The low Temperature Test Chamber is a commonly used laboratory equipment for experiments and research in low temperature environments, such as freezing, cooling, heat preservation, and cooling of materials.
Selection points
Temperature range: Select the temperature range of the low Temperature Test Chamber according to the needs of the experiment or production. Generally, the temperature range of the low Temperature Test Chamber is between -40°C and -150°C. The temperature range of the low Temperature Test Chamber produced by different manufacturers may be different, and it needs to be based on demand Make a selection.
Temperature control accuracy: The control accuracy of the low Temperature Test Chamber is the key to ensure the experiment and production, so it is necessary to choose products with high control accuracy. Generally speaking, the control accuracy of the low Temperature Test Chamber is between ±0.1°C and ±1°C, the higher the control accuracy, the higher the price.
Box material: The box material of the low temperature test box includes stainless steel, iron sheet, aluminum, etc. The stainless steel material has the advantages of good anti-corrosion performance and convenient cleaning, but the price is relatively high, while the price of iron sheet and aluminum material is relatively low, but Does not have the properties of stainless steel.
Cooling method: The cooling methods of the cryogenic Test Chamber mainly include compressor refrigeration, liquid nitrogen refrigeration, etc. Different cooling methods have different advantages and disadvantages, and it is necessary to choose a suitable cooling method according to the experimental or production requirements.
Control method: The control methods of the low Temperature Test Chamber mainly include digital control and analog control. Digital control has the advantages of high precision, good stability, and convenient operation, but the price is also high. Analog control is relatively low in price, but control Accuracy is slightly inferior to digital control.
Box volume: Select the appropriate box volume according to the experiment or production requirements, the general volume ranges from 10L to 1000L.
