first aid thermometer

Many models offer multiple modes: ear and forehead (non-contact) readings; oral, rectal, and underarm for baby and adult checks; and some units include dedicated bottle/food and room-temperature modes.

Read times vary by type: infrared ear/forehead models typically report in 1–2 seconds (often marketed as instant), contact oral/underarm/rectal models are around 8 seconds, and basal thermometers take longer (about 90 seconds).

Common power sources include coin cell batteries (CR1220, CR2032, CR1632) or AAA/AA alkaline batteries (1–2 AAA or 2 AA), depending on the model. Check the product specifications for the correct battery type.

Care recommendations vary by model. Most list wiping or spot cleaning the unit and probe; some models are described as waterproof and allow rinsing of specific parts. Follow the manufacturer's cleaning instructions in the manual and use only recommended methods and solutions.

Memory features vary: some units recall only the last reading, while others store multiple past readings—common capacities include 19, 30, or up to 50 saved records—to help track temperature trends over time.

Common inclusions are batteries and instruction manuals. Some models also include protective cases, lens or probe covers, protective caps, and small storage pouches or guides.
