Design and manufacture of material testing instrumentation including a wide range of instruments and systems that simulate the environmental parameters of sunlight, temperature and moisture in the form of rain, dew and humidity. These parameters are controlled to replicate actual end use conditions. The chambers incorporate light sources ranging from carbon arc to xenon; metal halide to fluorescent lamps. Typical applications can be found in a variety of industries: textiles, automotive, paints and coatings, plastics and polymers, paper, chemicals and pharmaceuticals.
