Model：HK-NC-800
Application of dustproof test box:
The dust-proof test box is used to conduct dust-proof test on mobile phone electrical, electronic, automobile, motorcycle accessories and other product parts. Comply with iec-529 gb4280-93 sand dust test method (dust test), gb2423.37-89 sand dust test method (dust test), gb10485 dust test method and equivalent JIS, DIN, min and other test standards,
Structure and material of dustproof test box: material of inner box: SUS201 stainless steel plate, material of outer box: A3 plate spray plastic powder, with large observation window on the door, unique air duct design, to ensure that the box produces non layered vertical circulation air,
Technical parameters of dustproof test box:
1. Test area dimension D * w * H (mm): 1000 * 1000 * 1000 / 800 * 800 * 800
2. Rated voltage: 220V ± 10%, 50Hz
3. Height adjustment range of sample grid: 0 ~ 750mm
4. Timing range: 0-99 hours and 59 minutes
5. Timing accuracy: ± 1 minute
6. Load cycle control: 0-99 hours 59 minutes
7. Dust blowing cycle control: 1s ~ 9999 minutes (i.e. sand spraying time 1s ~ 9999s and 1s ~ 9999 minutes can be set freely)
8. Amount of test sand (or talcum powder): 2kg / m3-4kg / m3
9. Specification of test sand (or talcum powder): dry talcum powder that can pass the square hole sieve with the mesh diameter of 75um and the wire diameter of 50um.
10. Shell material: stainless steel liner, shell electrostatic spray plastic or stainless steel
11. Temperature range: 15-35 ℃ (natural temperature) not controlled, determined by the customer's Laboratory
12. Humidity range: 45-75% HR (natural humidity) is not controlled, which is determined by the customer's laboratory. For example, if dust moisture returns, it can be solved by heating.

1. PLC touch screen control (independent R & D controller)
2. PT100 test sensor (for sand dust baking)
3. Safety protection device
4. Instrument over temperature protection function
5. Power supply phase loss protection
6. Leakage circuit breaker
7. Power supply: AC 220 V 50Hz
8. Window: toughened glass window 800X800 / 1000X1000mm
9. (optional) vacuum pumping: one vacuum pump, air flow meter, pressure gauge, dust filter.
