What is a metal halide lamp weather resistance test device (metal halide lamp weather meter)? It is a weather resistance test device that uses a metal halide lamp, a type of discharge lamp, as the light source.
Metal halide lamps emit about 20 to 30 times more UV rays than sunlight, and their acceleration factor is about 100 times that of sunlight and about 10 times that of xenon lamps.
Taking advantage of this excellent acceleration factor, they are mainly used in research and development departments.

This enables accurate and speedy weather resistance testing.

1. The acceleration rate is more than 10 times that of weather meters and fade meters. The efficiency of research and development, quality control, and process management of plastics, paints, inks, pigments, fibers, etc. is further improved. The uniform irradiation of high-intensity ultraviolet light allows for accurate and speedy weather resistance evaluation.
2. It is easy to check the ultraviolet irradiance. It is easy to use.
3. The irradiance distribution is uniform. Moreover, the output adjustment mechanism allows for free control of the ultraviolet irradiance.
4. Wavelengths below 295 nm are cut off. The adverse effects of wavelengths not found in sunlight have been eliminated.

What is a metal halide lamp?

Metal halide lamps have a light emitting tube filled with mercury, rare gases, and various metal halides, and emit a wide range of ultraviolet light from 200 to 450 nm.

The use of high-intensity ultraviolet light significantly speeds up weather resistance testing.

The strong deterioration power of ultraviolet light is concentrated and used.
The EYE Super UV Tester is a testing machine that enables weather resistance testing at an unprecedented speed.
The test time required for outdoor exposure, which took several months to several years, and for accelerated testing, which took hundreds to thousands of hours, has been significantly reduced, speeding up quality checks in research and development.

The cause of deterioration is ultraviolet light. That's why we applied ultraviolet light to weather resistance testing.

Ultraviolet light is the biggest cause of deterioration.
It further strengthens the deterioration acceleration caused by ultraviolet light, and also creates physical property changes similar to those caused by outdoor exposure and conventional weather meters.
This significantly speeds up weather resistance testing.
The EYE Super UV Tester, an ultra-accelerated weather resistance testing machine that goes far beyond conventional common sense, has been born.

The uniform irradiance distribution ensures the evaluation of weather resistance tests.

A specially designed reflector ensures uniform distribution of UV irradiance on the sample stage. Moreover, the use of an output adjustment mechanism ensures excellent uniformity with a constant irradiance. This highly reliable accelerated weather resistance tester has outstanding accuracy in accelerating deterioration.

The new UV irradiator has a new optical design that improves maintainability while maintaining the same testing performance.

The UV irradiation equipment has a newly designed optical equipment configuration, which has reduced the number of parts involved in lamp replacement, shortening work time and reducing replacement part costs. In the previous configuration, a filter was placed inside the water cooling jacket for the lamp, and this filter had to be replaced at the same time as the lamp, which was time-consuming and costly. The newly adopted optical filter is highly durable and hardly deteriorates due to heat or light during normal use. By adopting this filter and renewing the irradiation equipment, test results remained the same as before, and maintainability was improved.
