Manufacturers recommend calibration intervals. Follow their recommendation.
In practical terms, recalibration may be required sooner if the instrument is heavily used, used in many and diverse locations regularly or if it sustains damage. Knowledgeable users know when unusual results occur and get their instrument repaired and/or calibrated.
There is another process that helps ensure accurate results and reduces cost and loss of use - compare your meter's performance with that of a recently calibrated unit in a side-by-side test. This does not re-certify a meter but it does reduce the likelihood of using an out-of-spec meter and having to re-survey a site.

What is the mercury?
Mercury is most often found in thermometers.
How often should a thermometer be calibrated?
Every 4 Years Every 4 Years
Different types of thermometers and their uses with pictures?
There are several types of thermometers. Clinical thermometers are used to measure the body temperature of the patient. Ear Thermometers make it an accurate point to measure the body temperature. Pacifier thermometers are used to check the body temperature of babies or infants. Underarm thermometers are kept in the underarms to measure the body temperature. Not to mention the food thermometers that are often used for checking the heat of the oil or pop up to let you know when the meat is done.
How is the Celsius scale calibrated?
The Celsius scale is calibrated based on the freezing and boiling points of water. It is set so that 0 degrees Celsius represents the freezing point of water and 100 degrees Celsius represents the boiling point of water at standard atmospheric pressure.
What are alternatives to thermometers?
Some alternatives to thermometers include thermal cameras, infrared thermometers, and non-contact forehead thermometers. These devices can measure temperature without physically touching the person.
What are thermometers measured in?
Thermometers may be calibrated in degrees Fahrenheit or degrees Celsius.
For thermometers to read temperature correctly they must be?
Calibrated
Do thermometers measure in Celsius?
Thermometers can be calibrated to measure temperature in Celsius, Fahrenheit, or Kelvin. Most common thermometers used for everyday purposes usually measure temperature in Celsius.
When were the first calibrated thermometers made and where?
The first calibrated thermometers were made in the early 1700s by Italian inventor Santorio Santorio, who used a sealed glass tube with a numerical scale to measure temperature. This marked the beginning of the modern temperature measurement era.
When was the first accuratley calibrated thermometers made and where?
The first accurately calibrated thermometers were made in the early 18th century by Gabriel Fahrenheit in the Netherlands. Fahrenheit's mercury-in-glass thermometer established a standardized temperature scale, enabling precise measurement of temperature variations.
How are homemade thermometers different from commercial versions?
The homemade ones have not been calibrated while the commerical ones have been.
What is the temperature used on laboratory thermometers?
Typically, laboratory thermometers are calibrated to measure temperatures ranging from -10°C to 110°C. However, specialized thermometers can be used for extreme temperatures outside of this range.
Why the thermometer is accurate?
Thermometers are accurate because they are calibrated to measure temperature with a high degree of precision. They are calibrated based on fixed points like the freezing and boiling points of water, ensuring consistent and reliable readings. Additionally, modern thermometers use advanced technology to improve accuracy, such as digital displays and sensors.
Why are thermometers calibrated?
Thermometers are calibrated to ensure accuracy in measuring temperature. Calibration involves comparing the readings of a thermometer to a known standard to verify its correctness and make any necessary adjustments. This helps maintain the reliability and precision of temperature measurements for various applications.
Are thermometer accurate?
Thermometers can provide accurate temperature readings if used correctly and calibrated properly. Digital thermometers are typically more accurate than analog ones. It's important to follow the manufacturer's instructions for usage and maintenance to ensure accuracy.
How accurate is a thermometer?
A thermometer can be accurate if used correctly and calibrated regularly. However, factors such as environmental conditions and handling can affect its accuracy. Digital thermometers tend to be more accurate than traditional mercury thermometers.
What is the mercury?
Mercury is most often found in thermometers.
