The purchase advice:
(1) Auto dry cabinet is a special product and has particular demand for repair. For example, the memory-alloy spring invalid is unable to be repaired in common electrical equipment maintenance shop, the transducer and hygrometer should be adjusted in special manual environment and this can't be done except for manufacturers. So you should choice the legal product which guarantee perfect repair service and reliable source of accessories to assure long-time use of this investment.
(2) Choice products with high dehumidify speed, that's dynamic dehumidify model, as possible as you can because dehumidify speed is influenced by the ambient humidity and the storing goods which are often changed frequently. If there's no plenty of space for maneuver, you'll regret that it should take two or three days to lower the humidity down when you put items in or out very frequently or store high moisture content goods in future. Nowadays there are some people bought static natural osmotic dry box for cheaper cause, but in fact they open door many times every day so the humidity hasn’t been lowering down to safe range and the dry box just exists in name only. In addition, choice the bigger one as possible because the bigger is more profitable than the smaller computing cost by “ yuan / liter” and you should leave proper space for possibly additional storing goods in future.
(3) Special users who request high quality storing condition or protect expensive items should choice as possible the special-class products that adopt electronic moisture sampling, control and display way. Comparing with the little more money, the reliability of product and the safety of items is the most important thing.
