Abstract
The utility model discloses a pH value test paper provided with a colorimetric card, which comprises a round fixing layer in the middle and a colorimetric card annularly arranged outside the fixing layer. The pH value test paper provided with the colorimetric card has the characteristics of reasonable design, simple structure, easiness in processing, convenience in use, safety, cleanness, accuracy in colorimetry and the like, and the experiment efficiency is improved effectively.
Description
Technical field
The utility model relates to a kind of pH test paper with colorimetric card.
Background technology
The PH test paper is that checking liquid is the instrument of acidity or alkalescence, and the experimenter uses through regular meeting when experiment.Present using method is that the experimenter takes test paper on the other hand, with suction pipe liquid is dripped on the test paper on the other hand, or test paper is dipped in the liquid, and test paper and the colorimetric card with variable color contrasts then, thereby judges the Acidity of Aikalinity of current liquid.This using method experimenter is very inconvenient, and in the use, liquid is easy to pollute experimenter's finger.
Summary of the invention
The utility model provides a kind of rational in infrastructure, easy to use, colorimetric accurately with the pH value test paper of colorimetric card.
The technical solution of the utility model is: the pH value test paper of band colorimetric card, the circular fixed bed in the middle of comprising and ring are located at the outer colorimetric card of fixed bed.
The utility model has also designed described colorimetric card and has been divided at least eight different pH value colorimetric districts.
This practical new beneficial effect is: the utlity model has reasonable in design, simple in structure, be easy to processing, clean, characteristics such as colorimetric is accurate easy to use, safe, effectively raise conventional efficient.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The pH value test paper of band colorimetric card, the circular fixed bed 1 in the middle of comprising and ring are located at the colorimetric card 2 outside the fixed bed 1.
The utility model has also designed described colorimetric card 2 and has been divided at least eight different pH value colorimetric districts.
One after another drop of color changed on the circular fixed bed pH test paper of centre with testing liquid when the utility model used, and was located at the outer colorimetric card of fixed bed with ring and compared, and drew the pH value.
Claims (2)
1. the pH value test paper of band colorimetric card is characterized in that: comprise that middle circular fixed bed (1) and ring are located at the outer colorimetric card (2) of fixed bed (1).
2. band colorimetric card pH value test paper according to claim 1, it is characterized in that: described colorimetric card (2) is divided at least eight different pH value detection zones.
