Parallel UV Weathering Test Chamber

1.2Model

UV340-P (Imported lamp from Q-lab,   USA)

2.Product overview and scope of   application

2.1 Overview

The   damage caused by sunlight and moisture to materials causes tens of thousands   of dollars in economic losses every year. The UV weathering test chamber can   reproduce the damage caused by sunlight and dew. The test chamber exposes the   material to be tested in a controlled interactive cycle of sunlight and   moisture while increasing the temperature. The test chamber uses ultraviolet   fluorescent lamps to simulate sunlight and simulates the effects of moisture   through condensation.

2.2 Scope of application

It is   suitable for testing various materials and inspecting the aging degree of   related products and materials under changes in climatic conditions such as   sunlight, temperature, humidity, condensation, etc.

3. Sample restrictions

This test equipment is prohibited from:

Testing and storing samples of flammable,   explosive, and volatile substances

Testing and storing samples of corrosive   substances

Testing or storing biological samples

Testing   and storing samples of strong electromagnetic radiation sources

6.Structural characteristics

6.1Chamber structure

The   chamber adopts an integrated structure, which is divided into three parts:   upper, middle and lower. The upper part is the control panel, the middle is   the test work area, and the lower part is the electrical and mechanical room.   The inner tank is made of 1.2mm SUS304 stainless steel plate, and the outer   shell is made of 1.2mm thick A3 steel plate sprayed with plastic. The bottom   of the equipment is equipped with a humidification system and a water storage   tank, and is equipped with a water heating and air heating system. The   circulation system consists of a fan and an air duct to increase the air flow   and greatly improve the temperature uniformity of the test chamber
