Abstract
The utility model discloses a kind of detecting systems for the measurement of aqueous surfactant solution pH value, including magnetic stirring apparatus, beaker and electronics pH meter, beaker is placed in the work disk of magnetic stirring apparatus, the magnetic agitation pearl of magnetic stirring apparatus is placed in beaker, and in the detecting electrode insertion beaker of electronics pH meter and detecting electrode head is set close to beaker bottom.This changes original detection method for the detecting system of aqueous surfactant solution pH value measurement, and detection efficiency is high.
Description
Technical field：
It is especially a kind of to be measured for aqueous surfactant solution pH value the utility model is related to a kind of measuring device
Detecting system.
Background technology：
In the prior art, the measure (potentiometry) of aqueous surfactant solution pH value, will prepare the measurement of pH
Solution is poured into beaker, is placed on magnetic stirring apparatus and is stirred 30s, is stopped stirring, is then put on pH and is detected, treat that pH meter is steady
After determining 1min, reading.Then beaker is put back on magnetic stirring apparatus again and be stirred, beaker taken surveyed on pH meter again
Amount, same sample need to measure 2 times or more, it is desirable that the difference of measurement is not more than 0.1pH units.
But found in actual measurement, the electrode of p meters stablizes reading after 1min, stirs the solution for the second time, pH values have compared with
It significantly fluctuates, the difference of measurement is larger twice, needs duplicate measurements 3 times or 4 times at this time, and even more repeatedly, it is accurate to cause
Degree is not high, and measure elapsed time is more, greatly reduces real work efficiency
Utility model content：
Technical problem to be solved in the utility model is to provide a kind of facilitate and detects aqueous surfactant solution pH value
For the detecting system of aqueous surfactant solution pH value measurement.
The technical solution of the utility model is to provide a kind of detection for the measurement of aqueous surfactant solution pH value
System is placed in including magnetic stirring apparatus, beaker and electronics pH meter, beaker in the work disk of magnetic stirring apparatus, magnetic stirring apparatus
Magnetic agitation pearl be placed in beaker, in the detecting electrode of electronics pH meter insertion beaker and detecting electrode head is close to beaker bottom
It sets.
Using compared with prior art, the utility model has the following advantages after more than structure：By the detection of electronics pH meter
Electrode is put into beaker, and beaker is stirred as the aqueous surfactant solution side on magnetic stirring apparatus, so achieved that in beaker
Frontier inspection survey is mixed, twice, the difference of measurement will not generally be not more than 0.1 pH units, improve accuracy in detection for same solution measurement,
The time is saved simultaneously, reduces detection number, improves detection efficiency.
Preferably, the detecting electrode is vertically arranged in beaker.Improve accuracy of detection.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment：
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Figure 1, it is a kind of for aqueous surfactant solution pH value measurement detecting system, including magnetic stirring apparatus 1,
Beaker 2 and electronics pH meter 3, beaker 2 are placed in the work disk 4 of magnetic stirring apparatus, and the magnetic agitation pearl 5 of magnetic stirring apparatus is placed in
In beaker 2, the detecting electrode 6 of electronics pH meter 3 is inserted into beaker and 6 head of detecting electrode is set close to 2 bottom of beaker, and examines
Electrode 6 is surveyed to be vertically arranged in beaker by the fixing bracket of electronics pH.
During detection, electronics pH meter and magnetic stirring apparatus are separately energized, surface to be detected is then poured into beaker and is lived
Property agent aqueous solution, the volume poured into accounts for the 1/2 of beaker, opens magnetic stirring apparatus and be stirred.Treat electronics pH meter stable testing
After being present with √ A on the display screen of electronics pH meter afterwards, you can read pH value, twice, the difference of measurement is not more than for same solution measurement
0.1pH units.The pH value as measured.The detecting system generally only needs measurement twice, you can determines numerical value, improves detection
Efficiency.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.Every equivalent structure or equivalent flow shift done using the utility model specification and accompanying drawing content is included in this
Within the scope of patent protection of utility model.
