Different models of digital outdoor thermometer offer a wide variety of functions. Some of the essential features to look for in your outdoor thermometer include:
Temperature Accuracy
Temperature accuracy may not be at the top of your list of features if you just want to know what to wear, however, for people who rely on temperature measurements for controlling the ambient temperature in greenhouses or food storage areas, precision is an important issue. Look for digital thermometers with an accuracy range of at least ±0.4F.
Large Display
If you are looking for an easy to read digital thermometer that can be seen from the warmth and safety of your home, you need a unit with a large, clear display.
Avoid displays with too much information cluttering the screen. Opt for an outdoor thermometer will a scrolling function that has the temperature as the primary display mode but also allows you to access information on humidity, barometric pressure, and other weather conditions as necessary.
Backlight
A backlight display also allows you to see vital information on your outdoor thermometer, especially in low light conditions. Blue or white LED backlights create a high contrast between the digital reading and the rest of the screen for better visibility.
Easy Programming
Avoid the need for constant calibration with an easy-to-program unit that allows you to set a high/low-temperature alarm and gather information on a variety of weather conditions.
Long Battery Life
Wireless capability allows for greater flexibility when gathering weather data. However, to ensure consistently accurate readings, make sure your outdoor thermometer and sensor have long battery life. Look for units with a minimum battery life of at least 12 months.
Wide Transmission Range
The sensors collect weather data and transmit it back to a central unit in your home. The most accurate and informative models have a wide transmission range allowing you to use the thermometer for a more versatile variety of applications. The best digital outdoor thermometers have a transmission range between 200-500 feet from the central unit location.
Multifunctional
For most people using a digital outdoor thermometer, the temperature isn’t the only measurement they are seeking. Look for a multifunctional thermometer that accurately measures humidity and barometric pressure to make weather forecasts, moon phases for tidal predictions, and wind speed.
Outdoor thermometers can be fun and informative. They can be utilitarian in appearance, or they can be elaborately beautiful. Thermometers can be a stand-alone item or part of your home weather station. Some of them can even send information to your computer or phone. Liquid-in-glass and digital thermometers give the most accurate readings.
