Penn-Plax shorefins™ Digital Thermometer

The digital aquarium thermometer is designed for quick and reliable water temperature monitoring, featuring an easy-to-read display for at-a-glance viewing. Its external mounting design attaches to the outside of the aquarium, while a probe and wire measure water temperature accurately inside the tank, keeping the display unit dry and protected. It can display temperatures in either °C or °F and includes a memory function that records previous readings as well as a MAX/MIN mode to track high and low temperature ranges. This helps ensure stable aquatic conditions for fish and other aquarium inhabitants. Powered by an LR44 battery with an approximate 3-year lifespan, it provides a convenient and long-lasting solution for maintaining proper aquarium temperature control.
