Pool thermometers: types and selection rules

Most commonly, water thermometers are used to measure the temperature of water in swimming pools, baths, or other storage facilities. They are sometimes even built into baby baths so that when bathing, the baby's delicate skin does not get burned or is not exposed to cold water.

In this paragraph, we will consider the characteristics that are endowed with pool thermometers designed to measure the internal temperature of the aquatic environment. So, a thermometer is a device for measuring the temperature of air, soil, water and similar substances. There are an incredible variety of types of thermometers, and they are only replenished, but more on that later.

The principle of operation of many thermometers is based on the property of a liquid to expand or, conversely, contract in relation to the operating temperature. Today thermometers are used in everyday life, agriculture, shops, hospitals, that is, almost everywhere where you can measure the temperature of something.

Consider the most popular types of thermometers used to measure water in swimming pools and in other cases.

• Electronic sensors are in great demand, since they have a simple principle of operation based on the electronegativity between the metal and the measured substance, for example, water. Often, a remote sensor is installed on such models for ease of use. The cost of the models starts at 200 rubles, which is quite democratic.

• Floating models are in high demand when you need to measure a large water surface, for example, a pool. It is simply set up, lowered to the surface and monitored for changes in temperature conditions.

• Liquid options often called "folk", as they are cheap, you do not need to configure them, the principle of operation is incredibly simple, and the service life exceeds the maximum possible. It is worth knowing that thermometers of this type are divided into mercury and non-mercury. In the first, mercury is used, in fact, a rather dangerous, but effective substance, and in the second, alcohol, pentane, acetone, and so on are usually poured.

When choosing a good thermometer, you should definitely pay attention to these parameters.

• Design reliability will be one of the fundamental parameters. Here you should pay attention to the strength of the material from which the case is made, to the level of its water resistance and build quality.

• Internal filling should be as safe as possible. For example, mercury thermometers are dangerous because if you break it, the mercury will disperse through the air, and it is a very dangerous substance. The best options would be electronic models, alcohol thermometers, infrared models.

• Specifications. These include the level of the maximum withstand pressure, which is under the water abyss, the maximum temperature drops, wear resistance, the quality of the device itself, and so on.

As we mentioned above, the range of applications for thermometers is incredibly wide. They can be used to measure temperature in households, hospitals, public places, and so on. In everyday life, you can measure the temperature of a child or an adult with a thermometer and find out how he feels. If you have a small child, then when bathing, the thermometer will become a faithful assistant to find a comfortable temperature regime for the water.

In public institutions like pool halls, many different types of thermometers are installed to regulate a comfortable temperature for visitors and, of course, professional swimmers. In such cases, the thermometers can be lowered to the bottom / middle of the water abyss, and the readings will be displayed on the LCD on land.
