SRI21D SHEL LAB Diurnal Plant Growth Chamber

Request Info


SHEL LAB Diurnal growth chambers are designed for studies requiring day and nighttime simulation. This unit features dual-program selector dials, which allows control of two temperature conditions and an ON/OFF illumination cycle relative to the program selected. Each system operates independently allowing for simulation of a diurnal cycle, such as an eight hour day cycle of 30°C with light followed by a sixteen hour night cycle of 18°C without light. Forced air circulation ensures the most reproducible test conditions. The chamber air is gently and continuously circulated at a rate that ensures temperature uniformity of all test samples.

The unit is equipped with a hermetically-sealed compressor and an independent over temperature safety controller. In addition, a one amp interior outlet allows use of shakers, stirrers, roller bottles or other apparatus. Units include:


  • Day/Night Light and Temperature_Control
  • Microprocessor Control
  • LED Display of Set point and Chamber Temperature
  • High and Low Limit Temperature Protection
  • Interior Electrical Outlet
  • Fan Assisted/Forced-Air Circulation
  • Hermetically Sealed Compressor
  • 24 Month Limited Warranty
