Solar-Powered Pool Thermometer

The Perfect Part CA91_POOLTEMP is a digital floating thermometer that runs on solar energy with an LR44 backup battery. It measures water temperature from -20 to 50°C and withstands ambient conditions from 0 to 70°C. The white polypropylene body floats freely in pools, spas, ponds, bathtubs or aquariums.

Ideal for Basic Temperature Checks

This unit suits owners who want a simple, wireless reading without wiring or mains power. It is not for users who need data logging, wireless transmission to a phone or console, or an alarm function when temperatures leave a set range. Buyers requiring a fixed-mount probe or a multi-zone monitoring system should look at other devices.

Drop-In Installation

Place the thermometer in the water and let it float; no tools, plumbing or pairing are required. The solar cell charges in daylight and the LR44 cell takes over in darkness. The only common issue is debris or scale coating the sensor area, which can cause slow or inaccurate readings until cleaned.

The thermometer shows water temperature from -20°C to 50°C, covering typical pool and spa conditions.

Will the floating thermometer keep working if the solar panel gets covered by debris?

Yes, an LR44 backup battery powers the display when sunlight is insufficient, so readings continue uninterrupted.
