Precautions for the use of cryogenic baths

Low temperature and constant temperature water tanks are widely used in petroleum, chemical, electronic instrumentation, physics, chemistry, bioengineering, medicine and health, life science, light industry food, physical property testing and chemical analysis research departments, colleges and universities, enterprise quality inspection and production departments, Provide a field source with controlled heating and cooling, uniform and constant temperature for users to perform constant temperature tests or tests on test samples or produced products, and can also be used as a heat source or cold source for direct heating or cooling and auxiliary heating or coolin.
Precautions for useAdd liquid medium to the front tank of the low temperature constant temperature tank, and the liquid level of the medium should be about 30mm lower than the worktable, otherwise the heater will be damaged when it is powered on;The selection of liquid medium in the low temperature constant temperature tank should meet the following requirements Principle: When the working temperature is 5～85℃, the liquid medium is generally water; When the working temperature is 85～95℃, the liquid medium can be 15% glycerin aqueous solution; When the working temperature is higher than 95℃, the liquid medium is generally selectedPower supply: 220V AC 50Hz, the power supply power should be greater than the total power of the instrument, and the power supply has a good "grounding" device;The instrument should be placed in a dry and ventilated place, and there are no obstacles within 300mm around the instrument;When the working temperature of the thermostatic bath is high, be careful not to open the upper cover and keep your hands away from the bath;After use, turn off all switches state, cut off the power;
