Description

Technical Field

[0001] The utility model relates to the technical field of moisture detection equipment, in particular to a polyurethane foam composition moisture meter. Background Art

[0002] The Halogen Rapid Moisture Meter is a new, rapid moisture detection instrument. Compared to the international oven heating method, its test results are highly consistent, offering a viable alternative and significantly higher efficiency than the oven heating method. Typical samples can be tested in just a few minutes. The instrument is easy to operate and offers accurate testing. Its red digital display provides a clear and visible indication of moisture content, initial and final sample values, measurement time, and initial and final temperature values.

[0003] Existing devices, such as CN219015978U, are moisture analyzers comprising a ring-shaped halogen lamp and a weighing mechanism for weighing. The halogen lamp is used for heating, and further comprising a main body and a cover. The cover is hingedly connected to the main body, and the halogen lamp is disposed on the side of the cover facing the main body. The weighing mechanism is disposed within the main body, and a weighing pan is provided within the main body for placing the sample to be tested. The lower end of the weighing pan abuts the weighing mechanism, and the weighing pan is positioned opposite the halogen lamp. The weighing pan is slidably connected to the main body, and a handle is provided on the side wall of the weighing pan. The handle is covered with a rubber sleeve, and the main body has a sliding groove corresponding to the handle. The handle passes through the sliding groove and slides vertically along the sliding groove. The weighing mechanism compares the weight of the sample to be tested before and after heating to determine the moisture content. The handle is covered with a rubber sleeve with poor thermal conductivity. After opening the cover, the entire weighing pan can be removed by the handle to replace the sample to be tested, reducing the risk of burns.

[0004] In order to solve the problem of dust floating into the equipment when the moisture meter is not in use, the evaporation temperature of the moisture meter is higher when in use, so more heat dissipation holes are set. The heat dissipation holes will only work when the moisture meter is working. When the moisture meter is not in use, due to the large number of heat dissipation holes, dust is easily allowed to enter, affecting the accuracy of the moisture meter. This needs to be improved.
