FIELD: physics.

SUBSTANCE: test chamber has a housing divided by partitions into three compartments. The first compartment is for carrying out climatic tests. The first compartment has an air filter, sensors of parameters of the test object, a cooling system, a heating system and a ventilator. Outputs of the sensors of parameters of the test object are connected to inputs of a control unit, whose outputs are connected to control inputs of the cooling system, the heating system and the ventilator. The second compartment has high degree of air purity and has an air cleaning apparatus. The third compartment has an inlet lock with a vacuum cleaner, polluted air from which is released from the lock through a working hole.
