The REVCO RCRF252A14, manufactured by Thermo Fisher Scientific, is an advanced environmental chamber that offers precise control over temperature, relative humidity, and light levels. This chamber is specifically designed to replicate a wide range of indoor and outdoor environmental conditions, enabling comprehensive testing and research of various products. Operating within a temperature range of -20°C to +70°C, the chamber ensures exceptional accuracy of +/- 0.2°C and uniformity of 0.6°C. Equipped with specialized fans, it maintains consistent and homogeneous conditions throughout the entire chamber, enabling uniform environmental conditions for diverse testing requirements. The humidity control feature allows adjustment from 5% to 95% with an accuracy of +/- 3% RH and uniformity of 5%. The chamber also includes illumination testing tools, featuring a standard bank of four fluorescent lamps that provide temperature-controlled lighting ranging from 400 to 8,000 lux at a distance of 380 to 970 mm from the product. Moreover, additional lamp supports, such as UV and Daylight lamp holders, can be incorporated as needed. Safety is prioritized with a comprehensive range of alarms and safety devices, including over-temperature and low-temperature alarms, ensuring prompt notification if the chamber deviates from specified temperature parameters. Unauthorized access is prevented through a lock feature, and the system can be programmed to record temperature changes. Overall, the REVCO RCRF252A14 environmental chamber is a dependable and precise laboratory instrument, offering controlled and accurate environmental conditions for meticulous product testing across a wide range of materials and scenarios.
