BOD Incubator Manufacturers in Ahmedabad Brand: Hema Humidity control is another important feature in BOD incubators, especially in tests that require stable moisture conditions for microbial growth. Ahmedabad manufacturers ensure that their BOD incubators include humidity control systems that maintain the ideal relative humidity levels, typically around 90%, for accurate results. This feature is critical for testing the oxygen demand in various water samples, where microbial activity can be significantly influenced by the surrounding humidity. The ability to precisely control both temperature and humidity makes these incubators highly reliable for environmental analysis.
