The RH-500D allows to recreate two different environments in two chambers, for a volume reaching 620L. The conditions are uniform and stable. The chambers are well insulated to avoid heat transfer between them. The RH-500D is made in robust anti-rust material. Fully programmable, temperature, humidity and different gas in option. Lights can be added in every chambers as UV fluorescent lamps or UV LED. The air circulation is Side to Side air circulation for an excellent uniformity.
