Product Overview/Applications

Meditech’s MT52 plant growth chamber is a compact yet highly configurable unit that is suitable for a wide variety of research and teaching programs. As a Floor Model design Meditech s Plant growth Chamber , it is easily accessed at standard bench heights and can be ordered with a bench kit complete with casters. The Plant growth chamber accommodates a 29” (740mm) growth height with 7 ft2 (0.6m2) of growth area. This facilitates growing a wide range of plants, including plant growth to maturity. Please consult Meditech regarding specific requirements of plant growth chamber.

Lighting
The standard lighting system on the MT52 plant growth chamber  provides a broad based light spectrum for plant growth using a combination of fluorescent and incandescent lamps. The lamps of plant growth chamber are housed within a barriered canopy which reduces heat transfer to the growth area. Excess heat in the canopy is ventilated to ambient. Standard light intensity is 400 micromoles/m2/s which is measured by a quantum light meter and transmitted to the controller for user readout. Standard lighting control provides two light levels per lamp type in plant growth chamber.

Airflow
Airflow for the MT52 is distributed uniformly upward using Meditech’s innovative Uni-floor air distribution plenum. The plant growth chamber includes fresh air intake and exhaust which are adjustable to allow up to 10 ft3/min (0.28m3/min.) of air exchange.

Refrigeration in plant growth chamber

Cooling on the plant growth chamber MT52 model is provided by a self contained air cooled condensing unit with hot gas bypass for continuous compressor operation. An electronic modulating valve provides tight temperature control while ensuring quiet operation of plant growth chamber. Pressure transducers are included for monitoring the status of the refrigeration system. Alternative refrigeration methods are available depending on site specific and/or user-defined requirements of Plant growth Chamber

Experiment Protection of plant growth chamber

User programmable “set and forget” alarms track the chamber’s operation versus user-defined set points . This allows for exceptionally accurate monitoring without the need for adjustment every time the set point is redefined. Backup “high/ low” alarms provide a further level of protection while visual and audible notification is provided when any alarm is activated in plant growth chamber. Contacts for connection to a building management system are also included on request in plant growth chamber
