A thermometer is an instrument that is used to measure the temperature of the surroundings of the body. The outdoor thermometers reflected here are basically used to detect temperature changes in the environment.

Outdoor thermometers are currently helping in various industries and technology as monitoring devices in scientific research, meteorology, and medicine. To record accurate information from the thermometer, it must be placed in a strategic location where there is free air circulation.


Factors to Consider While Setting Up an Outdoor Thermometer

Do you have a thermometer?

Before deciding where to place the thermometer, it is necessary that you have one. A digital thermometer or a mercury thermometer works best. The thermometer needs to be in good condition so as to give accurate readings after setup. A thermometer can be purchased online or at a local store at a fair cost.


This refers to the space between your house and the strategic position of the outdoor thermometer. The thermometer should be placed further from the building to avoid inaccurate information due to air blockage that occurs. It also recommendable to place it where there is a shade to avoid precipitation caused by direct sunlight.

In case you want the thermometer to be around your house, it must be higher than the roof of your house. Therefore, if your house is 8 feet high the thermometer should be a few feet higher. You should not place it near the windows since there could be some blockages and the flow of air may not be enough to give the best and accurate results.

How far is the pavement?

Ensure that the thermometer is 40 meters away from the pavement. The reason for this is that pavement contains concrete that has a tendency of absorbing and releasing heat.

The contractions in the pavement will automatically interfere with the readings. The reason for this is because the ground has different temperature ranges due to moisture and heat from the sun. The conditions on the ground can interfere with the thermometer readings.

Thermometer height

The height should keep off the thermometer from getting in contact with the ground temperature. In case there is some interference, it may interfere with the readings.

Therefore, the thermometer must be placed above 5 feet from the ground to ensure that the temperature on the ground does not come in contact with the sensor. A thermometer placed below the height of a building will always give inaccurate readings that cannot be depended upon.

How is the airflow?

A flat area is the best place to put the thermometer since the air is always flowing freely. Sheltered areas such as inside the house or areas near windows are not recommended as the circulation of air is hampered. Hilly areas should be exempted because it can be hard to get flat spaces to position a thermometer.

Therefore, you can place your thermometer at an inclined angle. However, readings of a thermometer in such an inclined area may not be accurate as those taken on flat surfaces.

Is it the rainy season?

The rain can destroy a thermometer if it is not properly sheltered.  Maintaining this device is tricky and can become expensive if extra caution is not taken. Mercury enables the thermometer to work and gives readings that can be destroyed if rainwater gets in contact with it.

The best action to take is to make a shelter around the thermometer to prevent rain from destroying the device. The shelter should be simple and small in size to avoid inaccurate readings. However, the shelter should be placed only in the rainy season since it can act as a shade when it is sunny.

Away from direct sunlight

The sensor will give higher readings if the thermometer is exposed directly to the sunlight. To get the best readings, ensure there is a shade and there is enough air space at a proper height to avoid blockage. Direct sunlight will make the thermometer give wrong information that may be unhelpful to the user.

How Often Should You Calibrate an Outdoor Thermometer?

  • Monthly

To avoid inaccurate readings, it is advisable to calibrate your outdoor thermometer on a monthly basis. This is done especially if you have been making frequent measurements within the month. The critical measurements can interfere with readings in the future if the thermometer is not calibrated regularly.

Calibrate an Outdoor Thermometer

  • Before a major project

To avoid project risk, it is advisable to follow the instructions given before starting using the readings before a major project.

  • Project requirements

Some projects make it a must to calibrate the device and have them certified. However, failure to follow the instructions can ruin the integrity of the project.

  • Annually

It is calibrated annually if the measurements taken within the year are not critical. It is stated to be the right balance between prudence and cost and for the accuracy of the device, it must never go beyond.

  • After a major project

This helps to return the device back to its normal state after testing is completed in a project. It helps to determine the accuracy of the results and find out the margin error of the project.

  • Never

There is no need to calibrate the device if it is only used for gross checks and if you calibrate in such a state the readings will not be accurate. In this case, there must be another thermometer that is regularly used and the spare one that does gross checks.

  • According to the manufacturers’ recommendations

The manual will always direct the user whether to calibrate or not. Manufacturers must have a good reason to state in the manual that the thermometer needs to be calibrated. Instructions provided in the manual have to be followed to the latter to avoid inaccurate measurements

  • After a knock over

This happens after overload of internal protection whereby it is advisable to recalibrate the device and confirm that it is safe. Lack of proper check up of the device will lead to inaccurate readings.

How to Adjust an Outdoor Thermometer

Iced water has to stay for 9-16 minutes to allow the temperature to stabilize. The thermometer has to achieve the lowest degree and to achieve this it has to be put in an ice bath. Before adjusting the thermometer to the freezing point of water, the current temperature of the outdoor thermometer must first be recorded.

Steps followed while adjusting a thermometer

  • Fill a glass with ice cubes and top off with cold water.
  • Mix the water and ice cubes and wait for at least 3 minutes.
  • Mix again and place the thermometer in the glass without letting it touch the glass.
  • Ensure that your hands do not interfere with the glass since it will affect the readings.
  • The temperature should read 0 degrees Centigrade or 32 degrees Fahrenheit.

How do you know if the Outdoor Thermometer is Accurate

The accuracy of an outdoor thermometer is noted if it registers 0 degrees or 32 degrees Celsius in iced water. To achieve accuracy, the stem of a thermometer has to be inserted 0.9-inch-deep in the ice water whereby the stem should not be allowed to touch the glass.
