Abstract
The utility model provides a domestic pure water determination instrument, which is mainly composed of a resistor instrument, a container which is used for containing determination solution and a detecting head which is fixed on a container cover, wherein the detecting head is connected with the resistor instrument. The utility model has the advantages of simple structure, low cost, convenient carrying and accurate determination, and is especially suitable for families for discriminating pure water and non pure water.
Description
Technical field the utility model relates to a kind of instrument that is used to measure the pure water resistance parameter, particularly a kind of family expenses pure water analyzer.
The prior art pure water is the present main potable water of people, people prepare pure water by modes such as distillation, counter-infiltration, deionization, charcoal absorptions, need certain cost, many businessmans are for seeking exorbitant profit, just directly pretend to be pure water to sell, thereby obtain sudden huge profits with non-pure water such as tap water, rivers water.Because of this situation of mixing the genuine with the fictitious exists, people are often suspected when selecting pure water, be difficult to decide.This is that mainly whether present most of people distinguish pure water, mainly be to differentiate by naked eyes, and this discriminating is useless substantially.Though the pure water analyzer is also arranged now, existing pure water analyzer because of complex structure, cost an arm and a leg (2000-3000 unit/platform), unfavorable deficiency such as carry, make it be difficult in the common people, promote.
The goal of the invention the purpose of this utility model is to propose a kind of simple in structure, and price is low, portablely is with easy-operating family expenses pure water analyzer.
We know summary of the invention, difference pure water and non-pure water, and a main parameter index is its resistance value, pure water is few because of positive and negative ion such as solubility inorganics such as silicate, chloride, fluorides, thus resistance value is big, is generally more than the 0.5M Ω; But not pure water, more because of positive and negative ion, resistance value is then less, adds visual inspection (whether outstanding absurd creature is arranged) by the resistance value in the mensuration water and just can judge whether be pure water substantially.
Pass through following technical proposals, can realize the purpose of this utility model, a kind of family expenses pure water analyzer, it is characterized in that it by resistance instrument, a nonmetallic vessel with cover, be fixed on that a set selectable parallel resistance circuit constitutes in two detecting heads in the container cover, the circuit between resistance instrument and two detecting heads.
Be accuracy of reading, the resistance instrument can adopt digital resistance instrument.
For grasping the depth in the detecting head insertion water, nonmetallic vessel is a transparence, indicates the scale of the expression solution depth at wall.
Be provided with zeroing circuit in the circuit between resistance instrument and two probes.
Advantage of the present utility model is: 1, simple in structure: only be made of a resistance instrument and container with cover and detecting head, it can do small and exquisitely, is easy to carry.2, cheap, its cost is only about 50 yuan: selling price can be about one hundred yuan, and this price is concerning the numerous common people, and is acceptant.3, measure medium sensitivity height and accurate, this mainly is 1, has established a selectable parallel resistance circuit between resistance instrument and detecting head, when surveying pure water, can select this parallel resistance circuit, thereby can make the reading on the resistance instrument drop to low level, improve sensitivity from a high position.2, the depth controlled system in the detecting head insertion water is accurate.3, in mensuration, detecting head can not rock (situation of the hand-held detecting head of people is next rocks easily).
Below in conjunction with accompanying drawing the utility model is further set forth.
Description of drawings:
Accompanying drawing is a synoptic diagram of the present utility model
Embodiment: referring to accompanying drawing: it is digital that resistance instrument 1 can be also can be of pointer-type, and its measures scope zero Ω-1,000,000 Ω of resistance value.Lidded container 2, its material are that nonmetal, transparent, wall is marked with scale.Its effect is to hold the solution of being measured, and it is necessary for nonmetallic materials, otherwise, can influence mensuration; It is transparent, mainly in order to observe what of the solution poured in the container, thus the degree of depth that control detecting head 3 inserts in the solution.Detecting head 3 inserts dark or shallow in the solution will directly have influence on the correctness of detection data.Two detecting heads 3 are fixed on covering of container 2, and the distance between them is different and different according to the material of detecting head 3 and its diameter.Detecting head 3 is fixed on and covers, and makes mensuration not be subjected to the influence of hand-held shake; In addition,, can know and see that detecting head 3 inserts the degree of depth in the solution, thereby grasp the accuracy of measuring, avoid hand-held in the past detecting head 3 to insert not know theing depth of things in the solution and the situation that influences measurement result occurs by the scale on the chamber wall.Two detecting heads 3 electrically connect with the two poles of the earth of resistance instrument 1 respectively, in both connection circuit, also are provided with alternative parallel resistance 4 circuit and zero circuit, and they are made of with contact A, B selector switch 5.The effect of resistance 4 is to reduce the resistance reading on the resistance instrument, because the resistance of pure water is very big, reflection is very not obvious on general resistance instrument, if behind the resistance 4, then can make reading greatly reduce (can recover former reading) by conversion relation, thereby improved the sensitivity of reading, can measure the pure water of big resistance value like this with general resistance instrument.
Claims (4)
