Description

Technical Field

[0001] This utility model relates to the field of temperature regulation and control technology, specifically to a small, visual, automatic temperature-regulating and temperature-controlled air bath. Background Technology

[0002] In the testing of petroleum products, it is necessary to test their performance at different temperature points. Therefore, an adjustable and constant temperature system is required, and the temperature difference between different locations within the system should be small, ideally uniform.

[0003] Currently, in the oil testing industry, air baths with an adjustable temperature range of 30℃-100℃ have a single-point temperature control accuracy of approximately ±0.5℃, and a bath temperature control accuracy of ±3℃. However, in actual use, the temperature control accuracy and system temperature difference will be even greater.

[0004] Therefore, most tests use liquid baths such as water baths. However, due to the adverse effects of liquids evaporating and producing odors at high temperatures, requiring regular addition and replacement, there is an increasing demand for air baths in testing. However, the low temperature control accuracy of air baths and the large temperature difference between different locations affect the test results and need to be addressed urgently.
