＜High-light intensity model＞ Dimmable

Plant Growth Chamber

This is Standard Plant Growth Chamber equipped with high-light intensity LED lamp on the ceiling.
You can choose the lighting from the following:
-White color: sun-like LED (SUNRAY LIGHT)
-Yellow/Pink color: LED for plant growth (PLANTFLEC)
Three-position controller is used for temperature and humidity control, which provides low running costs. Optimal program control can be achieved based on the specific requirements of the cultured plants. All types are capable of continuous dimming.

Features

  • 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).
  • Type -SPC: CO₂ control function.
  • Two-level wind speed control is installed to protect wind-sensitive plants.
  • The inner door has energy-saving functions, being used as one door or two up-and-down doors as per usual.
  • 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.”

All types are capable of continuous dimming.

* Temperature sensor: platinum resistance temperature sensor, humidity sensor: polymer film capacitive sensor, humidifier: ultrasonic humidifier, Carbon Dioxide Concentration Sensor: Non-Dispersive Infrared (NDIR) Spectroscopy Method.
* Power requirement does not include the power-outlet installed inside the chamber. The internal outlet can be used up to 1A.
* 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. 
* 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 under conditions of high temperature and high humidity, please contact us for confirmation.
* Due to differences in wavelength characteristics, the illuminance and luminous flux of each colors differ.
* Illuminance and photon flux density values measured on the lower shelf are average values.
* Due to PWM dimming control, flicker may be visible at low output settings.
