More than 100000 tests
All passed 80℃ environment temperature,long working full load test
The brightness and contrast were tested at 55℃ and minus 30℃.
Continuous tests at 35% current increase,ensure that brightness does not decay after several years of use.
All the machines have been through constant temperature and humidity,temperature 40 degrees,relative humidity 95% extreme environment,refrigeration continuous normal operation simulation test.
The corrosion resistance and antioxidant properties of metal materials in salt fog chamber have been tested to ensure that they do not rust for 20 years.
Passed long-time working and full load test,electrical safety morning of grounding resistance,insulation resistance and other rigorous testing.
All models are transported 50 km/h in rural highway and w100 km/h in highway to ensure that parts are not loose.
Over 1000000 press tests.
20000 tests,assuming delivered 2 times per day,the service life is guaranteed for more than 20 years.
