22 upper end of supporting part sets positioning area 26, and positioning area 26 helps to control the flexible disengaging side of pH test paper
To.
The depressed area 25 is less than arc convex 24, and the arc convex 24 extends to 2 edge of base, wherein arc
Test paper rest area when convex surface 24 is as detection pH value, when reagent drop coating to be measured is when on test paper, may have the part unnecessary
Reagent flows back along the body 21 of base 2, and the setting of depressed area 25 can effectively prevent unnecessary reagent and be back to test paper
In box, so as to pollute the pH test paper in paper box.
In addition, being additionally provided with colorimetric area 23 on the body 21 of base 2, the colorimetric area 23 is equipped with the pH of 14 deciles
It is worth standard colorimetric block 231, each comparator block 231 corresponds to a specific pH value from 1 to 14, after pH test paper color developments, is not required to
Moving can compare with colorimetric area 23 so as to quickly read correct pH value.
The reel tape type pH test paper includes detection layers 31 and separation layer 32, and the detection layers 31 are arranged at upper strata, uses
In detection pH value, the separation layer 32 is arranged at the bottom of detection layers 31, for preventing pH test paper osmosis pollutions base 2, shadow
Ring the accuracy of the detection of follow-up test paper.
Embodiment 1
As shown in Fig. 2, paper box is in open mode, one end of pH test paper is fixed in rotation axis 16, unnecessary pH examinations
Paper is wrapped in the form of tape measure in rotation axis 16, and can be rotated with rotation axis 16, and the other end of the pH test paper is arranged on
It is open at 15.In addition certain space is set between the lower end of pH test paper and the bottom plate 12 of paper box, pH examinations is driven in rotation axis 16
When paper rotates, it can effectively prevent the frequent friction between test paper and bottom plate 12, so as to cause to damage to pH test paper, influence pH value
Detection.When operator needs to use pH test paper detection pH value, pH test paper at opening 15 can be pulled out manually
One end, after the length for pulling needs, pulls downwards pH test paper, cutter 18 can cut off the pH examinations in thereon because of its broached-tooth design
The pH test strips removed, are then placed on 24 region of arc convex of base 2, dip test agent with glass bar, drop in by paper
Then pH test strips need not move colour developing test strips, the directly comparator block 231 with colorimetric area 23 carries out close to the position at middle part
Contrast, can fast and accurately read the pH value of institute's test agent.In addition, when the test agent that glass bar dips is more, examination
Agent can be flowed on the body 21 of base 2, and the setting of sunk area 25 can effectively prevent reagent going out by paper box accidentally
Mouth is flowed into paper box, and the test paper stored in box is polluted, and then the use detected after influencing.
Embodiment 2
As shown in figure 3, in pH test paper storages and the paper box box body 1, one end of pH test paper is fixed on rotation axis 16
On, unnecessary pH test paper is wrapped in the form of tape measure in rotation axis 16, and can be rotated with rotation axis 16, the pH test paper
The other end is arranged at opening 15.Also, the pH test paper includes double-layer structure, be respectively detection layers 31 and separation layer 32,
The wherein described detection layers 31 are used for the pH value of detection reagent, and the separation layer 32 is used to prevent the reagent of detection layers 31 from oozing
Thoroughly, wherein separation layer 32 be layer of transparent protective film, its material and property do not influence the effect of detection layers 31.When operator needs
When using pH test paper detection pH value, rocking handle 17 can be shaken, pH test paper under the action of positioning area 26 to external extension, then basis
Detection needs to cut the pH test paper of appropriate length.Obtained pH test strips are placed on the position arc convex 24 for detection
Place, wherein, separation layer 32 is below, and is fitted closely with arc convex 24, and detection layers 31 are in the top of separation layer 32, then
PH value detection is carried out to test agent, dips test agent with glass bar first, drops in pH test strips close to the position at middle part, inspection
The reagent surveyed on layer 31 is easy to permeate the pollution caused to arc convex 24, when carrying out pH value detection next time, because arc
Reagent residual on convex surface 24, pollutes pH test paper, so as to influence the accuracy of testing result.And due to the effect of separation layer 32,
The agent penetration in detection layers 31 is effectively prevent, so that having prevented pH test paper vulnerable to pollution from root influences testing result
The phenomenon of accuracy occurs.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on, should be included in the utility model
Protection domain within.
