Firelex Wireless Solar Pool Thermometer Indoor & Outdoor Monitoring

•       Pool season is starting up right now — get this listed and shipped before your first swim of the year, so you never have to guess your pool temperature again or trudge out in bare feet just to check if the water's warm enough.

•       Most wireless pool thermometers run on AA or AAA batteries that need replacing mid-season — this one charges itself with solar and runs 1–3 months on a single charge, so you can set it and forget it from Memorial Day to Labor Day without touching it once.

•       This exact Firelex IBS-P03R solar pool thermometer with indoor display is listed at $70–$100 on Amazon — you're getting the same brand-new, sealed unit here for less, shipped fast by a dedicated reseller who stands behind every sale.

Stop walking to the pool. Stop replacing batteries. The Firelex Solar Pool Thermometer wirelessly sends your pool, hot tub, or spa temperature straight to the indoor display on your counter — no app, no Wi-Fi required, just a clear readout up to 980 feet away. Solar-charged and battery-backed, it keeps working long after you've forgotten it's out there.

Key Features

•       Solar-Powered — No Battery Replacement → The IP68-sealed solar panel charges fully in 10 hours of sun and runs continuously for 1–3 months even in shade. No more opening your skimmer basket or pulling the thermometer out of the water to swap batteries mid-season. Set it, float it, forget it.

•       980ft Wireless Range — Check from Inside → The floating sensor transmits pool temperature to the indoor display up to 980 feet (300 meters) away — through walls, fences, and across large properties. Check your spa temperature from the couch before you get up. See the pool temp from the kitchen before the kids get their suits on.

•       IP68 Waterproof — Truly Submersible → IP68 is the highest standard waterproof rating — it survives submersion up to 10 feet, saltwater, chlorinated pools, hot tub chemicals, and the roughest poolside chaos. Unlike cheaper IP65 or IPX7 options, this sensor is sealed as a single unibody unit with no seams that can fail over time.

•       ±1.8°F High-Precision Sensor — Updates Every 10 Seconds → The lab-calibrated sensor measures from -40°F to 158°F, covering everything from frozen pipes to hot tub use. Readings update every 10 seconds — meaningful real-time monitoring, not a slow 1-minute delay. Tracks 24-hour and all-time max/min temperatures on the indoor display.

•       Indoor Display — Pool Temp + Home Temp + Humidity → The indoor receiver isn't just a relay — it's a full environment monitor. See your pool water temperature, your home's indoor temperature, and humidity level all on the same screen. The Comfort Indicator shows when your pool is in the ideal comfort zone (customizable 78°F–86°F). Also tracks daily max/min records.

•       Supports 3 Sensors on One Display → The indoor receiver can pair with up to 3 Firelex/INKBIRD IBS-P03R pool sensors simultaneously — ideal for homes with a pool and hot tub, koi pond and spa, or any multi-water-body setup. Includes 1 sensor; additional sensors sold separately.

•       Multi-Use: Pool, Hot Tub, Spa, Pond, Ice Bath → Works in any water environment that benefits from temperature monitoring. The wide -40°F to 158°F range covers ice bath cold plunges, boiling hot tub temps, koi pond seasonal monitoring, and everything in between. Especially useful for maintaining optimal chlorine efficiency (ideal pool temp: 78–82°F).

•       2M Hanging Rope Included → The included 2-meter (6.5-foot) rope lets you anchor the floating sensor to a pool ladder, railing, or lane marker so it stays in a consistent position and doesn't drift. Also works as a tether to retrieve the sensor easily from large pools.
