＜CO₂ control＞ Dimmable

Plant Growth Chamber

The CO₂ control function is added to the standard plant growth chambers.
Three-position controller is used for temperature and humidity control, providing energy-saving effects．This model can be used for research such as relationship between CO₂ concentration and plant growth rate.

Features

  • This model retains all functions of the model LPH-241/411PF(P/D/S)T-SP.
  • CO2 concentration can be controlled between atmospheric one and 3,000 ppm (controlled with addition of CO2).
  • Temperature, humidity, and illumination settings are done by using the touch panel mounted on the upper part of the door. 
  • Temperature, humidity, and illumination can be controlled by programming.

Applications

  • Plant cell/tissue culture, germination, acclimation, or growth tests
  • Growth of rice, arabidopsis, etc.
  • Insect experiments
  • Environmental tests

Options

  • Pressure Regulator with a flow meter
  • Table for a water tank  (Size:W300×D400×H900mm)
  • Evaporator for drained water 
  • CO2 removal unit
