Difference Between Laboratory Thermometer and Clinical Thermometer
Laboratory thermometers and clinical thermometers serve different purposes and are designed accordingly. Here’s a detailed comparison:
Purpose
- Laboratory thermometers are used in scientific experiments to measure the temperature of various substances, including liquids and gases.
- Clinical thermometers are specifically designed to measure human body temperature for medical diagnostics.
Temperature Range
- Laboratory thermometers typically have a wider temperature range, often from -10°C to 110°C or more, enabling them to measure extreme temperatures.
- Clinical thermometers usually measure a narrower range, typically from 35°C to 42°C, suitable for detecting fevers and other medical conditions.
Accuracy and Scale
- Laboratory thermometers are highly accurate and often come with finer scales for precise measurements.
- Clinical thermometers, while accurate for body temperatures, may not be as precise for measurements outside the normal human range.
Design and Features
- Laboratory thermometers are often more robust and made from materials like glass or metal, suitable for various environments.
- Clinical thermometers are designed for easy handling, often featuring a quick-read digital display or a glass design with a constricted neck to prevent quick temperature drop.
Usage Method
- Laboratory thermometers may require specific positioning and handling, depending on the experiment.
- Clinical thermometers are designed for straightforward use, often placed under the tongue, in the armpit, or rectally for accurate body temperature readings.
In summary, using a laboratory thermometer for body temperature measurement is impractical due to its design, temperature range, and intended purpose, making clinical thermometers the preferred choice for medical use.
