Product Description
This series of dustproof test equipment is specially provided for scientific research, product development and quality testing. Corresponding environmental simulation and accelerated testing tests are used to assess and determine the protection level of electrical and electronic product enclosures and seals and electrical equipment enclosures, as well as whether they can ensure good working performance and performance of equipment and components after the dustproof test or during the test. Tests for currently used (environmental durability of road vehicle exterior lighting and light signaling devices).
This equipment is developed and designed in accordance with the shell protection level standards. It is reasonable, simple to operate and easy to maintain. All indicators comply with national standards.
The safety, reliability and quality of product performance are directly related to the safety of users' lives and property. Dustproof test is an indispensable and important testing equipment. In order to further improve the safety performance and quality of products, the country has promulgated a series of relevant standards.

Introduction to structural design
This sand and dust test equipment uses high-quality materials and uses advanced processing equipment to process and shape the box and door outer wall materials. . The surface of the thick high-quality carbon steel plate is electrostatically sprayed and the color is white gray, beautiful and smooth. The colors are coordinated and the lines are smooth and natural. The inner tank is made of imported stainless steel plates.
Insulation cotton boards are filled between the inner and outer gallbladders of the equipment to ensure that the high test temperature will not be transmitted outside. The sample holder and other accessories in the room are all made of stainless steel plates, are reasonably designed and durable.
A set of lead holes are installed on the side of the box for communication purposes during testing. At the same time, there is a dustproof socket inside the laboratory to ensure that the test piece is powered on internally during the test to ensure the orderly conduct of the test.
Test hole dust-proof socket
The fan equipped with the equipment has an air flow that can circulate dust vertically to ensure that the test dust circulates in the room and the convection dust can be recycled according to the standard requirements
The equipment itself has good During the sealing performance test, the conditions of the indoor test can be clearly observed through the large glass observation window on the door. It is also equipped with a lighting system and a wiper. There is a device for replacing dust at the bottom of the equipment. The base is equipped with four movable casters for movement. convenient.
The equipment is equipped with a vacuum system to meet the needs of negative pressure vacuuming of the test piece during the test.
