2. Use low temperature tank - low temperature thermostatic tank to add liquid medium in the front tank, the liquid level of the medium should be lower than 30mm of the table top, otherwise the heater will be damaged when the electricity is working;
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 instrument 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 use, all switches are placed in the off state, cut off the power;
7. The instrument should be cleaned regularly to keep the work surface and operation panel clean;
8. Always 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. Considering the safety factor, we stipulate that the constant temperature tank above 100 °C should be made into the 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.
Low temperature constant temperature circulator use precautions
1. The selection of liquid medium in the cryostat should meet the following principles: When the working temperature is 5 ~ 85 °C, the liquid medium is generally selected from water; when the working temperature is 85 ~ 95 °C, the liquid medium can be selected with 15% glycerin aqueous solution; When the working temperature is higher than 95 ° C, the liquid medium is generally selected oil, and the open cup flash point value of the selected oil should be higher than the working temperature of 50 ° C or more;2. Use low temperature tank - low temperature thermostatic tank to add liquid medium in the front tank, the liquid level of the medium should be lower than 30mm of the table top, otherwise the heater will be damaged when the electricity is working;
