Battery-Powered Aquarium Thermometer – Black/White

Description

This compact digital thermometer provides a simple way to monitor aquarium water temperature. The current CJ source lists a 1.5 V supply, a remote-probe design, dimensions of 48 × 28.5 × 15 mm and a measurement range of -50 to 110 °C. Black and white options are listed on the DaraSphere product page.

Using it with an aquarium

Place only the intended sensor or probe in the water; keep the display housing and battery compartment dry unless the manufacturer explicitly marks them as waterproof. Position the probe away from a heater outlet, strong light or a cold draft so the reading better represents the main water volume.

Allow the reading to stabilise and compare it with a trusted reference thermometer before relying on it for sensitive livestock. CJ lists accuracy as ±1 °C, but individual units and probe placement can affect the result. This device measures temperature; it does not heat, cool or control the aquarium.

Care and safety

• Inspect the probe cable and casing for damage before use.
• Replace the battery when the display becomes weak or erratic, using only the specified type and correct polarity.
• Keep batteries away from children and pets and dispose of used batteries responsibly.
• Do not use this aquarium item for medical decisions.
