CBF / CBF-UL humidity control: The chamber is equipped with humidity control and a microprocessor-
controlled humidification system.
Freshwater is supplied by manually filling a freshwater bag, which is placed behind the chamber door in a
recess.
A resistance humidifying system humidifies the air. For this purpose, use deionized (demineralized) water.
The option BINDER Pure Aqua Service allows using the chamber with any degree of water hardness.
Controller: The efficient program controller is equipped with a multitude of operating functions, in addition
to recorder and alarm functions. Programming of test cycles is easily accomplished via the modern MB2
touch screen controller and is also possible directly with a computer via Intranet in connection with the APT-
COM™ 4 Multi Management Software (option, chap. 18.1). The chambers are equipped with an Ethernet
interface for computer communication. The APT-COM™ 4 Multi Management Software permits networking
up to 30 chambers and connecting them to a PC for controlling and programming, as well as recording and
representing temperature, CO
2
and O
2
and humidity data. For further options, see chap. 24.5.
