Background technology
At present; at the scene for the method for bigness scale pH value; substantially be all to adopt PH test paper to test; method of testing is very simple; when test, only need workman to there is on hand pH value standard color comparison card and test paper; there are these two Key Products just can complete bigness scale; adopt in such a way, the protection of inconvenient pH value standard color comparison card, after long-time use; will more and more bad contrast colors; and in distant working-yard, in order to prevent that this phenomenon from occurring, can only be how standby; strengthened reserve level from face, too much time, the duty area of a room is also very large.
Summary of the invention
For the problems referred to above, the invention provides a kind of colorimetric clamp for the contrast of PH test paper, it is simple in structure; when use, well protecting standard colorimetric card can not damage, and has guaranteed contrast precision, uses also very convenient; do not need a large amount of standard color comparison card for subsequent use, and when contrast in, is also very convenient.
The technical scheme that the present invention takes is:
The described colorimetric clamp for the contrast of PH test paper, comprise standard color comparison card and the vertical fixed head of placing for the contrast of PH test paper, vertically offer chute in fixed head left side, in chute, be provided with the slide block can easy on and off sliding, corresponding chute is horizontally disposed with the clamping plate that are useful on folder PH test paper on the side of fixed head, clamping plate are fixed together by bolt and slide block, it is characterized in that: standard color comparison card is made up of the standard colorimetric fixture block of several different colours, standard colorimetric fixture block is equidistantly vertically arranged on the fixed head on chute right side, on fixed head, be provided with the transparent transparent panel for standard colorimetric card protection, corresponding slide block is provided with the slide mechanism sliding up and down for slide block in chute, slide mechanism comprises the screw rod being vertically arranged in chute, screw rod two ends are outer being exposed on two surfaces up and down of fixed head respectively, screw rod is arranged on fixed head by bearing, on slide block, offer the via hole passing for screw rod, on screw rod, be provided with nut with matching, nut is fixed on slide block.
For convenient observation contrasts, preferred described clamping plate right-hand member is arranged on standard color comparison card left end outside surface.
For easy for installation, preferred described transparent panel is fixed by screws on fixed head.
In order to further facilitate paired observation, on preferred described fixed head, offer the groove of placing for standard color comparison card, standard color comparison card is arranged in groove, and the outside surface of standard color comparison card is concordant with the outside surface of fixed head.
Rationally control cost for improving corresponding precision when, preferably the spacing between described adjacent standard colorimetric fixture block is 5mm～7mm.
The preferred described screw rod of the present invention upper end is provided with the knob for bolt rotary.
Compared with prior art, the beneficial effect that the present invention brings is mainly:
By the present invention, it is simple in structure, and when use, well protecting standard colorimetric card can not damage, and has guaranteed contrast precision, uses also easily, does not need a large amount of standard color comparison card for subsequent use, and also very convenient when contrast.When use, only PH test paper need be placed on clamping plate, rotation knob, under the cooperation of screw rod and nut, can be very fast complete PH contrast test, and it is higher to contrast ratio of precision, has improved serviceable life simultaneously.
