Replacement Pentair 520272 Air/Water/Solar Temperature Sensor, 20-Feet Cable for Pool/Spa (2 Pack)

I usually purchase Pentair Temperature Sensors but the cost had increased 100% since I last bought one. This product not only is half the cost it also comes with TWO sensors. We decided to give it a try and so far so good. Works Great.

Works great.

I got the dreaded 170 degree reading for my pool and I knew that was it, the sensor had gone bad.Overall these are a good value, but their accuracy is for hell. My sensor ended up to be 3 degrees off or so. Depending on what kind of system you have, you might have the ability to adjust the system to compensate for it's lack of accuracy like mine does. If not, you may just have to make due. Because I could adjust, I only subtracted one star. If these things end up not lasting, then I'll pull another star or two, but they've been around for almost a year and no problems so far.

I have about 40 feet between my solar controller and the water sensor. You can get the 25-foot one for under $20, but the 50-foot one is $150! It is just a crazy price differential that I wasn't going to pay. I figured I could splice two together I'd be way ahead even if I had to do it five more times.These look like the same quality as the name-brand options and I got two for under $20. I spliced the two together using solder and shrinkwrap. Then I coated it with liquid tape and let it cure for a day since the conduit can get some moisture in it. I installed it and it read the water temp accurately. Well worth the extra work.

Easy exact replacement. Works perfectly. Great value and I have a spare.

The advertisement stated there were 2 in package, my order only came with one. Luckily at this time I only need one but I was counting on having a spare. Tried to put this info in other place of website with no luck only wants to be returned. I will keep and install.

Good quality and fixed my temp issue for water temperature. No longer 127 degrees in april in florida. Within seconds after turning on water was 77 degrees and solar would now turn on.

The local pool business quoted me almost $90 for just one of these sensors. I got both of these for $21.
