About This

• This 2-in-1 bundle features a high-accuracy submersible thermometer with calibration capability and a magnetic cleaner equipped with a temperature sensor. Monitor your aquarium's temperature in two convenient ways—via the always-visible thermometer display or the cleaner's built-in sensor—ensuring reliable, consistent readings for a stable aquatic environment.
• The submersible thermometer offers both 24/7 always-on and customizable timer modes, with adjustable screen brightness for day and night viewing. The magnetic thermometer allows one-touch temperature unit switching (℉/℃). Both devices are designed for effortless daily use.
• The thermometer is fully submersible with a sealed circuit board and ultra-low voltage operation (5V). Together with the floating magnetic cleaner, both are built to perform safely in freshwater or saltwater setups without disrupting tank inhabitants.
• The submersible thermometer conducts direct, high-precision, and continuous measurements through a probe immersed in water. It features a calibration function and an always-on screen to ensure temperature stability. In contrast, the aquarium magnetic thermometer has a sensor on the back of the brush, which requires contact with the glass to measure temperature. This makes it more suitable for quick temperature checks during cleaning, serving as a supplementary or instant reference tool.
