Product Name: Salt Dry Wet Composite Corrosion Testing Machine
Model: HY-SS-PRO
This machine complies with specifications such as IS, JASO M609 M610, SAE-J234, ASTM, etc.

Specification Description:
1、 Experimental space SS: 60.901.20160
2、 Outer box space: according to actual size
3、 Power supply: 220V 3 µ 50/60HZ MAX 20A
4、 Material:
(A) The laboratory uses imported PVC boards that are acid and alkali resistant.
(B) The outer box is made of imported PVC board, which is acid and alkali resistant.
(C) The reagent replenishment water tank adopts a hidden water level gauge, which is easy to clean and not easy to break.
(D) The saturated air tank adopts SUS # 304 stainless steel high-pressure tank for insulation effect.

5、 According to customer testing requirements, a salt dry wet composite test can be set up
Salt spray test - humidity test - water spray test
(A) Salt water spray laboratory: NSS, CASS
(1) Laboratory: 35 ℃～ 50 ℃± 1 ℃
(2) Saturated air tank: 47 ℃± 1 ℃
(3) Test time 2 hours
(B) Wetting test:
(1) Temperature: 40 ℃± 2 ℃
(2) Humidity: above 93%
(3) Time: 22H
(C) Spray test:
(1) Water flow rate: 800~1600L/H
6、 Air supply system:
The air pressure is adjusted in two stages at 1kg/cm2. The first is that the inlet pressure regulating filter is equipped with a water filtration function,
Roughly adjust to 2-2.5kg/cm2, the second is the imported precision pressure regulating valve, adjust to a pressure gauge of 1kg/cm2.


7、 Spray mode:
1. Adopting the Bernoulli principle to extract and atomize saline water, the atomization degree is uniform and there is no blocking crystallization phenomenon, ensuring the standard of continuous testing.
2. Nozzle: made of special glass nozzle, which can adjust the size of spray volume and spray angle.
3. spray volume: adjustable 1.5 ± 0.5 ml 80cm2/Hr (16 hour average volume).
4.40L large brine liquid storage tank can be used for 48HR continuous spray.
8、 Heating system:
Using steam heating method, the heating speed is fast, reducing standby time, and the component damage rate is low.
Using S.S.R to control heating power, precise temperature, and low power consumption. (The electric heating tube is made of titanium alloy anti-corrosion tube)
9、 Circuit control system:
The main controller adopts a 7-inch LCD human-machine interface, and the main screen can plan the test program.
2. Fixed conditions can be set with a time range of 0-530 hours and 59 minutes.
3. The program mode can simultaneously set salt spray, moisture test, and water spray test
4. Equipped with a power-off memory device, the remaining programs can continue to be executed when the power is restored.
5. The temperature and humidity sensors adopt DIN PT-100 Ω (platinum sensing).

10、 Inlet and outlet system:
The water inlet adopts an automatic water replenishment system, which automatically replenishes when the water level is too low, and manual water replenishment can be used.
Drainage adopts acid and alkali resistant and corrosion-resistant pumping pumps to increase service life and reduce waiting time for drainage.
All pipeline accessories are imported with acid, alkali, and corrosion-resistant components, ensuring a long service life.

11、 Humidification system:
1. Adopt electronic bit mode P.I.D micro humidification system.
2. Equipped with dual protection devices for overheating and overflow.
3. The humidification and dehumidification systems are completely independent.
4. High polymer floating ball water valve is used for water level control.
5. Fully automatic humidification water replenishment device. (The machine needs to be connected to a water source)

12、 Safety protection device:
1. Equipped with a leakage power-off type non fuse protection switch.
2. Low water level protection switch.
3. Low salt solution protection switch
4. Double over temperature protection device to prevent mechanical or electronic actions from losing control.
5. Chinese indication screen for fault points.
