Selection of camera drying box?

I. Categories of electronic moistureproof box. Anti-mildew electronic moistureproof box for photographic equipment can be divided into two categories: low-temperature electronic moistureproof box and normal-temperature electronic moistureproof box. Automatic electronic drying oven at room temperature adopts suction electronic automatic moisture-proof system, which is the mainstream product of electronic drying oven on the market at present. Because it is suction dehumidification at room temperature, it has the characteristics that the dehumidification efficiency is not affected by the ambient temperature, and it can be dehumidified efficiently all year round. Even in winter, the humidity in the controlled space can be easily reduced to below 30%. Dehumidification can also purify harmful industrial waste gas in the controlled space, and the power consumption is only about 1/4 of refrigeration dehumidification, which is an energy-saving product. Secondly, how to choose the right electronic moistureproof box electronic automatic moistureproof box is a special product, which has special requirements for maintenance, such as the failure of memory alloy, which can't be repaired by general home appliance maintenance department, and the adjustment of sensors and hygrometers also needs a special artificial environment. Therefore, when purchasing, we should consider whether the product has reliable performance and the service life is as long as possible; Choose legal products with maintenance guarantee and reliable sources of spare parts in the future to ensure that the purchased products can be used for a long time and the maintenance is guaranteed. First, for non-professional photographers and a small number of camera collectors, the author suggests choosing the model of electromechanical integrated humidity sampling and control display (mostly using memory alloy spring-driven dehumidification valve to open, static dehumidification, mechanical hygrometer display) or electronic humidity sampling and control display (micro-motor-driven dehumidification valve to open, static dehumidification, mechanical or electronic humidity display). Although the humidity display of the independent mechanical meter is not accurate enough, due to the electromechanical integration control, the preset humidity range of the machine itself is not affected, and the automatic control accuracy is high. Secondly, for professional photographers or business occasions, try to choose a dynamic dehumidifier with fast dehumidification. The difference between static dehumidifier and dynamic high-speed dehumidifier is not very big, but the effect is far from each other. Moreover, the dehumidifying speed of the electronic automatic moistureproof box is also affected by the environmental humidity, which changes greatly. Things to be stored in the box in the future, or when things are often taken and put in the future, or some items with high water content are placed. If there is no room, once the door is opened, the humidity will drop in two or three days, which obviously fails to achieve the goal of optimal selection. Now some self-employed or small photo studios buy static dehumidification products because they want to save money. In fact, I opened the door several times a day to pick up and put the equipment, but the humidity has not dropped to a safe range, and the result is useless. In addition, try to buy a larger drying box to prepare for the increase of items in the future. Thirdly, for professional users who have high requirements for preservation conditions, users who are used to store valuables or important materials, and users who want to keep them for many years, they should try their best to choose professional-grade products that are driven by motors and adopt electronic humidity sampling, control and display. This is a large dynamic high-speed electronic drying oven. Compared with spending a little more money, the reliability of products and the long-term safety of stored items are the first.
