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 the cooler and fan installed in the test chamber. During the "immersion" cycle, constant temperature water from the 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 through "natural drop," reducing power consumption for circulation, making it an energy-efficient design. 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.

This is a device that measures changes in soil along a vertical line using a manual loading method and investigates the strength of the ground. The obtained cone index [qc] is used to determine vehicle mobility (trafficability) and the softness of the ground. The measurement method involves manually driving a cone tip vertically into the soil (at a speed of about 1 cm/sec), reading the dial gauge value each time the 10 cm spaced markings on the rod penetrate the surface, and calculating the penetration resistance. This penetration resistance is divided by the cone cross-sectional area to determine the relative strength of the ground.

The amount of air and the bubble spacing coefficient obtained from the bubble structure meter of hardened concrete are important indicators of resistance to freeze-thaw cycles. The measurement methods include the "Linear Traverse Method" and the "Modified Point Count Method" specified by ASTM, but both 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. By filling the bubbles in the concrete sample with cyanoacrylate containing fluorescent dye and then irradiating the sample with ultraviolet light, only the bubble structure emits light. At the same time, by binarizing the brightness at a certain threshold, image processing became possible. The operation and handling are also simple, allowing for easier and faster measurement of bubble structures than before.

Until now, conventional constant temperature water circulation devices had their operation and measurement panels located outside the main unit, making it difficult to notice equipment troubles or abnormal water temperatures. Additionally, it was necessary to go outside to set the operating parameters. Marui's new constant temperature water circulation device is designed to separate the controller from the main unit, allowing it to be installed indoors. This enables management of operations within the testing room, and the equipped alarm buzzer and abnormal lamp allow for quick detection of any potential issues. Furthermore, temperature control and circulation of the conditioning tank are carried out using a "heat exchange tank" that is separated from the main unit, preventing the clogging of equipment piping with calcium carbonate as seen in conventional systems. Additionally, features have been added to reduce the adhesion of calcium carbonate to the heat exchange coils and circulation pumps, thereby minimizing the effort required for coil cleaning and enhancing usability.
