We produce products available for use around the world, So one of the problems taken into account is the operational environment for the product.

Sand & Dust test adopts simulated asnd & dust environment to test the dust resistance of the product and to confirm whether the product can used for long in various hostile nature enviroment.

As is well-known, the product in working condition or in storage

condition, tends to be affected by various kinds of liquid more or

less. The osmosis, flow, impact or accumulation of the liquid may

have a variety of effect on the product material and performance,

and even may destroy its structure. Therefore, the affect from

liquid can not be ignored.

The purpose of rainfall test is to confirm the reverse osmose

capacity of the housing and its operation stabillity and reliablility

when or after the equipment undergoes liquid erosion.
