This unit is not designed with explosion-proof structure.
Use extreme care when handling it.
For safety use
Do not put any inflammable materials such as
organic solvent into the chamber.
While operating the unit in high temperature,
sample in the chamber may vaporize, catch
fire and explode. Inflammable materials are
nitrates, nitro compounds, etc. and explosive
materials are chloride peroxides, inorganic
peroxides, salt nitrates, organic solvents etc.
This unit is not designed with explosion-
proof structure.
Dangerous
Caution
Do not touch the cooling fin with
your bare hands.
The cooling fin is very sharp.

The above performance has been obtained under conditions of 20℃of room temperature, rated power
source voltage, and without load.
The performance is indicated in conformity with JTM KO1-1998 (Testing method and indication form
for constant temperature and humidity bath by Japan Testing Machinery Association).
If the unit is operated at 30～40℃or lower temperature for a long time (one day～one week or longer),
please set “interval defrosting operation” for the operation.
The chamber temperature will go up by about 3℃, and the chamber humidity increase by about
20%RH, when the defrosting mode works under room temperature 20℃.
Actual changes of such temperature and humidity differ depend on actual operating conditions.
The chamber dimensions and overall dimensions without external tank do not include any projections.
The net weight includes external tank part and rack frame.
If the rack is not used, the net weight is about 127kg.
The required time to heat and cool, and to humidify, temperature and humidity control accuracy, and
temperature and humidity uniformity doffer depend on the environmental temperature, power source
voltage, with load or without load.

If the unit is operated at 30～40℃or lower temperature for a long time (one day～one week or longer), interval
defrosting operation must work. The temperature in the chamber is raised about 3℃, and the humidity in the
chamber is raised about 20%RH, when the defrosting mode works under 20℃of room temperature.
These variation differs depends on actual operating conditions.
