Simple Tools to Practice Reading Thermometers

Reading a thermometer accurately is one of the first skills new healthcare students learn. Whether checking a patient's temperature at home or in a clinical setting, it's essential to understand how to read different thermometer types correctly.


These virtual practice tools let you explore and test your thermometer-reading skills using safe, interactive simulations. Ideal for students, instructors, and peer coaches, it’s a hands-on way to get familiar with single-use and mercury-free glass thermometers.


How the Virtual Thermometers Work

Instructions for learning through observation:

  1. Drag the slider to increase or decrease the temperature.

  2. Watch how the temperature indicators (lines or dots) change.

  3. Read the value based on the thermometer display.


To test your skills, follow these steps:

  1. Click HIDE ANSWER to cover the reading.

  2. Move the slider to a new position.

  3. Say the temperature out loud.

  4. Click SHOW ANSWER to check your accuracy.


💡 Tip: Use your browser's zoom tool for a closer look at the thermometer details.


Virtual Thermometers


Single-Use Disposable Thermometers

This virtual version simulates dot-style thermometers like Tempa-DOT® or NexTemp®. These are often used for oral and underarm (axillary) temperatures. The dots change color with heat to show the reading. Use this tool to practice interpreting the dotted indicators and recognizing temperature changes quickly and safely.

Type B



Mercury-Free Glass Thermometer (Fahrenheit and Celsius)

This tool models a classic, reusable glass thermometer without mercury. These are typically used for oral, rectal, or underarm readings. Watch the silver line rise and fall based on temperature and learn how to read it on both Fahrenheit and Celsius scales. Practice spotting the exact value where the line stops.
