Application:
KR-90B automatic engine coolant freezing point measuring instrument is designed and manufactured according to national petrochemical industry standard SH/T0090 "engine coolant freezing point measurement method", this instrument is suitable for measuring the freezing point of engine coolant and its concentrate.
Under the specified cooling conditions, when the sample to be tested is cooled to a certain temperature, after the solids are precipitated, the temperature rises again, and the highest temperature reached is the freezing point.
Features:
1. Using Chinese color touch screen operation, real-time display temperature and temperature curve of sample and cold bath;
2. Using compressor dual-machine refrigeration technology, the minimum temperature of the bath can reach -70 ° C;
3. The whole process of the test is automatically detected and automatically stored.
