benchtop uv accelerated weathering testers

Desk-type Compact UV Test Chamber China Supplier & Manufacturer

Different from the vertical type UV test chamber, Bench-top UV Accelerated Weathering Tester is characterized of a compact dimension which has no harsh requirement for test site. It is capable of creating an atmosphere full of aggregate ultraviolet at the specified temperature by means of 3 pcs UV light tubes as the light source to measure the weathering resistance of plastics, rubbers, films or other outdoor products. After the specimen is taken out from the chamber, the changes in gloss, intensity, powdering, cracking, blistering, fading are observed for judging the degree of damage to physical property.

Just same as all other artificial climate aging test equipment, the test results from the benchtop UV test chamber also can’t 100% replace the actual state in the sunlight for quite a long time, but it can provide a relatively reliable test result to evaluate the specimen performance, select and improve the material formula.

The core function parts consist of a UV source, water spray system and temperature control system.

There are two types of light tubes: UVA-340 & UVB-313, both of which are used to simulate the short wave ultraviolet. UVA-340 is a more frequently used UV source than UVB-313 because the ultraviolet emitted from UVB-313 is much too violent. UVB-313 can accelerate the weathering to the most degree, resulting in harm for some specimens during the test.

The spray system is designed to simulate the use environment more real, featuring an automatic stop after running for a preset period. Our UV accelerated weathering tester allows presetting the test temperature and keeping it constant throughout the test to expose the specimen to the given temperature to speed up the course of weathering.

Benchtop UV Accelerated Weathering Test Procedure

  1. Prepare the test pieces based on the relevant specifications and place them into the cabinet.
  2. Connect the water source to the inlet in the rear of the machine firmly, and a drain pipe also needs to be installed.
  3. Plug in and turn on the device, choose the language, and set the temperature, time and other necessary parameters.
  4. Click “Start” to actuate the instrument, and the machine will carry out the test according to the presetting until the test ends.
  5. After completing the test, water in the tank should be drained utterly, and the test area should be cleaned and dried for use next time.
