Application of Salt Spray Tester TU380

Salt spray machines are also known as salt spray cabinets, salt spray chambers, and salt spray test machines. Salt Spray Tester Chamber provides a high salt spray environment to measure the corrosion resistance of many materials, such as paints, coatings, steel, and so on over a set period of time. In addition, the salt spray machine is used to spray Sodium chloride solution on the electrophoretic coating surface, in order to carry out the corrosion testing. Compared to the natural environment, the salt spray tester offers a much higher corrosion rate and a much shorter salt spray test time.

Besides, this Salt Spray(Fog) Apparatus is intuitive to use and suitable for varied testing labs. Accordingly, there are many companies trying to manufacture such salt spray chambers. TESTEX also applies this salt spray cabinet to test the quality of our equipment with high quality and stable operation like the TF416A perspiration tester.

What is the Salt Spray Test?

The salt spray corrosion test consists of two types. One is natural exposure and the other is machine simulation. Salt spray tests mainly use salt spray equipment to simulate the manufacture of a salt spray environment. Besides, the more time it takes to corrode the material, the more potent corrosion of the sample has. When the test finishes, we can get an accurate result. The main factors influencing the results of the salt spray test include the temperature and humidity of the salt spray test, the concentration of the salt solution, the angle of sample placement, the pH value of the salt solution, the amount of salt spray deposition, and the way of spray, etc.

The artificial simulation salt spray test is a kind of salt spray chamber with a certain volume space and in the space of the salt spray test chamber, we use the artificial method to test the product’s salt spray corrosion resistance in accordance with the salt spray test standard.

  1. Jeffson

    this instrument is very robust to create a salty environment

  2. Sampson Pulitzer

    Works great! Very economical. The only reason I gave 4 stars is because the delivery time is a bit long.

  3. Nathan Locke

    Excellent Salt Spray Tester at a super price.

The Danger of the Corrosion

Corrosion is a natural process in which materials deteriorate when they interact with their surroundings and environments. There are many reasons for the formation of corrosion. Among them, an electrochemical reaction is the most common cause of corrosion. Most or all of the atoms are oxidized, ruining the entire surface gradually. Worst, corrosion becomes a serious problem, giving rise to the collapse of buildings, fires, and other problems. Salt spray corrosion will harm the metal protective layer, making it lose ornamental quality and decreasing its mechanical strength. Some electrical components and electrical lines will suffer from the interruption of power lines due to corrosion. Especially when they are in the natural environment with vibration, they will meet with serious corrosion. It is more possible to make the moving parts not work normally if they encounter corrosion. As a result, it is necessary for us to prevent corrosion and test the corrosion resistance.

The Significance of Salt Spray Test

A salt spray test is an important means to evaluate the corrosion resistance of products or materials by providing a controlled corrosive environment so as to obtain the relative corrosion resistance information for specimens of metals and coated metals in the given space. Besides, the rationality of the test result is of great importance. However, the salt spray results are seldom related to the predicted result of performance when the sample is put into natural environments and the predicted result is taken as stand-alone data. And the results of the salt spray test can provide effective information for material selection, structural design, process selection, product transportation, product storage, and use, and ultimately improve the corrosion resistance of products or materials.

Salt Spray Test Standard

Salt spray test standards mainly include salt spray test standard ISO 9227, ASTM b117 standard pdf, GB/T 2423.17 standard, and so on. In the case of the ASTM b117 salt spray test, because of the complexity of the actual environment, it does not specify the ASTM b117 salt spray test hours required for the test of the sample.

ASTM B117:Standard Practice for Operating Salt Spray (Fog) Apparatus.
ASTM B117 test method contains the apparatus, procedures, and conditions required to establish and maintain the salt water spray test environment. It also provides a controlled corrosive environment.

GB/T 2423.17:Environmental testing of electrical and electronic products

GB/T 2423.17 standard specifies the basic environmental test of electrical and electronic products salt spray test method.
This standard applies to the assessment of materials and their protective layer of the ability to resist salt spray corrosion, as well as a similar protective layer of process quality comparison, which can also be used to assess the ability of certain products to resist salt spray corrosion.


1 Replace the water in the heat sink if the test lasts more than one month.

2 If the salt solution is not used over one week, do not use it again, so as not to affect the test.

3 If the next test takes a long time, clean up the test chamber, and discharge the water in the tank.

4 Please replace the glass nozzle per 2000 hours test, in order to ensure the test quality.

As professional salt spray test chamber manufacturers, we use salt spray test chambers to check each salt fog test chamber in accordance with the salt spray chamber specification to ensure that it works properly. If you want to know more, such as the salt spray test procedure, salt spray test chamber price, etc., please contact us.

Fault and handling methods

Because the salt fog tester has been conducting salt fog aging tests for a long time, it is likely to be many failures or be out of work. Here are some common failures and handling methods.

The laboratory temperature cannot rise to the set one.


1 The set temperature of the laboratory temperature controller is too low.

2 The safety protection switch in the laboratory is set too low.

3 The heating system, electromagnetic relay, and controller go wrong.

Handling methods:

1 Set the temperature controller to the required temperature;

2 Set the safety switch to the required temperature;

3 Notify the maintenance company for on-site repair.

Unable to spray


1 The air compressor is not running;

2 The main switch of the air compressor outlet is not opened;

3 Solenoid valve and electromagnetic contactor go wrong.

4 The pressure gauge fails to work or the pressure is too low;

Nozzle clogging

Handling methods:

1 Turn on the air compressor button;

2 Turn on the main switch of the air compressor;

3 Notify the maintenance company to carry out on-site repair;

4 Remove the nozzle for cleaning (please disassemble it carefully)

Fail to work even though the power turns on

Failure cause: The power supply for operation will be cut off when the water level in the heating tank is too low.

Treatment method: increase the water level of the heating tank to the normal level.

    Q: Is the Salt Spray Testing Chamber capable of maintaining 50º C +/- 1º C and above 85% relative humidity?

    A: Humidity can reach 95%.

    Q: What is the difference between using this instrument to test and just putting sample into a salt box in a very simple way? Why?

    A: The test result of this instrument will be more close to reality life than the salt box, because the instrument uses spray to test, and the sample will be fully exposed to air and sprayed with salt at the same time.

    Q: Do you offer ASTM B117 salt spray test PPT or ASTM B117 salt spray test PDF free download?

    A: Sorry, we don't have a special ASTM B117 PDF free download, but if customers need, we will make it special.
