Plant Growth Chamber

The Plant Growth Chamber is an energy-efficient, closed-type environmental chamber designed for precise plant research and controlled growth studies. Equipped with dimmable LED lighting, it offers a choice of sun-like white LEDs (SUNRAY LIGHT) or plant growth LEDs (PLANTFLEC) to suit different research applications. Researchers can easily simulate short-day and long-day conditions with flexible environmental controls.

Available in 240L and 410L capacities, the chamber features advanced temperature and humidity regulation with either constant/day-night operation or programmable control, ensuring stable environmental conditions while minimizing energy consumption. It is an ideal solution for agricultural research, plant physiology, biotechnology, and life science laboratories.

Notes

All models support continuous LED dimming for precise light intensity control.
Temperature sensor: Platinum resistance temperature sensor. Humidity sensor: Polymer film capacitive sensor. Humidifier: Ultrasonic humidifier.
The internal power outlet of LPH-411PFST-S and LPH-411PFST-SP supports equipment up to 0.5A. All other models support up to 1A.
These chambers are designed to operate at an ambient temperature of 15°C to 30°C. Performance may vary depending on operating conditions.
Use only purified water, such as distilled water or reverse osmosis (RO) water.
Specified performance may vary depending on the selected temperature and humidity settings.
Depending on the sample type, a drainage installation may be required.
When the lighting system is in use, the temperature should be set to 15°C or higher.
Maintain a minimum clearance of 30 cm on both sides and at the rear of the chamber to ensure proper ventilation and cooling.
The specified temperature and humidity control accuracy applies when the chamber lights are turned off.
For long-term operation under high temperature and high humidity conditions, please contact us for confirmation.
