The Thermo Forma 3940 is a current model environmental chamber offering humidity and temperature control. These units retail for approximately $19,000 in new condition. These units had an LED rope taped to the inside (now removed) but adhesive tape residue does remain.
Please note that these units take 220V power and so will not work with standard 110V receptacles. We can configure the power cords to fit your receptacle upon request.
