Description
Technical field
The present invention relates to a kind of optical match device and optical match method thereof, particularly a kind of optical match method of turbidimetry optical match device, turbidimeter, sample bottle localization method, sample bottle identification method and a plurality of sample bottles.
Background technology
Turbidity is the muddy degree of water, and it is that insoluble substance in water causes measuring that the transparency of water reduces.Being an index of the physical behavior of reflection natural water and potable water, in order to represent the limpid or muddy degree of water, is one of important indicator of weighing water quality good degree.
Turbidimeter mainly adopts USEPA method 180.1 and 7,027 two kinds of detection methods of ISO method at present; Ultimate principle is that a branch of incident ray being sent by light source assembly is irradiated on the suspended particle in water, and particle sends scattered light to surrounding, and detecting device detects and incident light scattered light at an angle of 90.
In Optical System Design, the parasitic light that first requirement is accepted device by non-water sample scattering approach (as the reflection of condenser and water sample tube wall, scattering etc.) arrival is the least possible, is conducive to like this reduce the zero point of device; During measurement, not only to consider the correctness of the clean and sampling of sample bottle, should guarantee the consistance of measuring position simultaneously.
In the turbidimetry process of water, the location of sample bottle 10 is key factors that reappearance and accuracy are measured in impact, the method that turbidimeter adopts is at present that sample bottle 10 is placed in measuring flume 20, with two steel balls that headed on by spring 21 22, make sample bottle be adjacent to reach location with measuring cell wall, Fig. 1 is existing turbidimeter sample bottle mounting means.
Because the scattered light intensity of turbidimetry is very faint, the accuracy that the cut on sample bottle surface and the meeting of contamination impact are measured, and this localization method is easy to scratch and contaminated samples bottle; In addition because sample bottle is that glassware physical dimension exists larger error, and between measuring flume, have larger space, easy run-off the straight when one side is stressed, affects sample bottle positioning precision.
Due to the unevenness impact of glass sample bottle material and making, sample bottle is placed in direction in measuring flume measured value differ greatly (Fig. 2) when different, when accurately measuring, need to carry out optics pairing to one or more sample bottles, current sample bottle pairing is that approximately 45 degree are once rotated sample bottle in every measurement, carrying out in the one side of measured value minimum, with marking pen, making a mark after measuring for 8 times serves as a mark, it is more loaded down with trivial details that such method need to repeat the measurement of 8 times, in addition, when measuring at every turn, the method need to rotate sample bottle 45 degree, in actual operating process, can not guarantee that each rotation is all 45 degree, the error of rotational angle is very large, thereby cause final measuring result error large, unreliable.
