Temperature and humidity cycling test machine for construction finishing materials [*Customizable options available*]
MIT-692-3-51/52 model
The direct circulation method maximally suppresses heat loss! Achieving testing with a stable temperature distribution.
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.

Applications/Examples of results
It can also be used for the "air-freezing water-thawing method" test in the "Test Method for Freeze-Thaw of Exterior Building Materials." As an application, "wet-dry cycling test" is also possible (optional). - JIS A 6909 "Finishing Coatings for Buildings - Temperature Cycle Test -" - JIS A 1435 "Test Method for Freeze-Thaw of Exterior Building Materials - Air-Freezing Water-Thawing Method -"
Detailed information
-
Design considering maintainability The motor for cold air circulation is external, making it less prone to troubles.
-
Space-saving types are also available. We have compact space-saving types that do not protrude in front of the aquarium.
-
The operation is easy to understand with a touch panel! You can easily manage operations and test conditions from the touch panel. In the event of any trouble, the abnormal areas, causes, and countermeasures will also be displayed on the touch panel, allowing you to address the issue immediately. It also automatically checks for leakage and displays the leakage points.
