45 degree of sample bottle when method is measured every time, it cannot be guaranteed that each rotation is all 45 degree in actual operating process,
The error of rotational angle is very big, so as to cause final measuring result error big, unreliable.
