Features

Intelligent Touchscreen Control Panel

Microcomputer control system for enhanced efficiency and reliability. Programmable 7-inch colour LCD touchscreen

enables diverse functions including control, detection, calculation, and data display.

Robust Software Capabilities

Enhanced control system handles complex customised programmes and straightforward pre-programmed tests.

Operating interface features intuitive icons for clear comprehension; programmable stepwise adjustments for irradiance, temperature, and humidity

accommodate diverse testing requirements.

Multi-faceted Protection Design

The instrument incorporates current/voltage monitoring, water quality surveillance, temperature monitoring, water flow monitoring, low-water alerts,

over-temperature protection, and leakage current safeguards to ensure equipment and personnel safety.

Extensive Testing Area

Featuring imported ultraviolet lamps and a spacious experimental chamber, it accommodates up to 48 sample holders simultaneously,

enhancing uniform exposure consistency across all specimens.

Test Principle

The UV-master Ultraviolet Aging Test Chamber performs accelerated aging tests by simulating ultraviolet radiation, temperature, and humidity conditions found in natural environments.

High-intensity ultraviolet light sources irradiate the samples while temperature and humidity are precisely controlled, simulating long-term exposure conditions.

During the test, chemical reactions occur on the sample surface, leading to aging phenomena such as discoloration, embrittlement, and degradation.

The test results provide data on photo-aging behavior and weather resistance of materials under actual service conditions, enabling evaluation of material service life and reliability.

Operating Instructions

Sample Installation:

Secure the samples onto the test holders and ensure the sample surfaces are flat and properly positioned.

Test Parameter Setting:

Set irradiance, temperature, humidity, and spray time according to test requirements.

Test Start:

Start the equipment; the automatic control system initiates the ultraviolet aging test according to the preset parameters.

Test Monitoring:

Observe the aging condition of the samples during testing and record irradiance, temperature, and humidity data in real time.

Test Completion:

After completion of the test, stop the equipment and remove the samples for subsequent analysis.
