How do I read the mercury thermometer?
Quick Tips for Reading a Mercury Thermometer
- Hold thermometer between your finger and thumb near the glass top (called the expansion chamber), opposite the spherical base where the silver tip is located.
- Shake it down. With a flick of your wrist, shake thermometer in a downward motion, toward the spherical base, so the mercury can settle before measurement begins. This is especially important prior to first use.
- Place thermometer in the designated area. Keep in mind that it may take 2-4 minutes to read the proper temperature when using a mercury thermometer. *Note: Although thermometer arrives sterilized, be sure to clean before each use.
- Remove thermometer and look for the temperature (°C or °F) in the scale lines etched along the capillary tube.
- How to locate the mercury: Look for the bubble above the silver tip. As you rotate the thermometer, the thin line that travels from the spherical base through the capillary tube gradually becomes visible. Rotate until you can see the mercury line.
