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)
