Pool Thermometer Buyer’s Guide

Purchasing the right thermometer becomes less complicated if you take into account some important factors. First of all, you need to consider a few key features that any pool thermometer comes with. Plus, keeping in mind your needs and preferences is important. So, let’s look at some essential points that you need to remember to make the right choice.

  1. Display

This, of course, is a must to consider when you are buying pool thermometers. The display must be clear enough so that you can read the temperature easily. Average products often come with small markings that are very difficult to read. 

So, you must check the details regarding the display of the product. Note that some products come with backlit displays that help you read the temperature at night as well. In case you don’t have a clear vision, it is better to buy thermometers with larger markings or screens. 

  1. Type

Thermometers are either digital or analog, so you must decide which one will be better for you. Digital products come with sensing probes that transmit the reading to the display. 

As for analog thermometers, they have a thin display made of glass or plastic with mercury or alcohol to show the temperature. Note that digital products are slightly more expensive than analog ones, since the accuracy is usually better in the case of the former type. 

  1. Accuracy

Well, the accuracy decides how better you can maintain the pool temperature with the product. Inaccurate readings would make the adjustment imperfect, which will give you warmer or cooler water than you want. 

So, make sure you check the information on the accuracy or some customer reviews while going through the details of a product. Note that the products that we’ve included in our list rank high in terms of accuracy. 

The covered area of the pool water retains heat longer. Also in a canopy you can bring heating. The polycarbonate lid keeps the temperature of the water, but also protects the pond from debris

Verdict

Now that we have reached the end of our guide, we hope you’ll easily be able to choose the best pool thermometer. 

But before we bring down the curtains, let’s take you through our favorites on the list. In our opinion, the eLander A15-EL Pool Thermometer is a high-performing as well as a cost-effective option to go for.

However, if you don’t mind going for a more reliable and efficient product that’s a tad more expensive, the Pentair R141036 Pool Thermometer will be a great choice. 

On the other hand if you are searching for a more attractive product, then the Game 7000 Pool Thermometer will be a perfect option. It comes with a cute derby duck-shaped top that will seem quite appealing to any kid. 

With that, we’ll sign off. Till we meet again, take care.
