Reptile Ventilation Fan with Hygrometer & Temperature Display, Auto Adjusting Humidity & Temperature, for Aquariums & Insect Tanks, 2-Pack

[Smart Auto Adjustment]: The fan will turn on when the actual temperature or humidity exceeds the preset values and stop when it drops below them. Even after a power outage, the device will remember the previous settings.

[Clear & Easy-to-Read Display]: The bright blue display clearly shows the current temperature and humidity, so you can monitor changes anytime. Place the unit on the grid above the aquarium for clear visibility from any angle.

[Enhanced Ventilation System]: The main fan and auxiliary fan work together to enhance ventilation, allowing your plants to breathe freely, improving air quality, and creating a safe environment for your reptiles.

[High-Precision Sensor]: It comes with a sensor that accurately monitors your aquarium's temperature and humidity (accuracy: ±2% RH, ±2°F). The sensor has suction cups to stick to the glass, but it's not waterproof.

[Multi-Function Design]: This reptile ventilation fan is both an efficient ventilation system and a temperature and humidity monitor, keeping your aquarium or insect tank environment perfect for your reptiles.
