Constant Humidity Oven

Constant humidity ovens use heating elements to raise the temperature, while humidity sensors and humidifiers work together to control internal humidity, maintaining a constant temperature and humidity environment. They are used for sample drying, curing, aging tests, and are suitable for stability testing of materials such as coatings and paper.
Selection
When selecting, consider whether the temperature and humidity range and fluctuation match the sample requirements, the corrosion resistance of the chamber material, and the capacity to accommodate sample dimensions. Pay attention to humidity uniformity and control accuracy, ensure the operation interface is intuitive, and prioritize ease of maintenance and cleaning.

Temperature gradient control in high-temperature ovens during thermal resistance testing.
The heat resistance test simulates the performance of materials under high temperatures using a high-temperature oven, and the accuracy of its results is highly dependent on the uniformity of temperature inside the oven. If the temperature gradient is poorly controlled, it can lead to uneven heating of samples from the same batch, compromising the validity of the test.
What are the differences between a vacuum oven and a conventional oven?
The main difference between a vacuum oven and a conventional oven lies in their working pressure. Conventional ovens operate at atmospheric pressure, heating through air convection, making them suitable for routine drying tasks. In contrast, vacuum ovens are evacuated to low pressure to reduce air presence, primarily relying on thermal radiation for heat transfer. This makes them ideal for processing heat-sensitive, oxidation-prone materials or those requiring thorough drying.
