Monitoring air quality

I am looking for the instrument which could monitor the storage
room's air. Since one of my storage rooms is full of wooden
material, I am wondering about the off-gassing problem. Therefore, I
am looking for  a kit or instrument to test the air in the storage
rooms. Also, I wish the equipment could read out  the harmful
particles which are inside the storage rooms. If anyone knows it,
please contact with me. Thanks.  Sincerely,
