ISO20653 High Temperature And Pressure Water Jet Test Chamber IPX9K
This device is applied to electrical and electronics, electric
appliances, auto parts and other accessories enclosure and sealing
elements under the condition of high temperature and high pressure
and high flow of water, the ability of its enclosure to prevent
water penetration. This machine is designed and manufactured
accordance with the test requirement of latest version standard
ISO20653(High temperature and high pressure water jet test).
The internal and external material is made of high quality 304
stainless steel. With large observation glass window and elegant
appearance. The turntable and spray rod uses high quality motor.
The revolving speed can be adjustable as per use’s requirement. And
with a good safety protection function.
