Ⅴ,Chamber Structure
Overall structure and chamber was composed of three parts as below.

Insulation box, separate refrigeration units, and electrical control cabinet.

1．Insulation box
wall material: high-quality carbon steel with static color spray

inner wall material: SUS304 # matte stainless steel plate

Insulation materials: rigid polyurethane foam insulation layer + glass fiber.

2．Door Heating wire was installed at the door frames to prevent condensation
at low temperatures.
3．Observation window With 2 sets 350 × 500mm (width × height) observation
window, multi-hollow electric insulation coated glass prevent condensation
effectively
4．Cable port Φ50mm*2 located on both sides(each*1) with rubber stopper and
plastic cover
5．Lighting device 11W/AC220V *1 located on observation window
6．Water outlet hole Available for drain the condensate water
7．Sample holder Two layers of stainless steel sample holder.
8．Mobile Casters Mobile Casters *4 with foot cups
9．Electric control box Total power circuit breaker, over-temperature
protection.
