Description
Technical field
The utility model relates to a kind of anti freezing solution freezing tolerance and surveys device, the particularly a kind of portable anti freezing solution freezing tolerance proving installation that can directly read the anti freezing solution freezing point temperature.
Background technology
Anti freezing solution is mainly used in that engine-cooling system is anticorrosion to solve, antiscale, anti-ly boil, 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 with soft water more; Wherein, the high more freezing point of glycol content is just low more, and its freezing tolerance is also just strong more.The traditional method of test anti freezing solution freezing point is: quantity 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 testing equipment that need be special, skilled experimental technique and long detection time, 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 press for, also be the instrument that sale person need be equipped with.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of portable anti freezing solution freezing tolerance proving installation simple in structure, easy to use is provided.
Its technical scheme is: comprise test container and test electronic circuits.Described test container is made up of housing, sensor, probe and cold-making block, and described cold-making block is installed in housing bottom, and sensor and probe are installed in the housing both sides respectively; Described test electronic circuits comprises computing circuit, change-over circuit, buffer circuit, driving circuit, power circuit and display screen, computing circuit is connected with change-over circuit, buffer circuit and driving circuit respectively, power circuit one tunnel is connected with computing circuit, another road is connected with driving circuit, and computing circuit also is connected with display screen; Sensor in the described test container is electrically connected with change-over circuit in the test electronic circuits, and probe is electrically connected with buffer circuit, and cold-making block is electrically connected with driving circuit.
Wherein, the housing of described test container is circle or rectangular configuration.Described sensor is a temperature sensor.Computing circuit is a single chip circuit.
The utility model has compact conformation, is convenient for carrying, the with low cost and advantage that can directly be read anti freezing solution freezing point numerical value by indicating device compared with prior art.
