Salt spray test is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its suitability in use as a protective finish. The appearance of corrosion products (oxides) is evaluated after a period of time. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period in testing without showing signs of corrosion. Different coatings have different behaviour in salt spray test and consequently, test duration will differ from one type of coating to another.

 

 Characteristics:

 1. the spray nozzle the heart of tester adopt Bo Nute Principle which change saline water into atomization but no crystallization produced.

 2. the controller is digital type microcomputer which delivers precision temperature

 3. parameters show on the display screen such as temperature, humidity, pressure, spray capacity and time.

 4.test specifications are accept worldwide.
