Environmental testing is a process of subjecting a product to different environmental conditions to assess its performance and quality under various scenarios. Laboratory temperature humidity test chambers are devices that control the temperature and relative humidity inside a chamber to simulate different climatic conditions for environmental testing. Laboratory temperature humidity test chambers are basic and essential equipment for environmental testing, as they can cover a wide range of temperature and humidity levels, from -70°C to +180°C and from 10% to 98% RH5. Laboratory temperature humidity test chambers can also perform various tests, such as stability tests, aging tests, corrosion tests, and accelerated life tests6. Laboratory temperature humidity test chambers are used for testing products such as pharmaceuticals, cosmetics, electronics, textiles, and food.
