＜Standard model＞ Dimmable

Plant Growth Chamber

This is an energy-saving model of a standard closed-type plant growth chamber, equipped with dimmable LEDs as standard.

Features

  • An operation touch panel with time display is mounted on the upper part of the main body, which allows easy operation.
  • Model L(P)H-□PF(S/D/P)T-S allows both constant operation at any temperature/light/ (humidity) and day/night switching operation.
  • Model L(P)H-□PF(S/D/P)T-SP allows a program control.
  • Five-sided illumination. The light can be continuously dimmed form 20% to 100% or 0%.
  • Model LHs don’t need a drain hose or a tank because of a forced evaporation system inside the chamber.
  • 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.”

Applications

  • Plant cell/tissue culture, germination, acclimation, or growth test
  • Environmental test
  • Growth of rice, arabidopsis, etc.
  • Insect experiment
  • Cell culture
  • Environmental resistance test for plants
  • Storage test at constant temperature and at constant humidity (only Model LPH)

Options

  • Table for a water tank (Model LPH)　(Size:W300×D400×H900mm)
  • Evaporator for drained water (Model LPH)

* Temperature sensor: platinum resistance temperature sensor, humidity sensor: polymer film capacitive sensor, humidifier: ultrasonic humidifier.
* The internal outlet of LPH-411PFST-S and LPH-411PFST-SP can be used up to 0.5A, while all other outlets 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.
* 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 under conditions of high temperature and high humidity, please contact us for confirmation.
