The invention discloses a conveniently regulated salt 
fog corrosivity 
test chamber. The 
test chamber comprises a pedestal, the top end of pedestal is provided with a bottom box and a controller, the inner side of the bottom box is provided with a 
smoke generator, the top end of the 
smoke generator is provided with a 
smoke conveying 
pipe, the inner side of the bottom box is provided with a 
water leakage incline plate, the bottom end of the 
water leakage incline plate is provided with a connecting 
pipe, the bottom end of the connecting 
pipe is provided with a water collecting box, the inner sideof the water collecting box is provided with a condenser pipe, one end of the condenser pipe runs through a side wall of the bottom box and stretches to the outer side of the bottom box, one end of the condenser pipe is connected with a compressor, the other end of the condenser pipe is connected with an 
evaporator, and one side of the compressor is connected with the 
evaporator. The salt 
fog corrosivity 
test chamber is provided with the 
water leakage incline plate, the water collecting box and a measuring cylinder, thereby avoiding the problem that when the salt 
fog corrosivity test chamberis used, 
salt water is difficult to add in the salt fog corrosivity test chamber timely according to the reduced quantity of the 
salt water so that the use convenience of the salt fog corrosivity testchamber is influenced.
