The temperature control system of the high-precision low-temperature constant temperature bath adopts PID temperature control technology, and the accuracy can reach 0.01°C. It adopts a corrosion-resistant stainless steel inner tank, and the volume is optional from 7.5L to 30L. One-click to open the large-screen LCD display, and the setting temperature and display temperature are clear The display is easy to operate, and the microcomputer system is convenient to correct the error between the displayed temperature and the actual temperature. The temperature correction resolution is as high as 0.001°C. The microcomputer intelligent control system has the abnormal protection function of the temperature sensor to ensure the safety of the experiment. The high-precision low-temperature constant temperature tank control system has an over-temperature beep alarm, which can set the upper and lower limits of the over-temperature alarm temperature, and can automatically cut off the load when the temperature is over-temperature. Optional RS232 or RS485 communication interface can be used to communicate with PCs or PLCs. Data transmission, long-distance control, optional inner tank liftable bracket to achieve height adjustment of special experimental samples, and optional thermometer insert.
In addition to biology, the important characteristics of many materials in high-precision low-temperature constant temperature baths also have an important relationship with temperature: for example, mechanical materials have cold brittleness, plastics and rubber have the same properties; and for example, the conductivity of metals increases with temperature. Metals or alloys appear superconducting when the temperature drops to a certain value. Artificially using these properties requires artificially creating a low-temperature environment. The change of state of matter occurs through cooling, which can separate the mixed gas and liquefy the gas.
Diffusion and chemical reactions are also directly related to temperature. In many production processes, temperature has a great impact on product performance and quality. Choose the appropriate volume for the intelligent low-temperature constant temperature tank. The size of the general tank is between 5-30l. You can choose according to your own According to the requirements of the experiment, the Water Tank with the corresponding volume should be selected according to the scale of the experiment, so that the experiment can go smoothly.
High-precision low-temperature constant temperature bath is widely used in research departments such as petroleum, chemical industry, electronic instrumentation, physics, chemistry, bioengineering, medicine and health, life science, light industry food physical property testing and chemical analysis, colleges and universities, enterprise quality inspection and production departments , to provide users with a controlled hot and cold, uniform and constant temperature field source when working, to conduct constant temperature experiments or tests on experimental samples or produced products, and can also be used as a heat source or cold source for direct heating or cooling and auxiliary heating or cooling .
Specific precautions for high-precision low-temperature constant temperature bath:
1. Add liquid medium into the front tank of the high-precision low-temperature constant temperature tank. The liquid level of the medium should be about 30mm lower than the worktable, otherwise the heater will be damaged when it is powered on;
2. When the working temperature of the high-precision low-temperature constant temperature tank is high, care should be taken not to open the upper cover and not to enter the tank with hands to prevent burns;
3. Power supply: 220V50Hz, the power of the power supply should be greater than the total power of the instrument, and the power supply needs to have a good "grounding" device;
4. The selection of liquid medium in the high-precision low-temperature constant temperature bath should comply with the following principles:
When the working temperature is 5-85°C, the liquid medium is generally water;
When the working temperature is 85-95°C, the liquid medium can be 15% glycerin aqueous solution;
When the working temperature is higher than 95°C, oil is generally used as the liquid medium, and the flash point value of the selected oil should be 50°C higher than the working temperature;
Note: The working temperature here refers to the temperature to be reached by the liquid medium in the tank;
5. The instrument should be placed in a dry and ventilated place, and there are no obstacles within 300mm around the instrument;
6. After use, all switches are turned off and the power is cut off.
