A hot air oven works by using dry, heated air to provide controlled temperature conditions for laboratory testing. Heating elements warm the air inside the chamber, while a fan or natural circulation helps distribute heat evenly around the samples. The temperature is set according to the testing requirement and maintained for a specific period.

Hot air ovens are commonly used for drying, moisture removal, heat treatment, and sterilization of suitable laboratory materials. Before testing, samples are placed evenly inside the chamber without blocking air circulation. Once the required temperature and time are reached, the samples can be removed and evaluated.

For consistent results, proper temperature control, uniform air circulation, and regular calibration are important. Presto Stantest Pvt Ltd offers hot air ovens for reliable laboratory and industrial testing applications.
