- Easy to read and operate: monitor temperature at the touch of a button, view readings on a crystal-clear large display, and switch temperature units by pressing and holding the button for 3 seconds. - Battery powered design: built-in button cell provides energy-efficient, accurate readings. Replace the LR44 battery after use to maintain precise monitoring. - Convenient installation options: choose the wired model with suction cups or the wireless version with an adhesive mounting to place the gauge and sensor probe outside the aquarium. - Wireless temperature monitoring: the mini aquarium temperature meter lets you monitor your water habitat remotely without obstructing the view or disturbing aquatic life. - Use scenarios: - In a home freshwater or marine aquarium, mount the sensor outside the tank with suction cups for quick temperature checks and clear viewing. - In a display or office setup, use the wireless/adhesive option to keep the tank glass clean while you continuously monitor water temperature. - For ongoing accuracy, replace the LR44 when needed to ensure consistent readings from the external probe.
