Precautions for use: 1. Power supply: 220V AC 50Hz, the power supply should be greater than the total power of the instrument, the power supply must have a good "grounding" device; 2. Use the liquid medium in the front slot of the cryostat, the medium level should be lower than the working The platen is about 30mm, otherwise the heater will be damaged when the power is on. 3. The selection of the liquid medium in the cryostat should meet the following principles: When the working temperature is 5~85°C, the liquid medium is generally water; when the working temperature is 85 When the temperature is ~95 °C, 15% glycerin aqueous solution can be used for the liquid medium; when the working temperature is higher than 95 °C, the liquid medium is generally selected with oil, and the open cup flash point value of the selected oil should be higher than the working temperature by 50 °C or more; Shanghai Xinzhuang has an industry-recognized team of experts and first-class technology talents.

What to pay attention to when using the cryostat
Shanghai Xinzhuang Instrument Co., Ltd. low temperature thermostat components and internal operating principles: 1, low temperature thermostat components: compressor, condenser, evaporator, fan (internal and external) circulating water pump, stainless steel liner, heating tube, intelligent temperature control table. 2, the internal operating principle of the low-temperature tank: after the compressor is operated, the suction-compression-exhaust-condensation-throttle-re-evaporation heat-absorbing vaporization. The water temperature is lowered to the temperature set by the temperature control table, such as temperature control. The table setting temperature is higher than normal temperature. The contactor in the temperature control table works automatically, giving the heating tube current signal, and the heating tube starts to work, when working in the low temperature bath. The inlet and outlet of the whole machine can be used to make internal or external circulation of the water source inside the machine, and the water source inside the machine can also be cited. A second constant temperature field is made outside the cryostat. How to use the low temperature thermostat This instrument uses 220V AC power supply. Please make sure that the rated current of the power socket is not less than 10A before use and have a safety grounding device (please connect the grounding device in the working room when using). When adding water, please pay attention to the upper cover not less than 8cm. You must use soft water, preferably distilled water. Do not use hard water such as well water, river water or spring water to prevent the heating tube from bursting and affecting the sensitivity of the constant temperature. Please use the temperature control instrument manual correctly, set the required temperature value> first turn on the power, set the desired temperature value on the meter according to the manual, when the temperature reaches the set temperature, you can turn on the cycle switch, so All programs go into normal working condition.
