1. The instrument should be placed in a dry and ventilated place with no obstacles within 300mm around the instrument;
2. The liquid medium is added into the front tank of the low temperature constant temperature tank. The liquid level of the medium should be lower than the working plate by about 30mm, otherwise the heater will be damaged when the electricity is turned on;
3. 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;
4. The selection of liquid medium in the cryostat should 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 ~ 95 ° C, the liquid medium can be selected with 15% glycerol 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;
Note: The working temperature here refers to the temperature to be reached by the liquid medium in the tank;
5, power: 220V50Hz, the power supply should be greater than the total power of the instrument, the power supply must have a good "grounding" device;
6. After use, all switches are turned off and the power is cut off; the instrument should be cleaned regularly to keep the work surface and operation panel clean; always pay attention to observe the liquid level in the tank. When the liquid level is too low, Add liquid medium in time;
In view of safety factors, we have specified an internal circulation of a thermostatic bath above 100 °C. 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.
