The invention discloses salt mist test equipment. According to the salt mist test equipment, one end of a water pump (5) is communicated with the inside of a transparent water tank (4), and the other end of the water pump (5) is connected to a water nozzle (1); a gas pump (6) is communicated with a gas nozzle (2), and a gas outlet end of the gas nozzle (2) and a water outlet end of the water liquid nozzle (1) are perpendicularly arranged; scales are formed in the outer side of the transparent water tank (4). The salt mist test equipment solves the problem that a prompt cannot be given timely when the capacity of salt water is low in the prior art, visualization of the salt water capacity is realized, and salt water can be added at any time.
