Datacolor CONDITIONER™ (MB2) 06/2017 page 15/126
2. Cabinet description
The Datacolor CONDITIONER™ sample conditioning cabinet is equipped with a multifunctional micro-
processor display controller with 2-channel technology for temperature and humidity plus a digital display
accurate to one-tenth of a degree resp. 0.1% r.H. With its comprehensive program control functions, the
display program controller MB2 permits the high precision performance of temperature and humidity cy-
cles.
The sample conditioning cabinet with multifunctional microprocessor display controller MB2 is available in
two different types:
•
without light unit
•
with light unit
The sample conditioning cabinet is designed for exact conditioning of harmless materials such as paper,
textiles, plastics, building materials, to condition the samples at fixed temperature and humidity, so as
ensure no change in color of the samples occurs due to varying temperature and humidity
The APT.line™ preheating chamber system guarantees high level of spatial and time-based temperature
precision, thanks to the direct and distributed air circulation into the interior. The fan supports exact at-
tainment and maintenance of the desired temperature accuracy. Furthermore, it permits simulating exact-
ly and over long periods constant conditions for other applications such as sample conditioning for mate-
rial testing of paper, textiles, plastics, building materials, etc.
A resistance humidifying system humidifies the air. For this purpose, use deionized (demineralized) wa-
ter. The option BINDER Pure Aqua Service allows using the cabinet with any degree of water hardness.
The cabinet with lights unit is equipped with “Bio Vital” fluorescent tubes installed in two light cassettes.
They illuminate very homogeneously the racks below them. Both light cassettes are permanently con-
nected. The cable length permits easily removal to replace the fluorescent tubes. Control is effected via
the MB2 controller. Light is dimmable in 1% steps.
The inner chamber, the pre-heating chamber and the interior side of the doors are all made of stainless
steel V2A (German material no. 1.4301, US equivalent AISI 304). The housing is RAL 7035 powder-
coated. All corners and edges are also completely coated.
The inner chamber is closed by a glass door that enables the samples to be viewed for a short time with-
out disturbing the climate in the inner chamber.
All cabinet functions are easy and comfortable to use thanks to their clear arrangement. Major features
are easy cleaning of all cabinet parts and avoidance of undesired contamination.
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. The cabinet comes equipped with an Ethernet serial interface for computer communi-
cation. In addition, the BINDER communication software APT-COM™ 3 permits networking up to 30
chambers and connecting them to a PC for controlling and programming, as well as recording and repre-
senting temperature and humidity data. For further options, see chap. 23.5.
The cabinet is equipped with two safety devices to protect the unit, its environment and the samples in-
side from forbidden temperature excesses:
•
Electric safety controller
The sample conditioning cabinet is equipped with an electric over temperature safety device class 3.1
acc. to DIN 12880:2007. It is called a “safety controller”. It serves to protect the charging material
against extensive high temperatures. The safety controller is electrically independent from the main
temperature controller and takes over control when a selectable set point is reached.
•
Temperature fuse
The sample conditioning cabinet is equipped with a temperature fuse, class 1 acc. to DIN 12880:2007.
It serves to protect the unit and prevents danger caused by considerable defects. If a temperature of
about 110 °C is reached, the temperature fuse switches off the unit permanently.
