Which type of thermometers are required to be used in swimming pools?

Shatterproof thermometers are required for use in swimming pools primarily because safety is a top priority in aquatic environments. These thermometers minimize the risk of injury associated with broken glass, which can occur if a glass thermometer is dropped or otherwise damaged. In a pool setting, where people are often distracted and moving about, the potential for accidents increases, making shatterproof options more suitable.

Moreover, shatterproof thermometers are designed to withstand the conditions often found in and around swimming pools, including exposure to water and possibly harsh chemicals used for pool maintenance. This durability ensures that they provide accurate temperature readings without the risk of dangerous breakage, which could not only injure users but also contaminate the pool area.

While other types of thermometers—like digital and glass—can provide temperature readings, the safety and reliability offered by shatterproof thermometers make them the preferred choice in swimming pool settings.
