Build Quality 

The next factor which needs a close look is the build quality of the thermometer. Getting the best quality thermometer is the best one for you. Getting cheap ones is never the answer as they are not that durable and won’t be able to give an accurate reading of the temperature as well.

Floating Thermometers are the ones that are stuck using a suction cup or simply kept inside the water column. These thermometers are quite hard to read from outside the tank. As most of these are made of glass, so it has a chance of breaking. 

The Stick on thermometers come as the type which is attached to the outer side of the tank. Although this thermometer has a higher chance of being inaccurate as it is attached to the outer side, therefore the outside temperature influences the reading of temperature. 

The digital thermometers come with a cable and a display. You can attach it to the tank at all times or at certain times to check the temperature. Some of the digital thermometers run on a battery or have a plug. Some even have the function where you can set up the needed range of temperature and will set off if that range is crossed.
