To put the lens, should I buy a moisture-proof box or an ordinary Lock box and put desiccant in it? Who can spread the knowledge about moisture prevention?

Of course, a moisture-proof box is convenient.

It is not impossible to prevent moisture by using ordinary Lock and desiccant. In fact, moisture-proofing is very simple. In a sealed cabinet, you can put a few packs of desiccant and moisture-absorbing beads into it, and it can be moisture-proof. But it is difficult to control the balance of humidity. Each item has its optimal storage humidity range. If the moisture-proof box cannot control the humidity range, too dryness may even be counterproductive and destroy the collection of items. For example: the storage humidity value of the SLR machine itself is required to be 45RH%. If it is too dry, the lubricating oil of the machine itself will evaporate and harden. The coating of the lens will also be seriously damaged due to excessive dryness, and the rubber parts will also crack due to excessive dryness.

Dr. Na subverts the traditional moisture-proof box's working mode of fixed and variable humidity

Adopts new dehumidification technology to dehumidify at fixed points to ensure stable humidity

● Our company's electronic moisture-proof box Cabinets, electronic moisture-proof cabinets, moisture-proof boxes, and moisture-proof cabinets are produced using the most advanced "semiconductor wafer refrigeration dehumidification" technology for civilian dehumidification. This technology absorbs and condenses water vapor in the cabinet into liquid through a semiconductor condensation device and discharges it naturally outside the cabinet. The principle of evaporation into the air.

● The movements of all electronic moisture-proof boxes, electronic moisture-proof cabinets, moisture-proof boxes, and moisture-proof cabinets are controlled by microcomputer technology. They are sensitive to humidity and have higher accuracy. They are intelligent detection control systems that will automatically detect Based on the changes in humidity in the box, the dehumidification time is intelligently adjusted to make the equipment run more stable and energy-saving. For example: Suppose you set it at 40%RH. After the equipment has been running for a period of time, the humidity will be controlled near the set value. When the humidity in the cabinet reaches the set value, it will automatically enter the constant humidity state. Only when the cabinet When the humidity in the body deviates from the set value by +3%RH, the system will work again and automatically turn on the dehumidification command. When it drops to 40%, it will automatically shut down. The constant humidity is accurate.

● The temperature and humidity data collection of this movement are all imported original components to ensure the accuracy of the collected data and are directly displayed on the LCD screen, which is more intuitive and error-free;

● The control panel adopts push-button humanized operation, which is simple and easy. The humidity can be freely set from 20-99% according to your own needs, tailor-made storage humidity conditions for your favorite things, and provide a more reliable and safe dehumidification environment.
