CONSTANT TEMPERATURE HUMIDITY TEST CHAMBER

CONSTANT TEMPERATURE HUMIDITY TEST CHAMBER

GENERAL INTRODUCTION--Constant Temperature Humidity Test Chamber 

Constant temperature humidity test chamber is mainly applied to test and verify materials,products in environment such as heat, cold,
Dry,humidity as well as other comprehensive environmental condition. 

Constant temperature & humidity test chamber can be used to test electronic, electrical,communication, instrument, automotive,
Plastic, metal,food,beverage, chemicals,building materials etc. by putting those products,parts,components in high low temperature,
Damp heat,constant temperature and humidity to verify their properties as well as parameter variants after environmental test. 

FUNCTIONAL FEATURES--Constant Temperature Humidity Test Chamber 

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 Port 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 asynchronousmotor, multiple-blades
Centrifugal circulating blower as well as high-performance sensors. 

Refrigeration System is introduced with French Tecumseh compressor for dehumification while Germany Bitzer compressor for
Refrigeration system,while use environmental friendly refrigerant HFC R404A, R23A. 

Heating System is designed with SSR Solid-State Relay controller to provide high accurate non-contact switch control, and the
Heating tube introduced with Naked Wire Nickel Chromium Alloy Electric Heating Tube. 

Control Method for walk-in Test Chamber is introduced with Programmable high accuracy micro computer controller, use cold mirror
Dew point instrument control temp. Humidity system. Cold mirror dew point instrument control temp. Humidity system.

P.I.D.,BTC balance temperature control method thermal compensation function DDC digital cold control DEC digital electric
Control Temperature change test program setting.
