Luminous Afterglow Performance Tester

The luminous afterglow performance tester is suitable for testing the luminous afterglow performance of various textiles. Fibers, yarns, and powders can all be tested.

Testing Principle

Use the specified light source as the excitation light source. Under the specified illuminance conditions, directly irradiate the sample. After the sample is excited to saturation, remove the excitation light source, and measure the afterglow brightness and decay time on the sample surface through a brightness meter.

Instrument Features

1. Automatically record the brightness value within the set time through software. Fully automatic measurement, simple operation, capable of long-time measurement, and automatically save data.
2. Multiple light-shielding designs in the fully enclosed test chamber reduce the influence of external light sources on test results.
3. Automatically switch test samples. One set of samples can be tested at a time for 3 groups.
4. Specially made imported sensors with fast sampling speed and high accuracy.
5. Wide testing range, covering powders, fibers, yarns, fabrics, etc.
