Plant Growth Chamber＜Natural light model＞　 　　　Biotorn

■Natural light model (Temperature/Temperature & Humidity Control）

Model LH-240N is a plant growth chamber which can utilize natural light. This model is most suitable for the experiments using both artificial and natural light. Long-day treatment is performed by the illumination lamps equipped in four sides. 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 120 liters to 410 liters.

Operation Touch Panel



■Features

  • An operation touch panel with time display is mounted on the upper part of the main body, which allows easy operation.（N model）。
  • Easy to observe the inside, with double insulated glass and 5-sided structure. Suitable for experiments of plants or insects.
  • Model N can changeover between constant operation (temperature/illuminance [LH-□N], temperature/humidity/illuminance [LPH-□N]) and day/night switching operation.
  • Three-position controller is used for temperature and humidity control, which provides energy-saving effects.
  • Air circulation system allows good temperature distribution.
  • The inner door can be used as one door or two up-and-down doors as per usual, which allows a wide opening.
  • A hole of 40 mm diameter for measurement is included as standard (option for Model RD).
  • Humidity control system can be selected from “only humidification” or “only dehumidification” or “both humidification and dehumidification” (Model LPH).

■Applications

  • Plant cell/tissue culture, germination, acclimation, or growth test
  • Environmental resistance test for plants
  • Insect experiment
  • Storage test at constant temperature and at constant humidity (only Model LP)
  • Environmental test


■Options



■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)

# Temperature sensor: platinum resistance temperature sensor, humidity sensor: capacitance measurement sensor, humidifier: steam humidifier (LPH-240N) or ultrasonic humidifier (LPH-410N)
# When LH-120RD has a humidifier, the humidity may become constant above the set value.
# These chambers are designed to operate in ambient temperatures up to 30ºC. The specified performance may not be achieved depending on actual usage conditions.
# Depending on operating conditions, samples in the chamber may become dry.　
# When lighting, temperature setting should be 15ºC or higher.
# Power requirement does not include the power-outlet installed in the body.
# The specified performance may not be achieved depending on the combination of temperature and humidity.
