The "Temperature Cycling Test Machine" for construction finishing materials adopts a "direct circulation method" that minimizes heat loss and ensures uniform temperature distribution. During the "cooling" cycle, stable cold air circulation is achieved by a cooler and fan installed in the test chamber. In the "immersion" cycle, constant temperature water from a water tank located at the bottom of the test chamber circulates, eliminating heat loss in the circulation path. Additionally, warm water returns to the water tank via "natural drop," resulting in an energy-saving design that reduces power consumption during circulation. It complies with JIS A 6909. *If you are considering a custom test, it is also possible to design and manufacture a dedicated testing machine! We will propose a testing machine that matches your company after discussions. 【Features】 ■ Large color touch panel (10 inches) for easy operation and settings! ■ The water tank lid opens from the top, making cleaning and maintenance inside the tank easy! ■ The "self-diagnosis function" ensures peace of mind during troubleshooting! ■ The "test time reservation function" allows for efficient test planning! *For more details, please contact us or download the catalog to view.

The amount of air and bubble spacing coefficient obtained from the bubble structure meter of hardened concrete is an important indicator of resistance to freeze-thaw cycles. The measurement methods include the "linear traverse method" and the "modified point count method" specified by ASTM, both of which require significant time and effort, and there is a problem of individual differences in measurements. The image processing analysis method developed using PCs to solve this issue had not yet established image recognition technology. To address these problems, Marui developed a unique bubble structure measurement device. After filling the bubbles in the concrete sample with cyanoacrylate containing fluorescent dye, the sample is irradiated with ultraviolet light to make only the bubble structure emit light, while simultaneously enabling image processing by binarizing the brightness at a certain threshold. The operation and handling are also simple, allowing for easier and faster measurement of bubble structures than before.

The previous constant temperature water circulation devices had the operation and measurement panel located on the outdoor equipment body, making it difficult to notice equipment troubles or water temperature abnormalities. Additionally, it was necessary to go outside to set the operation. Marui's new constant temperature water circulation device is designed to separate the controller from the equipment body, allowing it to be installed indoors. This enables operation management within the testing room and allows for quick detection of any troubles through the equipped alarm buzzer and abnormality lamp. Furthermore, the temperature control and circulation of the conditioning tank are carried out by a "heat exchange tank" that is separated from the equipment body, preventing the clogging of calcium carbonate in the equipment piping as seen in conventional models. Additionally, features have been added to reduce the adhesion of calcium carbonate to the heat exchange coils and circulation pump, thereby minimizing the effort required for coil cleaning and enhancing usability.
