Precautions for use of cryostat :
1. Use liquid medium in the front tank of the low temperature constant temperature tank . The liquid level of the medium should be lower than 30mm of the work board. Otherwise, the heater will be damaged when the power is on.
2, the choice of the liquid medium within the cryostat tank shall meet the following principles:
When the working temperature is between 5 and 85 ° C, the liquid medium is generally selected from water; when the working temperature is 85 to 95 ° C, the liquid medium can be selected from 15% glycerin aqueous solution; when the working temperature is higher than 95 ° C, the liquid medium is generally selected from oil. And the open cup flash point value of the selected oil should be higher than the working temperature of 50 ° C or more;
3. Power supply: 220V50Hz, the power supply should be greater than the total power of the instrument, and the power supply must have a good "grounding" device;
4, the low temperature thermostatic bath should be placed in a dry and ventilated place, no obstacles within 300mm around the instrument;
5. When the working temperature of the constant temperature bath is high, care should be taken not to open the upper cover, and do not enter the tank to prevent burns;
6, after using the low temperature thermostat, all switches are placed in the off state, cut off the power;
The cryostat should be cleaned regularly to keep the work surface and operation panel clean;
Always pay attention to observe the level of the liquid level in the tank. When the liquid level is too low, the liquid medium should be added in time. In consideration of safety factors, we stipulate that the constant temperature tank above 100 °C should be made into an inner circulation. If the external cycle is changed according to the customer's requirements, the customer should pay special attention to the firmness of the connection of the pipe to prevent it from falling off to avoid burns.
