Composite salt spray test chamberprogrammingUsage：

One test cycle consists of a 4-hour salt spray test, conducted in accordance with DIN50021-SS

4-hour protection under standard climatic conditions, DIN50104-23/50-2 (including cooling phase)

Arrange a 2-day repair phase and use this test method to evaluate the corrosion characteristics that occur through salt, moisture, and temperature under static load.

Hardware of composite salt spray test chamberDesign points；

1. High quality composite material integrated molding to prevent equipment from deforming at high temperatures;

2. Control the opening and closing of the box cover, and easily start the box cover in an automated manner;

3. The front window allows for easy observation of the corrosion situation of the test sample;

4. Multi directional adjustment of the atomizing nozzle, making it convenient for users to find the atomization position of salt spray settling amount;

5. Adjustable speed peristaltic pump avoids the drawbacks of traditional atomization of salt spray through compressed air siphon, which makes it difficult to adjust the uniformity of sedimentation;

6. High resolution touch screen, visually displaying the operating status of various parameters;

7. The forced automatic defogging system avoids the traditional situation where the salt spray box cover can be opened at any time, causing salt spray to overflow and corrode laboratory and other equipment;

8. Automatic drying compressed air salt spray and saturated compressed air salt spray switching system to ensure the requirements of different salt spray testing standards;

8. Dry sealing completely isolates the communication channel between the box and the laboratory environment;

9. The large capacity salt solution tank meets the needs of the entire week's salt spray test;

10. Thoughtful random free fittings to avoid difficulties in connecting fittings of different global standards;

11.0.9 meters of low front design, convenient for testing engineers to access and place test samples;

12. The tilted front edge design inside the box increases the testing area and effectively utilizes the space inside the box;

13. Adopting the dry wet bulb method for humidity sensing

Control system software for composite salt spray test chamberfunction：

1. A concise and intuitive operating interface that facilitates users to observe the running status and data situation at any time;

2. The heating rate and PID changes can be observed on the touch screen, making it convenient to observe the heating and humidification during the testing process;

3. Compressed air saturated salt spray and compressed air dry salt spray can be switched freely to meet different salt spray testing needs;

4. The temperature and humidity change curve can be observed on the touch screen;

5. Temperature range timing function; You can set a temperature range, and the testing process will only be timed within this temperature range. It will not be timed below or above this temperature range.

6. Automatic defogging time setting; At the end or during the salt spray test, when it is necessary to open the box cover, the equipment will automatically blow out the salt spray inside the box to prevent salt spray from overflowing and corroding other equipment in the laboratory.

7. The temperature of the compressed air water saturator (bubble tower) can be set;

8. Turn on and off the fault alarm sound; To meet the preferences and needs of different users.

9. The temperature and humidity will operate according to the set temperature trajectory.

During the testing process, after the power is cut off, the test can be automatically restarted or manually restarted.

11. Calibration of temperature, humidity, and compressed air saturator temperature inside the box; When there is a deviation in temperature, humidity, or the temperature of the compressed air saturator inside the box. The deviation generated can be calibrated through the operation interface.

12. The standard configuration of the compressed air saturator is automatic water addition. And there are three-level water level sensors to ensure that the compressed air saturator will not overheat the heater without water.

13. Input and output port icon indication function; The operator can directly see the input and output status on the operation interface. It is of great help to maintenance personnel and remote problem solving during maintenance.

14. Remote networking function; This function can save the testing process data on the computer. There is no limit to the number of days to save.

The data saved on the computer can be saved in two forms: curve and EXCEL.

15. Automatic discharge of residual salt solution at the bottom of the container.

Precautions for operating the composite salt spray test chamberThis function is entirely designed to meet the needs of the G85-5 cycle salt spray test standard (SWEET cycle salt spray test) for automotive aluminum radiators. This testing standard requires that residual waste solution must be kept at the bottom of the container during salt spray testing The drainage pneumatic valve can be automatically closed to ensure that the waste solution remains at the bottom of the tank. When switching to other testing environment steps, the waste solution will be automatically discharged.
