Floating Thermometer for Pool, Hot Tub and Aquarium

Floating Pool and Spa Thermometer with Large Easy-Read Scale

Keep water at the perfect temperature all season long. This floating thermometer drifts upright in pools, hot tubs, ponds or aquariums and shows crystal-clear readings in both °C and °F, so you know exactly when to jump in or switch on the heater. Built from shatter-resistant plastic, it shrugs off sunlight, splashes and the occasional cannonball while a tether eyelet stops it drifting into the skimmer.

Key Features and Specifications
- Measures water temperature from 0 to 50 degC (also marked to 120 degF for reference)
- Large 16 mm high digits on a 4.5 cm wide scale for instant poolside reading
- Float ring keeps the 19.5 cm long body upright in moving water
- Shatter-resistant ABS plastic housing stands up to drops and strong sunlight
- Built-in hanging loop and tether hole to stop the unit drifting into skimmers
- Size 4.5 x 4.5 x 19.5 cm, weight 0.06 kg

Ideal Examples of Usage
- Check spa water before kids climb in to make sure it is under 38 degC
- Monitor garden fish pond temperature to protect koi during heatwaves
- Balance chemicals in an above-ground pool by tracking daily temperature swings
- Hang from a hot-tub jet with a short cord so the scale stays easy to reach
- Float in an indoor hydrotherapy bath for reliable rehab session readings

Why This Thermometer Is the Perfect Buy
- Oversize scale saves squinting; read from pool edge instead of lifting the unit out
- Dual metric and imperial marks help guests who still think in degF
- Fully floating design means no sharp probe ends to scratch pool liners
- UV-stable plastic keeps the white finish bright season after season
- One low-cost tool covers pools, spas, tubs, ponds and aquariums alike

Interesting Facts About Pool Thermometers
- Most pool heaters are set around 27 degC; every extra 1 degC can raise energy use by roughly 10 percent
- Fish such as koi grow fastest between 20 and 25 degC, making a float gauge crucial for healthy feeding schedules
- A 50 degC upper limit is high enough to check solar pool blankets that can spike small surface pools in midsummer
- Early pool thermometers used mercury; modern plastic units avoid toxic metals and are safer for families
- Floating designs sample the top 15 cm of water where swimmers actually feel the temperature first
