Plant Growth Chamber <Standard model>　　　　　　 　Biotron

■Only Temperature Control/Temperature & Humidity Control　L(P)H-241/411S(P)

Models L(P)H-241/411S(P) are standard plant growth chambers, which can control environment including short-day treatment or long-day treatment depending on research fields. There are two control modes available. One is a changeover mode, changing between constant operation and day/night switching operation. The other is a program control mode. Three-position controller is used for temperature and humidity control, which provides energy-saving effects. A wide variety of chambers are available in sizes ranging from 240 liters to 410 liters.

model LH-241SP

model LPH-411SP

■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-XXS allows both constant operation at any temperature/light/ (humidity) and day/night switching operation.
• Model L(P)H-XXSP allows a program control.
• Five-sided illumination.
• 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.
• L(P)H-241/411S(P) provides high intensity illumination of 31,000 lx.
• The inner door has energy-saving functions, being used as one door or two up-and-down doors as per usual (Model 241/411).
• A hole of 40 mm diameter for measurement is included as standard (Model 241/411).
• Humidity control system can be selected from “only humidification” or “only dehumidification” or “both humidification and dehumidification” (Model 241/411N).
  
  
  

■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), network observing system, 3-in-1 LED illumination, metal halide lamp, carbon dioxide removal unit.
  

■Safety devices

• Overheat prevention: thermal fuse, overheat thermoswitch (variable), alarm buzzer.
• Overcool prevention: overcool thermoswitch (variable), alarm buzzer.
• Earth leakage breaker.
• Protection device for refrigerator (overload relay)
