Forced-ageing test cabinets are applied in quality control for simulation of the ageing process of beer by cyclic temperature alternation. Based on the degree of cloudiness, the shelf-life of the beer can be determined by calculation. RUMED® forced-ageing test cabinets are equipped with reinforced supporting shelves and effect a uniform temperature distribution in space. RUMED® applies a powerful, low-noise and eco-friendly compressor technology and predominantly natural refrigerants for cooling. The program-controlled temperature variations, the number of cycles and their documentation are realized with the intuitively operated Control2015touch. Due to the USB and Ethernet interface, external data evaluation is possible. The reference temperature of a sample can be documented by means of the optional product sensor.
