Plant Growth Chamber

LPH-411PFDT-SP

This is an energy-saving model of a standard closed-type plant growth chamber, equipped with dimmable LEDs as standard.
You can choose the lighting from the following:
-White color: sun-like LED (SUNRAY LIGHT)
-Yellow/Pink 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. You can choose between the 240L and 410L sizes.

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).
5-side irradiation with continuous dimming from 0% or 20% to 100%.
Type LH does not require a drainage system due to its built-in forced evaporation system.
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.”
