Best For window: ambient wear hot tub Temp Sensor

Buy on Amazon

The ambient wear hot tub temp sensor's superior materials makes sure that it ages well with use. When it is too hot or too cold this is the best way to know the pool temp from inside the house. This is one of the first floating type of pool sensors that has worked as described. The float unit has a 6-8 inch long piece that contains the temp gathering unit, so it will record whatever the temp of the unit is regardless if submerged in water or not. It is so nice to be able to sit on the deck, or on the porch and be able to just read the wireless screen without having to go all the way down to the pool to find the thermometer.

This unit has TWO gasket surfaces to seal the floating temp transmitter. The min/max temperatures are good enough and the reading does come back. The unit is weather and waterproof since it does float in the pool.

Best For monitoring spa Temp: Amtast hot tub Temp Sensor

Buy on Amazon

Not everyone likes to purchase sensor for their daily usage, but the amtast hot tub temp sensor would be an anomoly. This swimming pool thermometer is a wonderful asset for keeping track of how comfortable your pool will be when you get in. It works well with a small stainless wire to hold it to a connection point on the pool wall. There is a small tab with a 1/8" hole just below the blue ring. The remote sensor, which bobs around in the pool, will find its way to the skimmer eventually and disappear from sight. It’s also hard to read the thermometer unless you are directly over it as the display will show ALL in sunlight.

This product is so easy to monitor the temperature of the pool without having to go and pull the thermometer out of the pool and look at the temp. The pool unit is generally good for more than a year.
