Description
Technical field
The utility model is related to detecting instrument field more particularly to a kind of pH value measurement devices.
Background technology
Hydrogen ionexponent refers to the ratio of the amount of hydrionic sum and total material in solution.Its numerical value is commonly called as
“pH”.Indicate the numerical value of solution acidic or degree of alkalinity, i.e., the negative value of the common logarithm of contained hydrogen ion concentration.There are many methods
To measure the pH values of solution：Use pH indicator.PH indicator is added in solution to be measured, different indicator is not according to
Same pH values can change color, and the range of pH is assured that according to the research of indicator.When titration, accurate pH can be made
Judge；
PH test paper has extensive test paper and precision test paper, is dipped on some solution to test paper to be measured with glass bar, then according to examination
The color change reference standard colorimetric card of paper can obtain the pH of solution.PH test paper can not show the pH values of oil content, because
The pH values of solution to be measured are measured with hydrogen ion for pH test paper, but do not contain hydrogen ion in oil, therefore pH test paper can not be shown
The pH values of oil content are shown；
PH meter is a kind of precision measurement equipment, and in use, pH meter is placed in casing mounted in survey for existing pH meter
It measures on material pipeline, has two seals, measure material in use, after receiving pressure effect, particulate matter enters at sealing,
When not used, it is inconvenient to rinse, in order to keep probe to keep moistening, it has been required to material measuring state is kept, for intermittent survey
Requirement is measured, is used for a long time, the pH meter service life is shortened, simultaneously because pH meter periphery is made of glass, maintenance, usually usually pH
Meter needs to calibrate, and has particulate matter at sealing ring, and when dismantling pH meter, pH meter can be damaged, and pH meter is expensive so that pH meter use at
Originally increase.
Invention content
The utility model is intended in view of the above-mentioned problems, proposing that one kind can keep probe wet always when without using pH meter
Profit, so that pH meter service life extended pH value measurement device.
The technical solution of the utility model is：
A kind of pH value measurement device, including sequentially connected pH meter, probe and test box, pH meter are equipped with display screen,
The test box side wall is equipped with feed inlet, and bottom is equipped with discharge gate, and the discharge gate is equipped with switch, and feed inlet connection is external
Feed pipe；The test upper box part is equipped with head cover, and head cover center is equipped with hole, and water absorption spongy mass is equipped in described hole, described
Probe is located at across the water absorption spongy mass in test box when detecting, and probe distal end is located in water absorption spongy mass when not detecting.
Ranging from 1/2h≤L≤2/3h of the length L of the hole, wherein h are the length of probe 3.
The feed inlet is equipped with pressure erosion control cover.
It is connected by automatic telescopic cable coiling device between the probe and pH meter.
The pH meter is equipped with lighting device.
The utility model has technical effect that：
The utility model is equipped with hole in test box upper top, and water absorption spongy mass is equipped in hole, and probe is worn when detecting
The water absorption spongy mass is crossed to be located in test box, probe distal end is located in water absorption spongy mass when not detecting, ensure probe without using
During, keep probe to moisten always, so that the pH meter service life extends.

Connect external feed pipe 8；1 top of the test box is equipped with head cover, and head cover center is equipped with hole, water-absorbing sponge is equipped in described hole
Body 4, the probe 3 are located at across the water absorption spongy mass 4 in test box 1 when detecting, and 3 front ends of popping one's head in when not detecting are located at water suction
In cavernous body 4.
Wherein, ranging from 1/2h≤L≤2/3h of the length L of the hole, wherein h are the length of probe 3 so that are visited
First 3 are not easy to fall.The feed inlet is equipped with pressure erosion control cover 6.Pass through automatic telescopic between the probe 3 and pH meter 2
Cable coiling device 5 connects, and extends the distance between probe and pH meter 2, expands use scope.The pH meter 2 is equipped with lighting device,
For under dark situation it can be seen that the pH value shown on pH meter 2.
