Description
Technical Field
The invention relates to a test method, in particular to a TruRead turbidity measurement method.
Background
During the test of actual water sample turbidity, the higher water sample of turbidity is even and the judgement of settling time after the sediment brings the operation error of operator's subjectivity very easily. Some manufacturers have also adopted multiple measurements to reduce this error. But they all showed only the average results of multiple tests after testing. This approach may reduce the error of the test, but does not help the user to determine whether the solution being tested is stable, and still results in inaccurate testing
However, in the case of actually measuring water with large and many particles (such as high turbidity water like river water, sea water, industrial water, sewage, etc.), the settling rate of large particle solids is high, the turbidity in the solution is not uniform, and the reading value of the large particle solids is greatly wrong along with the measurement time when the large particle solids are measured by a common method.

The invention is realized by the following technical scheme: a TruRead turbidity measuring method comprises the following specific steps:
selecting at least two turbidity meters, and setting the repeated measurement times by a measurer according to the requirements of a user;
after the measurement is finished, the instrument displays all the measured values, automatically calculates the average value, the maximum value and the minimum value of the measured values, and can automatically store all the measured data according to the requirements of users;
the average value is used for more accurately reflecting the turbidity value of the solution, the turbidity is large, more measurement times can be adopted when solid particles are large, and less measurement times can be adopted when the turbidity is small, so that the working efficiency is improved;
(IV) the difference between the maximum value and the minimum value obtained by measurement is used for reflecting the property of the solution: a large difference indicates a large turbidity and coarse particles of impurities, and a small difference between the maximum and minimum indicates a large but relatively uniform turbidity.
As a preferred technical scheme, the at least two kinds of nephelometers are TN-100 and TN-500, and the TN-100 and TN-500 are both provided with a 'TruRead' mode which is used for observing the process from turbidity change to stability and can also be used for precipitating a faster sample solution.
As a preferred technical scheme, a 'TruRead' mode of continuously measuring 5 times is adopted for a common water sample, and a 'TruRead' mode of 10 times, 15 times and 20 times can be selected for a solution which rapidly settles or continuously changes.
As a preferred technical scheme, at least two kinds of turbidity meters are provided with a display module and a storage module, all measured values are stored through the storage module, and a test result is displayed through the display module.
The invention has the beneficial effects that: the method can improve the repeatability and accuracy of turbidity measurement, reduce the workload of users and provide convenience for the users to accurately measure the turbidity value of the solution; while measuring turbidity, the solution condition can be analyzed from the measured value.

The specific method of the TruRead turbidity measurement method comprises the following steps:
selecting at least two turbidity meters, and setting the repeated measurement times by a measurer according to the requirements of a user; after the measurement is finished, the instrument displays all the measured values, automatically calculates the average value, the maximum value and the minimum value of the measured values, and can automatically store all the measured data according to the requirements of users; the average value is used for more accurately reflecting the turbidity value of the solution, the turbidity is large, more measurement times can be adopted when solid particles are large, and less measurement times can be adopted when the turbidity is small, so that the working efficiency is improved; (IV) the difference between the maximum value and the minimum value obtained by measurement is used for reflecting the property of the solution: a large difference indicates a large turbidity and coarse particles of impurities, and a small difference between the maximum and minimum indicates a large but relatively uniform turbidity.
In the embodiment, the at least two kinds of nephelometers are TN-100 and TN-500, and both TN-100 and TN-500 have a 'TruRead' mode which is used for observing the process of changing turbidity to be stable, and can also be used for precipitating a faster sample solution.
The turbidity meters comprise a display module and a storage module, all measured values are stored through the storage module, and test results are displayed through the display module.
As shown in fig. 1, the first row in fig. 1 is the average value and the second row is the maximum value and the minimum value. This is followed by 10 test data and these interfaces can all be stored in memory.
As shown in fig. 2, the first row in fig. 2 is the mean and the second row is the maximum and minimum, followed by 20 test data, which can all be stored in memory.

As shown in fig. 4, fig. 4 is a graph showing turbidity measurements using various water qualities of "TruRead".
The conventional mode test used for the turbidity measurement of a complex water sample obviously has larger error, and for this reason, a 'TruRead' mode of continuously measuring for 5 times is adopted for a common water sample. For solutions that settle rapidly or change continuously, the "TruRead" mode can be selected 10 times, 15 times and 20 times to ensure accuracy of the test. The "TruRead" mode is used to observe the turbidity change to a stable process, and can also be used to precipitate faster sample solutions.
The invention can select the number of times of measurement (5-20) by a user according to the property of the tested water sample during the test, and then the instrument displays the value (5-20 times) and the maximum value, the minimum value and the average value each time during the test. The mode can help a user to judge whether the tested water sample is stable in sedimentation, so that a correct test result is obtained.
