    What is a SALT SPRAY CHAMBER ?

    ATMARS Salt spray chambers or salt spray cabinets are designed to perform salt spray test(salt fog test or salt mist test) on surface coatings or materials in a highly corrosive environment (mainly sodium-chloride, NaCl) through pressureized spray nozzles to check the corrosion resistance of surface coatings or coverings for products usually made from steel, brass, and other metals.

    The test results recorded through the process of salt spray testing can show the process of product decay and degradation and help predict the potential lifespan of a product or coating.

    Relevant salt spray testing standards are ASTM B117, ISO9227, JIS Z 2371 and ASTM G85.

    And there are 3 common Salt spray tests -
    NSS: Neutral Salt Spray Test
    AASS: Acetic Acid Salt Spray Test
    CASS: Cupric Acid Salt Spray Test

    NSS is the base of salt spray test, it was developed at around 1930s, it is a neutral test which means the test solution pH value is at 6.5-7.2.
    AASS is the method in NSS solution with addition of glacial acetic acid in the pH range of 3.1 to 3.3.
    CASS is the method in AASS solution with addition of copper chloride in the pH range of 3.1 to 3.3.

    ATMARS Salt Spray Chamber Premium Models -
    ATMARS premium models can perform the same basic salt spray tests, but in addition are equipped with extra features which enable them to undertake modified salt spray tests such as those defined in ASTM G85.
    Here conventional salt spray is often combined with one other climate, in a two-part cycle, to accelerate the test. For example: salt spray and condensation humidity (SWAAT) or salt spray and drying (PROHESION) or salt spray and SO2 testing.

    ATMARS salt spray test chambers Standard workspace volumes include 108L, 270L, 480L, 800L and 1200L.

    DefoggingThe mist is exhausted by air extrusion, and the cover (canopy) is tapered to form a top angle of 120 ° C, which is beneficial to the droplets generated by the salt spray not directly dropping on the sample, thereby ensuring the accuracy of the test.

    Safety1. Low water level protection, the power supply will automatically cut off and meanwhile the safety warning light device will display automatically;
    2. Over-temperature protection, the heater power supply will automatically cut off , and meanwhile the safety warning light device will display automatically;
    3. Low water level of saline, the safety warning light device will display automatically;
    4. Leakage protection function to prevent personal injury and instrument failure caused by line leakage or short circuit.
    ▲Custom options are available.
