LBT611Q Sunlight and Climate Colorfastness Tester

Description

Product Introduction:

It is used for testing the lightfastness, weathering fastness, and photo‑aging performance of colored materials in textiles, printing and dyeing, apparel, automotive interior components, geotextiles, leather, engineered wood panels, wood flooring, plastics, and other applications. By precisely controlling parameters such as light irradiance, temperature, humidity, and rain exposure within the test chamber, it simulates natural environmental conditions to evaluate the lightfastness, weathering fastness, and photo‑aging resistance of test specimens. The system features online control of illumination intensity, automatic monitoring and compensation of light energy, closed-loop regulation of temperature and humidity, and multi‑point adjustment capabilities, including blackboard temperature control.

Reference standard:

GB/T 8427, GB/T 8430, GB/T 14576, GB/T 16422.2, 1865, 1189, GB/T 15102, GB/T 15104, AATCC 16, 169, ISO 105‑B02, ISO 105‑B04, ISO 105‑B06, ISO 4892‑2‑A, ISO 4892‑2‑BJIS 0843, GMW 3414, SAE J1960, 1885, JASO M346, PV1303, ASTM G155‑1, G155‑4, and others.

Product Features:

1. Complies with multiple national standards, including AATCC, ISO, GB/T, FZ/T, and BS.

2. Color touchscreen display with multiple visualization options—digital readouts, graphs, and more; capable of showing real-time monitoring curves for light irradiance, temperature, and humidity; and equipped with a library of pre‑set test standards for convenient selection and recall.

3. Safety‑protection monitoring points (irradiance, water level, cooling air flow, chamber temperature, chamber door, overcurrent, and overvoltage) enable the equipment to operate unattended.

4. Imported 3000W long-arc xenon lamp illumination system, accurately simulating the solar spectrum.

5. The irradiance sensor is fixed in position, eliminating measurement errors caused by rotational vibration of the turntable and light refraction as the sample holder rotates to different positions.

6. Automatic light energy compensation function.

7. Temperature (irradiation temperature, heater‑induced heating) and humidity (humidification via multiple ultrasonic atomizers and saturated steam humidification) dynamic equilibrium technology.

8. Precise and rapid control of BST and BPT.

9. Water circulation and water purification system.

10. Independent timing function for each sample.

11. Dual-loop electronic redundancy design ensures the instrument’s long-term continuous operation.
