Abstract
The utility model discloses a purity measuring device for an antifreeze solution. The purity measuring device comprises a test probe, an operational circuit, a conversion circuit, a power supply circuit and a display screen, wherein the test probe is connected with an input end of the operational circuit through the conversion circuit, and an output end of the operational circuit is connected with the display screen; and one path of the power supply circuit is connected with the operational circuit, and the other path of power supply circuit is connected with the conversion circuit. Compared with the prior art, the purity measuring device disclosed by the utility model has the advantages of compact structure, portability, low cost and capability of displaying the purity numerical value of the antifreeze solution through an indicating device for reading.
Description
Technical field
The utility model relates to the anti freezing solution technical field of measurement and test, particularly a kind of anti freezing solution purity determination device.
Background technology
Anti freezing solution is mainly used in that engine-cooling system is anticorrosion to solve, antiscale, anti-ly boil, the problem such as anti-cryogenic freezing.Now make the aqua type anti freezing solution of spent glycol both at home and abroad, this anti freezing solution adopts ethylene glycol to mix in different ratios from soft water more; Wherein, the higher freezing point of the content of ethylene glycol is just lower, and its freezing tolerance is also just stronger.The traditional method of test anti freezing solution freezing point is: a certain amount of sample is placed test tube, and with certain speed cooling, and measurement data temperature curve stage by stage, the flex point when curve is up to the standard is freezing point.Though this method can accurately be measured the freezing point of anti freezing solution, but need special testing equipment, skilled experimental technique and the detection time of growing, being not easy to the individual portably uses, the more impossible freezing point of when buying anti freezing solution, just measuring anti freezing solution then and there, and when field measurement anti freezing solution freezing point exactly the buyer in the urgent need to, also be the instrument that the seller need to be equipped with.
The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of anti freezing solution purity determination device simple in structure, easy to use is provided.
Its technical scheme is: comprise test probe, computing circuit, change-over circuit, power circuit and display screen.Described test probe is connected with the input end of computing circuit by change-over circuit, and the output terminal of computing circuit is connected with display screen; Described power circuit one tunnel is connected with computing circuit, and another road is connected with change-over circuit.
Wherein, described computing circuit is single chip circuit.
The utility model has compact conformation, is convenient for carrying, with low cost and can directly be read the advantage of anti freezing solution purity figure by indicating device compared with prior art.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, a kind of anti freezing solution purity determination device comprises test probe 1, computing circuit 3, change-over circuit 2, power circuit 5 and display screen 4.Described test probe 1 is connected by the input end of change-over circuit 2 with computing circuit 3, and the output terminal of computing circuit 3 is connected with display screen 4; Described power circuit 5 one tunnel is connected with computing circuit 3, and another road is connected with change-over circuit 2.Wherein, described computing circuit 3 is single chip circuit.
During use, test probe 1 is inserted in the tested anti freezing solution, power-on can be read the anti freezing solution purity figure from display screen 4.
