VAYINATO Aquarium 4-Pack Sticker Thermometers for Convenient Temperature Monitoring Aquarium Tool

QUANTITY: You get 4 sticker thermometers in a pack, which allows you to monitor the temperature in different areas of your aquarium or use one as a backup. ADHESIVE DESIGN: These thermometers usually have adhesive backing that allows you to stick them to the external glass surface of your aquarium. This makes them easy to install and move if needed. TEMPARATURE DISPLAY: Sticker thermometers typically display the temperature on a scale or color-coded range, making it easy to read the temperature at a glance. NON-INTRUSIVE: They do not require submersion in the water, so they won't disturb your aquatic environment or take up space inside the tank. ACCURANCY : While sticker thermometers are generally accurate for general temperature monitoring, it's a good practice to verify their readings periodically with a submersible thermometer to ensure accuracy.
