Room Temperature (Air-Cooled) Light Fastness Tester GT-D02A-1

Light Fastness Tester (Air-Cooled) GT-D02A-1

• The 2500W long arc xenon lamp is used to simulate the solar spectrum.
• Xenon Light Fastness Tester: High transmittance of filter combinations and use 95% of the transmittance filters and filter cartridges. With Low power consumption but achieve the same irradiation light requirements. To make the machine is more energy saving and environment friendly.
• Standard equipped with 420nm wave band, irradiance digital setting, real time monitoring,  closed loop automatic regulation, providing the most stable irradiance test light source for different standards (340nm, 420nm, 300-400nm and 300-800nm band optional ).
• Light fastness tester Test and radio transmission are powered by using light conversion technology, no additional power supply is required.
• The sample is tested with black plate thermometer (BPT), black plate standard thermometer (BST), irradiance detector at the same position (in equidistance) to really indicate measuring state of the sample, the tested data is transmitted synchronously by using technolody of radio frequency.
• Light Fastness Testing Machine With industrial temperature control (refrigeration) system for smoothly and fast adjusting temperature in test chamber.
• With several modes of operation (spray, alternating light and dark, revolution), can simulate the real climate state.
• Individual timing of each sample clamp may enable different sample test in a same tester and facilitate test monitor and reduce operation cost.
• 7-inch color touch screen, various test monitor models(animation, figure and chart), simply operate, directly and clear.
• 1000 hours of continuous operations.
• Industrial grade microcontroller with strong antijamming capability.
• can set and inquire the irradiation energy.
• The machine possess fault prompt functions and self-diagnostic function.

Q: What is the lifespan of the 2500W Xenon lamp?

The lamp typically lasts for approximately 1,500 hours under standard ISO 105 B02 conditions. The system features an automatic irradiance compensation to maintain stability as the lamp ages.

Q: Can this machine test multiple standards simultaneously?

Yes. Each sample holder features an individual timer, allowing you to monitor different specimens independently and reduce overall operation costs.

Q: Does it require an external water cooling system?

No, the GT-D02A-1 is an air-cooled model. It uses an industrial refrigeration system to control chamber temperature, making it more portable and easier to maintain than water-cooled alternatives.

Pro Tip: For high-volume research requiring faster acceleration and full weather simulation (Rain/UV/Moisture) per ASTM G155, explore our [Water-Cooled Xenon Weatherometer GT-3000]—the professional upgrade to standard light fastness testing.

Q: How is the irradiance monitored and calibrated?

It uses a high-precision irradiance detector and radio frequency technology for data transmission. Irradiance is controlled via a closed-loop system (standard 420nm, with 340nm or other bands optional).
