The development of modern technology has greatly improved the technology of the salt spray test chamber. What are the characteristics of the overall design of the current salt spray test chamber? 1. The whole salt spray test chamber is made of PVC board. The advanced three-dimensional reinforcement technology is adopted in the interior, the structure is strong, never deformed, and it is resistant to acid and alkali, high temperature and never aging. It is suitable for salt spray and copper acetate. And other test specifications. 2. The controller is easy to operate on the same panel, and it is clear at a glance. 3. The automatic / manual water adding system is adopted, which has the function of automatically replenishing the water level when the water level is insufficient, and the test is not interrupted. Low water level warning ensures safe use. 4. The precision glass nozzle (PYREX) is made of special glass. The mist diffuses evenly and falls naturally on the test piece. It is used continuously for 4000 hours and ensures no crystalline salt blockage. Five, with double over-temperature protection function, warning display when over-temperature, and cut off the heater power to ensure safe use. 6. The imported temperature controller uses digital display and PID control with an error of ± 0.1 ℃. 7. The laboratory adopts direct steam heating method, the heating speed is fast and uniform, and the standby time is reduced. The heating tube is made of highly corrosion-resistant titanium tube.
