What is an outdoor thermometer?
The rural meter is a scientific tool that reads the air temperature outside. There are three main types of outdoor thermometers: bulb thermometer, bimetallic belt thermometer and digital thermometer. Each species works in a somewhat different way, but they all work to allow people to read outdoors.
The outdoor bulb thermometer is the most basic type. It is usually made of glass and is filled with mercury. As the temperature rises, mercury turns into volume. As a result, mercury moves along a glass tube. In the alternative, if the temperature drops, the mercury takes less space in the glass tube and drops down.
Although an outdoor thermometer filled with mercury is an accurate way to say temperature, it can be problematic. Mercury is a toxic substance. If the thermometer breaks and the mercury flows from the glass tube, it must be properly cleaned to prevent serious health problems.
The outdoor thermometer of the bimetallic strip looks like a dial. It is made of spring coil. The coil consists of two kindHoly metal pieces that are attached to measure the temperature outdoors. It works when both metal pieces are expanding or withdrawing at different rates. For example, if one piece of metal keeps warm, the coil will be forced to expand and the hand of the dial is crawling up. If the temperature drops, the metal cools faster, infects the coil and moves the hand of the dial down.
Digital or electronic outdoor thermometer is the most modern and is also considered to be the most accurate. Inside the thermometer there is a thermoresistor that changes its resistance according to the temperature. Furthermore, the sensor on the microcomputer reads the temperature and digitally displays it.
There are countless style options for all outdoor thermometers. They can be hung from the house, move it to the window or put it in the garden. While digital outdoor thermometers may require a new set of batteries or a separate energy source from time to time, there will be no bulb or dialing thermometer. In additionAt night it lights up, making it easier to read the temperature when it is dark outside. Some models have only one sensor, but more expensive models have multiple sensors that can be placed in different areas on the plot and give the most accurate value.
Regardless of the type of outdoor thermometer, the location is one of the most important factors for accurate reading. It should be in a shady area with lots of air stream. In addition, at least five feet (1.52 m) should be placed above natural grounds such as grass or dirt - not above the asphalt. In fact, it should not be located closer than 100 feet (30.5 m) on the street or on concrete. Planing this near sprinkler systems or high buildings can also cause inaccurate reading.
