1.Unique design of the box within the wind circulation structure, to ensure that under the conditions of the test with the case of
uniformity within the box within ± 2 ℃

2.Unique design of the humidity test when the top of the box anti-drip design to ensure that live test from water short circuit,

surface water pollution

3.Using the latest environmentally friendly adsorption drying processor, effective control of the product when the surface
temperature condensation

4.The refrigeration room is fully sealed and soundproofed to reduce machine noise and box resonance, machine noise control within
