Description
Technical field
The utility model relates to a kind of water quality detecting device, is specifically related to the detection to Drinking Water and pure water, belongs to the electric detective technology field.
Background technology
The barreled drinking pure water is popularized fast, enter family and office space, but the consumer can't distinguish the quality of water quality, can't know whether the water of being drunk meets relevant national standard, the conductivity measurement that quality supervision, sanitary administration superintendent office use, be professional instrument and meter, price is high, can't spread to the ordinary consumer user.I have applied for disclosing in the Chinese patent 01269151.8 a kind of pure water water quality detection device, though it can detect pure water water quality, it mainly is fixed on the water dispenser, thereby has limited its field of employment.
Summary of the invention
The purpose of this utility model provides a kind of hand-held pure water detecting device, and it is suitable for detects, measures indication intuitively accurately to multiple potable water.
The technical solution of the utility model is: this kind hand-held pure water detecting device, comprise detecting sensor and the display device that is connected in series by power supply, resistance with detecting sensor, it is characterized in that described detecting sensor, power supply, resistance and display device all are installed in the housing, detecting sensor places the housing detection head end that links to each other with housing; Described detecting sensor is the tabular or ring-shaped flat column electrode that inert metal is made, and its spacing can be 1-8mm.
The further technical scheme of the utility model is:
Described display device can adopt micro aning ammeter, LCD or light emitting diode one of any.Micro aning ammeter can adopt magneto-electric.
Described housing detection head, it can be to be flexible coupling with being connected of housing, also can be to be rigidly connected.
Principle of work of the present utility model is: with detecting sensor, promptly two of fixed-area and distance inert metal electrodes are placed in the potable water to be measured, and pure water is not owing to contain soluble ion, and its electric conductivity is very weak or non-conductive substantially; When containing the soluble ion of conduction in the water, just the same with metallic conductor, can observe Ohm law.At a certain temperature, contain the resistance R of soluble ion pure water, with spacing be that L, sectional area are that the detecting sensor electrode of A and the relational expression that contains the electricalresistivity of soluble ion pure water can be expressed as: R=ρ * L/A.And conductivity is electricalresistivity's a inverse, and unit is S/cm.Thereby in certain soluble ion concentration range, conductivity and pure water contain the linear proportional relation of concentration of soluble ion.The utility model utilizes this linear proportional relation just.
The physical and chemical index that the utility model detects can be conductivity, soluble ion concentration, also can set up mathematical model after, corresponding pH value, the total plate count index of showing.Can be with one or more directly being indicated on the micro aning ammeter dial plate in the above index.
The beneficial effects of the utility model are: both be applicable to the detection pure water, also be applicable to detection to Drinking Water water quality, have with low cost, measure indication accurately, be convenient to carry, make things convenient for ordinary consumer to use, be fit to the characteristics of large-scale commercial production.

Display device also can adopt LCD or light emitting diode etc.
Detecting sensor 2 also can adopt the ring-shaped flat column electrode, and its spacing can be 1-8mm.
Described housing detection head 6, it can be to be flexible coupling with being connected of housing 5, so that crooked, its length can determine as required that this scheme can be suitable for the detection of particular space water liquid.
Described housing detection head 6, it also can be to be rigidly connected with being connected of housing 5, and for example housing detection head 6 is connected by modes such as grafting or screw threads and detects on the container, and this kind is more suitable for fixed-site and uses.
Housing detection head 6 is connected with housing 5, no matter is flexible coupling or hard the connection, all is convenient for carrying and detects.
