What is the freezing point of antifreeze (coolant)? How to detect?
What is the normal freezing point of antifreeze (coolant)? What's the lowest? Now the boiling point of antifreeze is generally greater than 105 deG C, if you use high-quality antifreeze, there will be no "boiling" phenomenon. But the freezing point of all kinds of antifreeze is not the same, which is decided by different regions and different environmental temperatures. 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 "engine coolant freezing point determination method" and ASTM D1177. Suitable for measuring freezing point of engine coolant and its concentrate.
Instrument features: embedded system design, using imported PT100 temperature sensor, test process automatic detection; Color touch screen; The test results can be stored; You can view historical data; The results can be printed on the instrument and automatically stirred by the machine. The experimental results can be exported through the U disk and stored in the computer for many times.
