（China）YY-90 Salt Spray Tester -Touch-screen

Short Description:

I.Use:

Salt spray tester machine is mainly used for surface treatment of various materials, including paint. Electroplating. Inorganic and coated, anodized. After anti-rust oil and other anti-corrosion treatment, the corrosion resistance of its products is tested.

II.Features:

1. Imported digital display controller full digital circuit design, accurate temperature control, long service life, complete testing functions;

2. When working, the display interface is dynamic display, and there is a buzzer alarm to remind the working status; The instrument adopts ergonomic technology, easy to operate, more user-friendly;

3. With automatic/manual water adding system, when the water level is insufficient, it can automatically replenish the water level function, and the test is not interrupted;

4. Temperature controller using touch screen LCD display, PID control error ± 01.C;

5. Double overtemperature protection, insufficient water level warning to ensure safe use.

6. The laboratory adopts the direct steam heating method, the heating rate is fast and uniform, and the standby time is reduced.

7. The precision glass nozzle is evenly diffused by the conical disperser of the spray tower with adjustable fog and fog volume, and naturally falls on the test card, and ensures that there is no crystallization salt blockage.

IV.Technical Parameters:

4.1 Studio size: 90L (600*450*400mm)

Outer size: W1230*D780*H1150mm

4.2 Power Supply: 220V

4.3 Chamber material:

a. The testing machine chamber is made of light gray PVC plate with a thickness of 5mm

b. The seal of the laboratory cover is made of transparent acrylic impact resistant plate with a thickness of 5mm. Double layer thickening inside and outside the edge to prevent distortion due to long-term high temperature.

c. Hidden integrated test refill bottle, easy to clean, easy to operate.

d. The pressure air barrel adopts stainless steel high pressure barrel with the best insulation effect.

e. The test sample rack adopts the plane division type, the Angle can be adjusted arbitrarily, the fog is uniform on all sides, the fog is completely consistent, the test results are accurate, and the number of test samples is placed.

4.4 Saline spray test; NSS, ACSS

Laboratory: 35℃±1℃.

Pressure air barrel: 47℃±1℃.

4.5 Corrosion resistance test: CASS

Laboratory: 35℃±1℃.

4.6 Air supply system: Adjust the air pressure to 1Kg/cm2 in two stages. The first section is slightly adjusted 2Kg/cm2, using imported air filter, with drainage function. The second stage is precisely adjusted 1Kg/cm2, 1/4 pressure gauge, precision and accurate display.

4.7 Spray method:

a. Bernaut principle absorb brine and then atomize, atomization degree is uniform, no blocking crystallization phenomenon, can ensure continuous testing.

b. The nozzle is made of tempered glass, which can adjust the spray amount and spray Angle.

c. The spray volume is adjustable from 1 to 2ml/h (ml/80cm2/h standard requires 16 hours of testing for the average amount). The measuring cylinder adopts built-in installation, beautiful appearance, easy operation and observation, and reduces the installation space of the instrument.

4.8 Heating system: The direct heating method is adopted, the heating speed is fast, and the standby time is reduced. When the temperature reaches, the constant temperature state is automatically changed, the temperature is accurate, and the power consumption is low. Pure titanium heat pipe, acid and alkali corrosion resistance, long service life.

4.9 Control System:

The laboratory heating tank adopts liquid expansion safety temperature controller 0~120℃ (Italy EGO). The manual water adding system is used to manually supplement the pressure barrel and the water level of the laboratory to prevent the damage of the instrument from ultra-high temperature without water.

4.10 Fog removal system: Remove the salt spray in the test chamber during shutdown to prevent corrosion gas from flowing out and damaging other precision instruments in the laboratory.

4.11 Safety protection Device:

a. When the water level is low, the power supply is automatically cut off, and the safety warning light device is dynamically displayed.

b. Over temperature, automatically cut off the heater power supply, safety warning light device dynamic display.

c. When the water level of the test drug (salt water) is low, the safety warning light device is dynamically displayed.

e. Leakage protection function to prevent personal injury and instrument failure caused by line leakage or short circuit.
