Freeze-thaw cabinets are applied for evaluation of the stability of concrete and building material as to exposure to freeze-thaw changes. Based on the degree of weathering, the durability can be determined. RUMED® freeze-thaw 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.
