Aquarium Thermometer, Smart Digital Fish Tank Thermometer

Key features

• ✨ 𝐕𝐢𝐯𝐢𝐝 𝐋𝐄𝐃 𝐒𝐜𝐫𝐞𝐞𝐧 & 𝐑𝐞𝐚𝐥-𝐓𝐢𝐦𝐞 𝐖𝐚𝐫𝐧𝐢𝐧𝐠：This thermometer comes with a bright, high-contrast LED display that offers excellent visibility from wide angles, even under different light conditions. You can customize the HI/LO alert range (0–80°F) to your desired levels. Once the water temperature goes beyond the preset boundaries, a fast-blinking signal will notify you to take action—either warm up or cool down.
• 🔋 𝐄𝐱𝐭𝐞𝐧𝐝𝐞𝐝 𝐁𝐚𝐭𝐭𝐞𝐫𝐲 𝐋𝐢𝐟𝐞 & 𝐖𝐢𝐝𝐞 𝐂𝐨𝐦𝐩𝐚𝐭𝐢𝐛𝐢𝐥𝐢𝐭𝐲：Runs on the included 3V battery, which is already installed and designed for prolonged use—so you won't need to change it often. Works perfectly in freshwater, saltwater, tap water, and seawater. Its small footprint blends easily with your tank's décor.
• 🎛️ 𝐂𝐨𝐫𝐝𝐥𝐞𝐬𝐬 𝐓𝐨𝐮𝐜𝐡 𝐂𝐨𝐧𝐭𝐫𝐨𝐥：With no cables to clutter the tank, this device keeps your setup neat. The touch-sensitive button allows a long press (1s) for power on/off, and a short press (0.5s) to switch to setting mode. While in setting mode, another short press lets you adjust the HI/LO values. After 10 seconds without operation, it automatically enters sleep mode to save energy.
• 🎯 𝐇𝐢𝐠𝐡-𝐀𝐜𝐜𝐮𝐫𝐚𝐜𝐲 𝐌𝐞𝐚𝐬𝐮𝐫𝐞𝐦𝐞𝐧𝐭：Each unit is double-calibrated in a lab setting, ensuring an error margin of just ±0.9°F. The reading refreshes every 30 seconds, giving you prompt insight into any fluctuations that could affect delicate aquatic life and plants.
• 🛠️ 𝐂𝐨𝐦𝐩𝐥𝐞𝐭𝐞 𝐏𝐚𝐜𝐤𝐚𝐠𝐞 & 𝐑𝐞𝐥𝐢𝐚𝐛𝐥𝐞 𝐒𝐮𝐩𝐩𝐨𝐫𝐭：Comes with 1 thermometer, 1 pre-installed battery, and 2 reusable adhesive pads. If you have any questions about setup, performance, or suitability, simply check the user manual or reach out to our support team for help.
