As for accuracy, so far it tracks the temperature reading well enough to match up with the local area airport weather station exactly as shown on my ecobee HVAC thermostat without any calibration to this old Aqualink system at all. I just unscrewed the 2 wire terminals for removing the dead sensor and replaced it with this one and made sure that my placement of the sensor was not in direct sunlight or near other potential heat sources while being in a space where it could also get good air flow and I’m very happy with about 2 months of using this inexpensive sensor on my Aqualink system so far as it gives an accurate reading and has triggered the freeze protection twice on the two cold southern winter nights last month. ### ⭐⭐⭐ OK for the price, new ones don't seem to last as long at much older OEM parts. *by A***C on Reviewed in the United States on March 23, 2021* Bought this part in Spring 2018, for about $25 at the time, to replace water temp sensor used with RS6 AquaLink. The original sensor installed in 2003 lasted 15 years. This one has now failed after just under3 years. Considering that the Zodiac (Jandy) original part is $60 on AMzN, then the current price of $20 may be worth it, even for the short life span. I bought a second one of these in late 2020 to replace the air-temp sensor for the RS6 (original--that lasted 17 years), and it is still working fine after 4 months or so. FYI: Symptom of a failing sensor both times were that temp reading is higher than normal, and over time, it just keeps going up over several weeks' time. It will read a little high at first, then keep going up until it is obviously ridiculous. There are several aftermarket suppliers/brands of these same sensors, likely al made in the same Ch*nese factory, so you might as well pay the lowest price. ### ⭐⭐⭐⭐⭐ Works well; highly recommended *by M***E on Reviewed in the United States on April 24, 2021* Pool thermistors have a way of decaying over time in fast flowing, warm, chlorinated water. I replaced mine 4 years ago, and it worked great until one day the pool temp was listed at 175 degrees, and the real temp was 72.I purchased this replacement, removed the old one (turned out the plastic insulation surrounding the thermistor had cracked and eroded away), and then installed the replacement rather easily (it leaked at first, so I reinstalled it and the leak disappeared). The thermistor temp reading now exactly matches the pool temp obtained with a thermometer physically in the pool.Hopefully this replacement will last for a few years. I'd call it a good deal; cost me ~$20 and 15 minutes of my time, where if I had a pool repair guy do the job it would have run about $150. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hu/products/41773466-replacement-for-jandy-zodiac-7790-temperature-sensor-probe-12-month](https://www.desertcart.hu/products/41773466-replacement-for-jandy-zodiac-7790-temperature-sensor-probe-12-month) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-08-06*
