The salt spray test chamber is suitable for salt spray corrosion tests on components, electronic components, protective layers of metallic materials and industrial products. In addition to the ambient temperature requirements of less than 30 °C, the following appearance requirements should be strictly observed during the test. The following are the aspects to be noted when testing the salt spray chamber of Kunshan Haida Instruments.

1. Materials in direct contact with saline solution and salt spray in the test box should not react chemically with saline solution and salt spray, and parts that are not in direct contact should be resistant to salt spray corrosion.

2. Salt mist should not be directly injected onto the test sample.

3. Drops on the top and inner walls of the box should not drip in the studio.

4, the pressure from the balance of the fog tube must be ventilated. The distance between the PVC fogging pipe and the bottom plate in the box is 2 cm, and the distance between the PVC salt water pipe in the box and the bottom plate is 3 cm. The distance between the opening of the liquid level switch and the bottom of the tank is 10.5 centimeters. The distance between the opening of the heating tube and the bottom of the tank is 7.5 centimeters. The distance between the sensor opening and the bottom of the tank is 21.5 centimeters. At the same time, there must be a pressure balance hole when adding salt water in the tank.

5, sample rack must be complete.

6. The lid must be fully sealed.

7. The rubber stopper of the mist collector to the connection between the triangle funnel and the box must be tight. The fog tube must not be too long. There must be at most 15 cm of headroom.

8. The entire exterior of the box must be free of scratches.

9, cover must be able to switch freely. The distance between the cover and the sides of the sides of the sink must be within 3 mm.

10, the control panel must be clear, no scratches on the surface.

11, saturator surface planing must be beautiful.

12, the entire box can not exist leaking phenomenon.

13. All the screws used on the salt spray box must be made of stainless steel and the screw used must not be more than 5 mm above the screw cap after the nut is screwed on.

14. The saturator drain valve must be installed so that it can switch horizontally.
