＜Standard model＞ Dimmable & Dual-Color LED

Plant Growth Chamber

This is Standard Plant Growth Chamber equipped with alternating White color: sun-like LED (SUNRAY LIGHT) and Yellow color: LED for plant growth (PLANTFLEC).
Environmental control can be adjusted to meet research needs, such as short-day and long-day treatments. There are two types of control system: Changeover between constant operation and day/night switching operation or Program control. Three-position controller is used for temperature and humidity control, which provides low running costs.

Features

  • This is an energy-saving model of a standard closed-type plant growth chamber, equipped with alternating Plantflec Yellow and SUNRAY LIGHT LEDs.
  • An operation touch panel with time display is mounted on the upper part of the main body, which allows easy operation.
  • Type -S: constant operation at any temperature/light/ (humidity) and day/night switching operation.
  • Type -SP: program control (real-time mode / accumulated operation time mode).
  • 5-side irradiation with continuous dimming from 0% or 20% to 100%.
  • Three-position controller is used for temperature and humidity control (proportional control for heating), which provides low running costs.
  • The inner door has energy-saving functions, being used as one door or two up-and-down doors as per usual.
  • Two-level wind speed control is installed to protect wind-sensitive plants.
  • A hole of 40 mm diameter for measurement is included as standard.
  • Humidity control system can be selected from “only humidification” or “only dehumidification” or “both humidification and dehumidification.”

* Temperature sensor: platinum resistance temperature sensor, humidity sensor: polymer film capacitive sensor, humidifier: ultrasonic humidifier.
* Power requirement does not include the power-outlet installed inside the chamber. The internal outlet can be used up to 0.5A.
* These chambers are designed to operate in ambient temperatures 15 to 30℃ in general. The specified performance may not be achieved depending on actual usage conditions.
* Supply purified water (disilled or reverse osmosis water) only.
* The specified performance may not be achieved depending on the combination of temperature and humidity.
* Depending on the sample, drainage installation may be required.
* When lighting, temperature setting should be 15℃ or higher.
* Keep 30cm or more clearance at both sides and the back of the product to prevent exhausted heat from being trapped and hindering the cooling function.
* The specified control accuracy for temperature and humidity applies when lights off.
* For long-term operation at high temperatures, please contact us for confirmation.
* The specified performance may vary depending on the installation environment, settings, and the placement of samples and other conditions inside the chamber.
