It is recommended to replace a thermometer every 1-2 years to ensure accuracy and reliability. If a thermometer is damaged, it should be replaced immediately.
A Thermometer's accuracy can be improved if it is placed in an area where there is not an object that touches it that can influence a temperature shift.
Before using a thermometer, it is important to clean it with soap and water, rinse thoroughly, and dry it properly. This is to ensure that the thermometer is free from any contamination that could affect the accuracy of the temperature readings.
A laboratory thermometer is used to check the temperature, or changes in temperature, of an object with precise accuracy.
A thermometer can be calibrated by placing it in a temperature-controlled environment, such as an ice bath or boiling water, and adjusting the reading to match the known temperature. This process ensures the accuracy of the thermometer readings and allows for corrections to be made if there are any discrepancies. Calibration should be done regularly to maintain the reliability of the thermometer.
There are several ways:use a liquid whose coefficient of thermal expansion is near constant,use a liquid with low vapour pressure,use a bulb with a relatively larger bulb and thinner stem,calibrate the thermometer carefully.
You can check the accuracy of a thermometer by immersing the sensor in a mixture of ice and water, which should read 0°C (32°F), or boiling water, which should read 100°C (212°F) at sea level. If the readings are off significantly, the thermometer may need calibration or replacement.
To ensure the accuracy of your oven's temperature, you can calibrate it by using an oven thermometer. Place the thermometer in the center of the oven and set the temperature to a specific degree. After preheating, compare the thermometer reading to the set temperature to adjust as needed.
When calibrating a thermometer using the ice point method, you should set the thermometer to 0 degrees Celsius (32 degrees Fahrenheit) after placing it in ice water. Ensure that the thermometer is fully submerged in the ice-water mixture and that it is not touching the sides of the container for an accurate reading. Adjust the thermometer to read exactly 0 degrees Celsius, if necessary. This calibration point helps verify the thermometer's accuracy at the freezing point of water.

No, it is not recommended to leave the thermometer in the meat while cooking as it can affect the accuracy of the temperature reading.
Before choosing a thermometer for a specific job, you should know the temperature range required, the accuracy needed, the response time, the environmental conditions (e.g. humidity, pressure), and any calibration or certification requirements. Understanding these factors will help you select the most suitable thermometer for the job.
