Background technology
Nephelometer is the device for measuring water turbidity.There are scattering type, transmitted light formula and transmitted scattered light formula etc., be referred to as optics
Formula nephelometer.Its principle is, when light is irradiated on liquid level, the mutual ratio of incident intensity, transmitted light intensity, scattered light intensity and
There are certain correlativity between water sample turbidity, by measuring transmitted light intensity, scattered light intensity and incident intensity or transmitted light intensity
The turbidity of water sample is measured with the ratio of scattered light intensity.
Its principle is that a branch of directional light is propagated in transparency liquid, if existed in liquid without any suspended particulate, then
Light beam will not change direction in straightline propagation;If have suspended particulate, light beam when running into particle will the side's of change body (no matter
Whether grain is transparent).This just forms so-called scattering light.The scattering of particle the more (turbidity is higher) light is just more serious.Turbidity is with one
Kind is referred to as turbidimetric instrument to measure.Nephelometer emits beam, and is passed through one section of sample, and from being in 90 ° with incident light
Direction on detect that how many light is scattered by the particulate matter in water.This scattering light measurement method is referred to as scattering method.It is any true
Positive turbidity must all measure in such a way.Nephelometer is not only suitable for field and tests indoor measurement, is also applied for whole day
The continuous monitoring of time.Nephelometer can be set, be allowed to send alarm, but existing colorimetric when surveyed turbidity value exceeds safety standard
Bottle when adding in sample, often filled by human hand work, it is so not only troublesome, and hold when finger is easily left on colorimetric bottle
Line just has to wiped clean before the experiments, but needs cleaning piece also relatively cleaner, otherwise will have one to measurement result
When instilling sample to colorimetric bottle manually, also there is the bad control of infusion volume in fixed influence.
