Automatic freezing point measurement of antifreeze solution
Should call the full name of antifreeze antifreeze coolant, meaning anti-freezing function of coolant, antifreeze can prevent cold season parking when coolant freezes and burst radiator and freezing engine cylinder block, but we have to correct a misunderstanding, antifreeze is not only in winter, normal maintenance project of the car, every year, need to change the engine antifreeze, Special vehicle antifreeze replacement frequency should be high.
Measure the advantages and disadvantages of antifreeze is one of the antifreeze effect, the freezing point of water is 0 deG C, the general type of antifreeze with SH128 automatic freezing point tester measuring freezing point in -25 deG C to -40 deG C, and high quality antifreeze should
It can reach about -60℃, which is an important index for calibrating antifreeze quality. Freezing point is: in no too cold
The temperature at which the coolant begins to crystallize; Or in the case of supercooling, the coolant initially crystallizes and quickly rises to the highest temperature reached.
Instrument for experiment
1, SH128 Automatic freezing point tester, using embedded system design, automatic detection of the whole process of the test; Color touch screen; The test results can be stored; You can view historical data; On the instrument
Printing results, mechanical automatic stirring, experimental results can be exported through THE U disk, stored in the computer can be compared for many times.
3, The standard is SHT0090-1991 engine coolant freezing point determination method
