Thermometers: Clinical vs Laboratory

The video tutorial introduces thermometers, explaining their purpose and history. It covers two main types: clinical and laboratory thermometers. Clinical thermometers are used for measuring human body temperature and include digital, glass and mercury, and electronic ear thermometers. Laboratory thermometers are used for scientific purposes and include liquid-in-glass, bimetallic strip, and infrared thermometers. The video highlights similarities and differences between the two types, focusing on range, accuracy, and usage. It concludes with a brief mention of future informative videos.
