HEIMVERT Wireless Digital Pool Thermometer – Floating, Easy-to-Read Display, IPX8 Waterproof – Indoor/Outdoor Sensor for Hot Tubs, Swimming Pools, Ponds & Aquariums (Azure, 2 Pack)

High Precision Sensing: The floating temperature sensor features a high-precision chip that detects temperature changes with an accuracy of ±1°C (±2°F). It measures temperatures ranging from 0°C (32°F) to 50°C (122°F), making it suitable for a wide variety of environments.Long-Range Transmission: Equipped with upgraded wireless technology, the thermometer’s base station can connect with a sensor up to 300 feet away (under ideal, interference-free conditions). The sensor takes water temperature readings every 5 seconds, and the base station refreshes the display every 50 seconds for real-time monitoring.3-Channel Monitoring: With 3-channel link technology, one base station can connect to up to three sensors simultaneously. This allows you to monitor the temperature of three different water sources at once—enhancing both the versatility and fun of using your pool thermometer.IPX8 Waterproof: Designed for aquatic environments, the sensor is built with multiple sealing rubber rings to achieve an IPX8 waterproof rating, effectively minimizing water damage. Note: Please make sure to tighten the lid before use to prevent issues caused by improper sealing.Easy to Use: The wireless pool thermometer operates on AAA batteries (not included). Once powered on, the base station and sensor automatically enter pairing mode—no complex setup required. The display clearly shows temperatures from both indoor and outdoor sensors, and the simple interface makes operation easy for everyone.
