4 mercury-free thermometers, glass thermometers

Glass Thermometer/Mercury-free Thermometer

The Glass Thermometer is a mercury-free thermometer that utilizes a special liquid alloy called Galinstan as the temperature-sensing liquid. This new alloy material is non-toxic, non-radioactive, and operates on the principle of thermal expansion and contraction.

Observation Method: By slowly rotating the thermometer, a dark gray line becomes visible, and the temperature reading is determined by the position of the top of the line.

The temperature-sensing liquid in the thermometer is made of Galinstan, a non-toxic and harmless liquid metal alloy that can be disposed of as regular household waste if broken.

The large-scale markings on the thermometer ensure more accurate readings, and the bold printing of the scale data makes it easier for the elderly to read.

Usage: Hold the upper end of the thermometer and swing the metal column down to below 35.5°C. For axillary measurement, dry the armpit and disinfect the thermometer with 75% alcohol. Place the temperature-sensing bulb of the thermometer at the top of the armpit and wait for 5 minutes before reading the temperature. During measurement, the armpit should be clamped tightly to prevent slipping, breakage, or inaccurate temperature measurement.

Understanding Medical Body Temperature Measurement and Celsius to Fahrenheit Conversion

Body Temperature Ranges:

Oral Temperature: Typically ranges from 35.5 to 37.4 degrees Celsius (95.9 to 99.3 degrees Fahrenheit).
Axillary Temperature: Generally falls between 35.0 to 37.0 degrees Celsius (95.0 to 98.6 degrees Fahrenheit).
Rectal Temperature: Typically varies between 36.2 to 37.9 degrees Celsius (97.2 to 100.2 degrees Fahrenheit).

Celsius to Fahrenheit Conversion:
To convert temperature from Celsius to Fahrenheit, use the formula:

Fahrenheit = (Celsius x 1.8) + 32
To convert temperature from Fahrenheit to Celsius, use the formula:

Celsius = (Fahrenheit – 32) ÷ 1.8
Understanding Celsius and Fahrenheit:
The Fahrenheit scale uses mercury as the measuring substance, with the freezing point of water set at 32 degrees Fahrenheit and the boiling point at 212 degrees Fahrenheit. On the other hand, the Celsius scale sets the temperature of a mixture of ice and water as 0 degrees Celsius, and the boiling point of water as 100 degrees Celsius.

By familiarizing yourself with these temperature ranges and knowing how to convert between Celsius and Fahrenheit, you can effectively interpret and compare temperature readings with ease.

Important Considerations for Temperature Measurement with Medical Thermometers

Accurate temperature measurement depends on the type of thermometer used, the measurement site, and the proper technique. Here are some important points to keep in mind:

Precautions before Measurement:
Before taking a temperature reading, ensure that the thermometer is undamaged, and if it contains a mercury column, swing it below 35°C. Failure to do so may lead to falsely elevated readings.

Prompt Reading of Results:
Once the thermometer is removed from the measurement site, promptly read and interpret the measurement results.

Proper Reading Technique:
When reading the thermometer’s numbers, hold it parallel to your line of sight and rotate it if necessary to ensure a clear view of the reading.

Oral Measurement Method:

Place the mercury end of the thermometer under the tongue for 3 to 5 minutes before removing it.
Avoid consuming cold or hot food or beverages immediately before taking the measurement. Wait for at least 20 minutes.
Keep your lips tightly closed and avoid biting the thermometer.
Normal oral temperature ranges from 36.3°C to 37.2°C.

Use of glass thermometer
forehead thermometer

Axillary Measurement Method:
Wipe the armpit area to dry it.
Place the mercury end of the thermometer in the armpit, ensuring a tight seal.
Leave the thermometer in place for 5 to 10 minutes before removing it.
Normal axillary temperature ranges from 36°C to 37°C.
Rectal Measurement Method:
Position the patient in a supine or lateral position, exposing the buttocks.
Use a thermometer lubricated with 20% soapy water.
Gently insert the thermometer into the rectum about 2 to 3 centimeters while holding the outer end.
After 3 minutes, remove the thermometer. Normal rectal temperature ranges from 36.5°C to 37.7°C.
By following these guidelines, you can ensure accurate and reliable temperature measurements using different thermometer types and measurement techniques.

Indications for Temperature Monitoring

Temperature Monitoring Criteria:
Patients with a body temperature of ≥39°C or ≤36°C should undergo temperature monitoring.

Elevated body temperature is commonly observed in cases of infection, advanced-stage cancer, Hodgkin’s disease, leukemia, hyperthyroidism, and other hypermetabolic conditions. Temperature monitoring is necessary for patients with such conditions. Low-grade fever can occur after accidents or surgical trauma, hematoma formation, presence of foreign bodies, fistulas, or urine or sputum retention.

Reduced body temperature can be seen in a minority of cases of septic shock, hypothyroidism, severe malnutrition, and hypothermia.


Temperature monitoring is a routine practice for hospitalized patients. Critically ill patients, due to infections, organ failure, and sedative use, are prone to temperature regulation disorders and abnormal body temperature. Monitoring methods such as rectal, tympanic, or esophageal temperature measurement are commonly employed for critically ill patients. The consequences of high or low body temperature vary depending on the duration. Therefore, it is recommended to monitor the core body temperature of critically ill patients at least once every 4 hours.

Parameters of Electronic Digital Thermometer

Patients undergoing active temperature interventions, such as inhaling heated air or using cold-hot temperature-regulating blankets, should have their body temperature monitored to guide treatment.

By closely monitoring body temperature and promptly identifying temperature abnormalities, healthcare professionals can better manage patients’ conditions and provide appropriate interventions.

Frequently Asked Questions

In this FAQ section, we addressed common questions related to thermometers. If you have other questions, you can communicate with us in time. We will answer for you.

Q:How does a digital thermometer work?

A: Digital thermometers use electronic sensors to measure temperature. The sensor detects changes in electrical resistance, which is then converted into a temperature reading displayed on the digital screen.

Q: Are digital thermometers suitable for infants and children?

A: Yes, digital thermometers are safe and reliable for use on infants and children. They provide fast and accurate temperature readings, making them ideal for monitoring children’s health.

Q: Are infrared thermometers safe to use?

A: Yes, infrared thermometers are safe to use. They are non-contact devices, meaning they can measure temperature without physical contact with the person or object being measured.

Q: Can I use a digital thermometer for measuring environmental temperatures?

A: Digital thermometers designed for body temperature measurement may not provide accurate readings for environmental temperatures. It’s best to use a thermometer specifically calibrated for environmental measurements.

Q: Do I need to clean the ear thermometer probe after each use?

A: It’s recommended to clean the ear thermometer probe with a soft, lint-free cloth or a cotton swab dipped in rubbing alcohol after each use. Be sure to follow the manufacturer’s instructions for cleaning.

Q:Are glass thermometers as accurate as digital or infrared thermometers?

A:Glass thermometers can provide accurate temperature readings when used correctly. However, digital or infrared thermometers are generally more convenient, faster, and often offer comparable accuracy.
