Plant Growth Chambers


Effective capacity
Temperature range
+5℃ to 50℃


Versatile Environmental Test Chambers

• Culture of plant cells, tissues and organs

• Acclimation and rearing of plants

• Incubation and rearing of insects*

Humidity control function (only for H type) suited for raising plants and insects

This holds an ultrasound humidifier controlled by a PID controller, making it able to control the humidity of an area of 60 - 90% RH(fluorescent light off).
Furthermore, it is able to humidify the chamber with the L-shaped humidifying pipe installed at the bottom of the chamber. From raising plants that hate dry, or high temp. high humidity environments to raising insects, it can create any humidified environment.

*The surface of the cooling device may rust by the excrement of the insects when putting many insects in the chamber. We recommend frequent maintenances.

Control panel

Graphic LCD panel with pop-up menu function on control panel provides more visual display and allows intuitive operation.

Top screen function

1. Menu selection
Scroll between chamber temperature, illuminance, and humidity screen using the down key.

2. Program selection
Choose between two modes - 24 hour clock mode, and count down timer mode.

3. Data log
Capable of saving the running data.

High capability of precise experiment and simulation Microprocessor PID + freezer function control

Microprocessor PID temperature control

This allows superior precise experiments. Electric control valve that can regulate the refrigerant flow control with the multi-programming function.
Microprocessor PID temperature control regulates settings and heat load in the chamber, and effectively runs the system Refrigerant flow regulates the quantity of dehumidification without lowering the temperature of evaporator and the fluctuation in the temperature ofinside the chamber became smaller.

Illumination program function for photomorphogenesis of plants and photosysnthesis study

Light steps

15 lamps of 40W fluorescent light are mounted on each facet of the both sides and the front door(5 lamps each). Light intensity is auto controlled with 6 increments in the range of 1 to 20,000lux (photon flux 0 to 150 μmol-2 S-1

*New fluorescent lamps used (FL40SS-W/37) *Please refer to the graphs for each illuminance.

*Characteristics may vary depending on the product or operating conditions.
*Product certificate issuing is a paid service. This does not include the temperature uniformity data.

Easy handling and maintenance

Since three doors with lights can be opened and closed, the maintenance of the florescent lights is easy. The structure prevents outside light from entering. The inner dimension is 520mm(w) x 490(d); most shakers, rotators, and stirrers can be used. The upper left of the main unit has an inspection hole, and is equipped with a power plug.

  • Microprocessor PID temperature control system provides low temperature fluctuations, and accurate temperature control. Allowing superior precise environment, and reduced power consumption.
  • Temperature programming function is best suited for the temperature cycle, and especially for the Spring program.
    ・Max. 12 steps (10 patterns ) storable
    ・Choose from the clock mode, and the timer mode
    ・Join function to run several programs, Spring, Summer, and Autumn, continuously
  • Approximately 2 weeks of running records can automatically be recorded when the data is saved at a 6 minute log interval ・View the recorded data on the display through the control panel
    ・Data transmits (CVS) to PC, an optional communication terminal MTR-480. ( 9 pin cable Dsub cross type for R232C needed)
  • Easy calibration Temperature and humidity calibration can be done on the control panel
