Product Description


YG751D Constant Temperature Humidity Chamber, used to conditioning of samples prior to testing. It also can be used for a variety of materials of high – low temperature alternating test. The test temperature, humidity and time can be programmed.



  1. Touch screen, South Korean import,900 temperature controller
  2. Control mode: Touchpad
  3. Display: Touch display, Korean TEMi880, programmable.
  4. System capacity:120 groups program X100 sections, required segmentation sections of each group can be arbitrarily divided and
  5. Each program can freely link another.
  6. Cycle setting: each operation procedure can carry out 9999 times or heaps of times cycle and repeated performance, and to the degree, divide further 5 segmentation sections to do part cycle of the extra.
