Hi,
We have a project to design an electronic meter device which needs to be waterproof IP67. The mechanical engineers have design the casing but we need to ensure the finished product is IP67. The device has a LCD display and the dimensions are about 220x95x35 mm .
We intend to have a waterproof test for each meter. Can anyone help with an idea of how can we check that after the test there is no water inside the meter?
If there is a lot of water we can see on the lens that is in front of the LCD display but how can we know if there are only a couple of water drops? We cannot open the meter!
Someone came with the idea to centrifuge the meter so that the water is forced to go on the lens. Another was to heat the meter until the lens become flushing (hope flushing is the right word ).
Have anyone done this?
Thanks,
Cristi
