The history of Suga Test Instruments is the history of weather meters. Since 1958, Suga Test Instruments has been taking part in conferences for international standards such as ISO, JIS, ASTM, AATCC, CIE and IEC. Our weathering tests are in correlation with ISO and other international standards (ISO4892-2, SAE J2527, ASTM G155, etc.).
GX75 is designed to artificially reproduce outdoor and indoor deterioration factors such as sunlight, high and low temperatures, rainfall and dew. It exposes materials to these factors and accelerates the deterioration process to predict their lifespan in a relatively short period of time.
The weathering technology demanded by Japanese automotive manufactures and customers from many different industrial fields have established an incomparable xenon long life irradiation system and a direct specimen-surface irradiance-temperature control system.
1. 7.5kW high-rated power lamp and φ60mm outer filter keep arc wattage fluctuation and irradiance in infrared range to a minimum, and allow for approximately 2500 hours of use at 60 W/m2 (300 to 400nm).
2. The 180 mm distance between the electrodes inside the xenon lamp is designed to allow highly even distribution of irradiance to all the specimens.
3. The combination of the inner and outer filters accurately simulates the spectral irradiance distribution of both indoor and outdoor sunlight. The spectral power distribution is in total conformance with daylight filters and window glass filters specified in ISO, ASTM, SAE and JIS.
4. The Suga-developed filters for xenon lamps have a very minimal solarization, making them capable of approximately 2500 hours of use. The lamp and the filters can be replaced simultaneously (excluding certain filters).
The lamp including its electrodes is produced in-house, making the lamp and the instrument a perfect match.
