~Application:
Constant temperature and humidity chamber is made up of control panel, switchboard, insulation storehouse board, forced draught blower, heater, humidifier and refrigerator. Offer large-scale part, semi-manufactured goods, finished product, temp & humidity environment test for the manufactory, for instance; computer terminal machine, automobile part. 
 
Features:
 
  1. The appearance can use different colors or all stainless steel according to the interior design, the interior is made of SUS304# stainless steel.
 
  2.  Rectangular multi-layer glass view window is used to observe the test products in the testing. The window with anti-sweat electric heater device can prevent condensation water droplets.
 
  3.  Indoor installs explosion-proof light which can let people clearly observer product test condition and it is safe to use because of the installation of non-slip aluminum plate at the bottom of the laboratory.
 
  4.  The door's double insulated seal strip can effectively isolate internal temperature leakage.
 
  5.  The pure water filter unit directly filters tap water; it is easy to use and doesn't need to add water manually.
 
  6.  Refrigeration and dehumidification system uses imported brand compressor, with the advantages of energy saving, low noise, low energy consumption, and stable performance, and uses environmental protection refrigerant (R23, R404a).
 
  7.  Controller is designed by doahoo,shanghai,china, can simultaneously display measured value and the set value, time, etc.
 
  8.  Controller has multi-segment program, so editing and temperature and humidity can quickly and sloped control.
 
  9.  The doaho touch screen display with RS-232/RS-485 communication interface, 2GB standard SD memory card can connect to Ethernet.
 
  10.  The bottom of the machine uses the channel to weld into a mesh structure in order to increase the load-bearing, it will never deform; the bottom of the unitary testing chamber installs mobile casters and positioning goblet; the channel at the bottom of compositional testing chamber directly installs in the ground of laboratory.
