How much is the freezing point of antifreeze (coolant) normal?
What's the lowest?
Now antifreeze boiling point is generally more than 105℃, if the use of high quality antifreeze, there will be no "boiling" phenomenon.
But the freezing point of all kinds of antifreeze is not the same, this is decided by different regions, different ambient temperature.
The freezing point of today's antifreeze is generally between -15℃ ~ -68℃.
SH/T0090 is generally used for freezing point detection of coolant.
SH128 automatic antifreeze freezing point tester is based on the national petrochemical industry standard SH/T0090-91 "Determination of Freezing point of Engine Coolant" and ASTM D1177.
Suitable for determining the freezing point of engine coolant and its concentrate.
Instrument features: embedded system design, imported PT100 temperature sensor, the whole test process automatic detection;
Color touch screen;
The test results can be stored;
You can view the historical data;
The results can be printed on the instrument and automatically stirred mechanically. The experimental results can be exported through the USB flash disk. After being stored in the computer, the experimental results can be compared for many times.
