How to Differentiate between Various Pool Thermometers?
There are several ways in which you could distinguish the different types of thermometers on the market. One way would be by considering their design. On that account, you will find floating and hanging pool thermometers out there.
Usually, floating and hanging thermometers might be analog or digital. Meanwhile, when it comes to handheld thermometers, they are typically digital.
Floating pool thermometers
As the name clearly states, a floating pool thermometer is meant to float on the surface of the water. Basically, it will assess the temperature due to the presence of certain sensors inside the unit.
In terms of accuracy, they might not be as efficient. That has to do with the fact that they might not submerge entirely in the water. Therefore, they might not pick up the precise temperature in the pool, but of the water and the air surrounding it.
As for the convenience of such models, they require your minimum input, so to speak. All you have to do is throw them in the water and that’s about it.
Hanging pool thermometers
For the most part, a hanging pool thermometer should be attached to the side of the pool. Another option would be placing it on the ladder. This way, you can be sure that the thermometer is entirely submerged in the water. This is important in order to get an accurate reading.
When it comes to hanging pool thermometers, you can usually choose between analog and digital models. The readings are quite accurate. That’s because the sensor is immersed in the water completely.
Handheld pool thermometers
As you might expect, handheld pool thermometers are digital. What you do is keep the thermometer in your hand just as you would hold a gun. And there is an infrared laser that you can direct at the water so that you can see the right temperature.
In terms of accuracy, handheld pool thermometers are fairly accurate.
