Thermo Precision Plant Growth Chamber

  • Catalog number PR505755L, model TFFU20F2QWA
  • 17.8 cubic foot chamber
  • Temperature range: ambient -10°C to +50°C
  • Programmable light and temperature cycles
  • 90 day warranty

The Thermo Precision Plant Growth Chamber features programmable temperature settings which enable users to input light cycles for a seven day program with up to two light cycles per day. Temperature is also programmable with a range of -10°C to +50°C with the lights off and +10°C to +50°C with the lights on. The Precision PR505755L plant growth chamber allows the user to program into memory 2 sets of values for time, setpoint temperature, and light condition per day for a full week.

The refrigeration system, defrost heater, and air circulating fan are used in conjunction with a microprocessor controlled proportioning circuit to achieve sensitive temperature control. An RTD (Resistance Temperature Detector) located in the airstream senses any temperature deviation from the control point, and heat is provided proportionally to maintain the desired temperature. Regardless of what temperature is being maintained, the compressor operates continuously. The circulating fan provides even air distribution throughout the chamber and ensures temperature uniformity.

All of our equipment is used and reconditioned. Our technicians test incubators using a calibrated digital chart recorder to verify the accuracy of temperature controls and readouts. We replace any hardware or parts as is necessary and clean all incubators thoroughly prior to shipment.
