Economical Salt Spray Environmental Test Chamber For Corrosion Resistance

 

Salt Spray Test is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.

Usually, the materials to be tested are metallic and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.

Control system:

 

Test chamber temperature control: Control the chamber temperature , according to standard, NSS AASS test is 35℃,and CASS test is 50℃.

 

Pressure barrel temperature control:Control the saturated air barrel temperature, NSS AASS is 47℃,CASS test is 63℃.

 

NSS AASS Test:Chamber temperature set 35℃, Pressure barrel temperature set in 47℃(40℃-50℃).

 

CASS test :Chamber tember temperature set 50℃, Pressure barrel temperature set 63℃(60℃-70℃).

 

Power switch:Control the whole machine power. Long press for power on or off.

 

Start/stop switch:Control the heating system of test chamber, heat sink and Pressure barrel.

Spray/pause switch:control the spray system.

 

Defog switch:control defog system, clear the salt mist in chamber after test.

 

Test chamber low water alarm:When the water level is low, the light will flicker . Add pure water into the test chamber until the light doesn^,t flicker.

 

Salt water tank low water alarm:When the salt water level is low, the light will flicker.Add salt water into the salt water tank until the light doesn^,t flicker.

 

Pressure barrel low water alarm:When the water level is low, the light will flicker.Add pure water into the pressure barrel nutil the light doesn^,t flicker.
