Digital vs Traditional Glass Thermometer - Accuracy, Safety & Usage Guide #1852072 (License: Personal Use)

This high-resolution image shows a traditional mercury-in-glass clinical thermometer with a clear scale marked in Celsius (35-42°C), a red fever indicator at 38°C, and a yellow-colored mercury column indicating 37.5°C. The bulb end is metallic for rapid heat conduction, and the capillary tube ensures precise measurement via thermal expansion. Though largely replaced by digital devices, such thermometers remain valued in certain medical and educational contexts for their reliability and calibration stability.

Used on health education pages, medical equipment comparison articles, or pediatric care guides where users seek clarity on thermometer types, safety, and interpretation of readings. Matches intent for understanding fever thresholds, historical medical tools, or validating home measurements.
