Plant Growth Chamber SMI-139

Jindal Plant Growth Chamber is state-of-the-art equipment for plant growth and animal studies. It is used in many research, education and agricultural industries. The chamber is used for a material test in a constant climate, specifically the stability test in accordance with the ICH (International conference on halmonisation of technical requirements for registration of pharmaceuticals for Human use). The combination of technology for heating, cooling and dehumidifying, as applied by the Jindal New Modular Plant Growth chamber is so far unique on the market. The inbuilt provision for light, temperature and humidity are made to test plant growth and analyse their flowering cycle.





 Construction

The inner chamber is made of Stainless steel and the outer body is made of mild steel duly powder coated. A see through window is provided for inspection of plants without disturbing the thermal conditions. Adjustable stainless steel trays to place the samples are provided.



 Insulation

The inner stainless steel chamber is insulated by high density thick polyurethane foam insulation to prevent thermal losses.



 Heating

The heating is done by finned heaters to maximize heat exchange process and to achieve the set temperature in a short time interval.



 Cooling

The cooling is done by a highly efficient hermetically sealed refrigeration unit with air cooled condenser & CFC free eco friendly refrigerant to achieve set temperature in a short time period.



 Illumination

Provision from 10,000Lux to 50,000Lux illumination is done with a mixture of incandescent lamp and fluorescent light to give effect of day light.



 Air Circulation

Highly efficient forced air type circulation with motor blower assembly is provided to maintain uniform temperature inside the chamber.



 Fully Automatic Microprocessor Control

The new modular design of plant growth chamber is integrated with a multifunctional fuzzy controller with an integrated self diagnosis system and high quality platinum sensors. The fuzzy controller allows precise adjustments of temperature/humidity constellations, greater stability of the variables over long periods, which are of crucial significance.



 Technical Specifications
  • Temperature range 0C to 70C with a display and setting accuracy of 0.1C.
  • Over and under temperature protection temperature controller takes over control in case of failure of the primary controller. This controller can be set freely within the tolerance range for over and under temperature.
  • Humidity range from 45% RH to 95%RH with a setting accuracy of 0.1%RH.
  • A high grade PT-100 sensor for temperature measurement, capacitive sensor for humidity measurement is used for stable and long term transmission of measurement signals.
  • Bright and large LCD to display all the set and the process parameters along with the visual messages.
  • In built Real time Clock.
  • In built programmable switching of fluorescent light.
  • Visual & Audio Alarm in case of over /under temperature, humidity & empty water tank.
  • On board RS-232 port for data acquisition.
  • Programmable weekly timer.
  • Minimum Power Consumption Algorithm:
    Even though the growth chamber consists of a high wattage heater to act to any settable temperature quickly but it uses only a fraction of heater wattage when the chamber temperature reaches near to the set temperature thereby saving a lot of energy. This is achieved by using the heating circuit with a thyristor in a current control mode driven through the microprocessor. This control provides a soft start for the heaters thereby prolongs the heater life.
  • The menu is driven through the microprocessor with password protection to ensure that no manipulation can be done while operated by an un-authorized person.
  • In built battery backup along with charger for display of the actual parameters.
  • Data Retentive Timer for the processes ensures the incubation of material for the required time only.
  • Feather touch keyboard for setting temperature, humidity and other parameters.

 Optional Features
  • Internal log memory to store the error states history for temperature and humidity with time and date.
  • Remote machine monitoring and its operation through cell phone.
  • In built serial Thermal printer (Both Text and graph mode).
  • Low/High Voltage detection & safety cut off feature.
  • Memory card log with 500MB memory.
  • Temperature profile control consisting of 40 or more ramps.
  • CO2 injection and control with a highly accurate dual beam IR sensor and solenoid valve control.
  • Touch screen control
