Rapid Temperature Change Test Chamber
  1. DESCRIPTION & SPECIFICATION

RAPID TEMPERATURE CHANGE TEST CHAMBER

FUNCTIONAL FEATURES

External test chamber is made of dual-side high-temperature electrostatic resin paint galvanized metal sheet, while internal test chamber is designed with SUS#304 high-low temperature resistance stainless steel material with its bottom with SUS#304 stainless as well as high-strength square tube connection reinforcement. 

Insulation material, in accordance with special heat-resistance purpose, is selected from frame retardant high strength PU polyurethane foam insulation material. 

Single door design with its size as width at 500mm and length at 600mm, is designed with observation window on test chamber door. Door frame is designed heat resistance, anti-frosting, anti-condensing devices to enable test technician have a good observation view of complete test process. 

Cable Hole (Test hole) with its diameter at 50mm on left of test chamber with silicone sealing and stainless steel cover is made and cable hole at 100mm for optional. 

To achieve an excellent test result, sealing process for test chamber is made with silicone rubber strip; sample holder with load-bear capacity of more than 20kg per layer. 

Air Supply System with constant air flow as well as uniform air distribution is driven by branded asynchronous motor, multiple-blades centrifugal circulating blower as well as high-performance sensors.
