Shanghai Haozhuang Instrument Co., Ltd. Hao Zhuang (LNB) brand low-temperature constant temperature bath is made of metal plate, and the control box is directly installed on the water tank. There are two condensate pipes in and out of the water nozzle, and the imported high-quality water pump is used as the circulating power in the water tank, which solves the disadvantages of uneven temperature water, so that the temperature control accuracy of the instrument and the uniformity of water can meet higher requirements. The low-temperature constant temperature bath product developed and produced by Shanghai Haozhuang Instrument Company can be circulated internally and externally. The two inlet and outlet pipes can be used as internal circulation by connecting the latex pipes. It can form an external circulation. A copper water pipe close to the control panel is the outlet pipe connected to the pump, and the other is the inlet pipe. Please pay attention not to make a wrong connection when connecting, so as to avoid water backflow when starting.
Points to note when using the LNB brand cryostat:
1. Add the liquid medium into the front tank of the low temperature thermostat, the liquid level of the medium should be about 30mm lower than the worktable, otherwise the heater will be damaged when energized;
2. The selection of the liquid medium in the low-temperature constant temperature bath should meet the following principles:
When the working temperature is 5 ~ 85 ℃, the liquid medium generally uses water;
When the working temperature is 85 ~ 95 ℃, the liquid medium can choose 15% glycerin aqueous solution;
When the working temperature is higher than 95 ° C, the liquid medium generally uses oil, and the open cup flash point of the selected oil should be higher than the working temperature by more than 50 ° C;
3. Power supply: 220V50Hz, the power supply should be greater than the total power of the instrument, the power supply must have a good "ground" device;
4. The instrument should be placed in a dry and ventilated place with no obstacles within 300mm around the instrument;
5. When the working temperature of the constant temperature bath is high, you should be careful not to open the upper cover and do not enter your hand with the hand to prevent burns;
6. After use, all switches are turned off to cut off the power supply;
Low-temperature constant-temperature bath instruments should do regular cleaning work 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; considering the safety factors, we stipulate that the constant temperature tank above 100 ℃ is made into an internal circulation. If the external circulation is changed according to the customer's requirements, the customer should pay special attention to the firmness of the connection of the outlet pipe to prevent it from falling off to avoid burns.
