An inline thermometer is another important tool for your pool and spa because it helps you in tracking temperature near the heater of your pool or spa or even in the pool equipment room. Replace your old thermometer with the inline thermometers from Pentair. These thermometers show you the temperature of the water coming off your swimming pool solar system. You will be able to see the variation between the temperature of the water that is coming from the pool or spa and what is returning when your pool's solar system is active. It is also easy to install aside from having a large black dial that is very helpful since you can read the numbers easily.
