The RH-400L has the particularity to manage the temperature from -40°C to +100°C. A perfect insulation done in three layers limit the air exchange ratio with the environment. To not disturb the inner environment of the chamber and allow a full observation the RH-400L has a double glass door.
Two access ports from the front glass door and three other side access ports for a total control and monitoring of the environment. The chamber is done in full high grade stainless steel to avoid any point of rust. The controller of the chamber allows of course the perfect control of it.
