UV Testing Machine ~ Programmable UV Weather Resistance Test Equipment - LRHS-10UVN

UV weather resistance test chamber

Dimension Comparison

Purpose
This series is applicable for the sunlight resistant test of nonmetallic materials and aging test of artificial light sources.
Chamber Structure

Standard configuration of test chamber

Eight UV lamps are installed on two sides of the working room.

Quantity of fixture of sample shelf: 20 blocks

Dimension of fixture of sample shelf: 404×105 (mm)

It introduces the heating method through internal bladder water tank with fast heating speed and even temperature distribution.

Drainage system introduces the vortex-type and U-type deposition device.

The sample surface is parallel to and 50mm far away from the surface of UV lamp

Test specimen and the shelf constitute the trapezidal inner wall of the chamber.

Chamber cover introduces the two-way flip type for easy opening and closing.

Light source

3.5.1 Eight UV fluorescent lamps of rated power of 40W as light source. The lamps are installed on two sides of the machine equally. UVA-340 and UVB-313 light sources are available for selection (optional).

3.5.2 The spectral energy distribution of UVA-340 lamp focus on wavelength of 340nm.

3.5.3 The spectral energy distribution of UVB-313 lamp focus on wavelength of 313nm.

3.5.4 Since the light energy output of fluorescent lamp decrease with time, in order to reduce impact of decreasing light energy on the test, the test chamber introduces the design that a new lamp shall replace an old lamp after 1/4 service life of the lamp, in this way, the UV light source shall always include new lamps and old lamps so that constant light energy output shall be realized;

3.5.5 All lamps are imported from America with active service life of 1600~1800 hours, and the service life of 2500 hours may be achieved by irradiation adjustment.
