GY908B Standard Light Source Box (Touchscreen)

Description

Product Introduction:

It is used for assessing color fastness in textiles, printing and dyeing, apparel, leather, and other products, as well as for evaluating metamerism—color differences under different lighting conditions.

Applicable Standard:

ASTM D1729, ISO 3668, FZ/T 01047, BS 950, DIN 6173, and other standards

Product Features:

1. Equipped with a touch-screen control system.

2. The touchscreen features automatic timing, recording the first illumination time and the total operating time for each lamp tube, promptly alerting users to the lamp’s usage status and ensuring the accuracy of color‑matching light sources.

3. Utilizing a new high‑efficiency optical technology, the device is ready to use immediately, eliminating the need for lengthy warm‑up periods and preventing flickering caused by induced currents, thereby ensuring fast and reliable color evaluation.

4. Equipped with imported lamp tubes and electronic ballasts, ensuring stable and precise illumination levels, and featuring overvoltage and overcurrent protection.

5. Employing automatic compensation technology, the lamp consumes less power and boasts high luminous efficiency.

6. Configure various special light sources according to user requirements;

7. Switch freely between Chinese and English;

8. Compact cabinet size, convenient to use;

Standard light source color temperature:

1. D65 6500K: An international standard for the textile, automotive, retail, plastics, paint, and printing industries.

2. F light source, 2300–2800 K: suitable for residential or storefront lighting; when used in conjunction with other light sources, it can be employed to detect metamerism.

3. CWF 4150K: Typical U.S. office and storefront lighting

4. TL84 4000K: Typical lighting for offices and shops in the Eurasian region

5. TL83 3000K – Typical lighting for offices and shop windows

6. UVB ultraviolet light source
