Import 10 is poured into measurement container 7；
Step 2: clicking the detection button touched in touch display screen 1, governor circuit and power supply 5 control stirring motor 6 and carry out
Stirring stirs evenly the detected solution measured in container 7 in step 1, while making the bubble in detected solution by measurement container
Import 10 is discharged；The working method of stirring motor 6 is intermittent stirring；
Step 3: after stirring motor 6 stirs, governor circuit and power supply 5 control conductivity sensor 4, turbidity biography
Sensor 8 and temperature sensor 11 measure electrical conductivity of solution, muddy angle value and solution temperature, measure 5 times, and take solution conductivity
The median of 5 rate, muddy angle value and solution temperature measurement results；5 measurement results are successively are as follows:
1)497.2mg/L、493.6mg/L、18.1℃
2)496.4mg/L、495.7mg/L、18.5℃
3)497.5mg/L、494.9mg/L、18.5℃
4)498.4mg/L、494.5mg/L、18.4℃
5)497.4mg/L、494.6mg/L、18.4℃
Result is ranked up select 496.4mg/L, 494.6mg/L, 18.4 DEG C be final result.
Step 4: the model of tested insulator, governor circuit and power supply 5 are inputted by touching touch display screen 1 according to tested exhausted
The model XP-21 of edge determines that the external surface area of tested insulator is 1974cm2, pass through electrical conductivity of solution and muddy angle value
Median show that equivalent salt density value to be modified is 0.2514mg/cm divided by the external surface area of tested insulator2It is close with ash to be modified
Value is 0.2506mg/cm2；
Step 5: governor circuit and power supply 5 according to solution temperature median it is close to equivalent salt density to be modified and ash to be modified into
Row amendment, it is finally 0.2518mg/cm that equivalent salt density value, which can be obtained,2With the close value 0.2512mg/cm of ash2；
Step 6: clicking drain button by touching touch display screen 1, governor circuit and power supply 5 control drain motor 3 and start
Work is discharged the detected solution in container 7 is measured；
Step 7: clicking print button by touching touch display screen 1, governor circuit and power supply 5 control thermal printer 2, will
Electrical conductivity of solution, the median of muddy angle value and solution temperature, the model of tested insulator, tested insulator external surface area with
And equivalent salt density value and the close value of ash print, and convenient for record and save.
Further, the step 2 intermittent stirring is to stir each second twice, and stirring after stirring ten times terminates.
Test method through the invention learns that the equivalent salt density value of the insulator of model XP-21 is 0.2518mg/
cm2, the close value of ash is 0.2512mg/cm2；And the standard value by the way that gray density is calculated are as follows: diatomite weight is divided by insulation sublist
Area, i.e. 500mg/1974cm2=0.2533mg/cm2, the standard value of equivalent salt density value are as follows: weight sodium chloride is divided by insulation sublist
Area, i.e. 500mg/1974cm2=0.2533mg/cm2；By above-mentioned comparison it is found that the gray density that test method of the invention obtains
The error of the result and standard value of value and equivalent salt density value is respectively less than 1%.
