A round temperature display for the outside of a tank
This round digital thermometer sits against the outside of an aquarium wall and shows the reading in large green digits. The gallery identifies a TD-01A model, a USB-C charging connection and a measurement range stated as −9.9°C to 50°C.

- Celsius and Fahrenheit displays pictured
- USB-C charging connection
Everyday use
The dark circular face keeps the readout visually separate from the aquarium behind it. A touch-control symbol appears beneath the digits, and the slim side view shows the charging port. The intended arrangement avoids an immersed display or loose probe cable inside the water.
A visible readout
Large green numbers are shown on a dark background in both Celsius and Fahrenheit examples.
External mounting
The feature images describe measurement from outside the tank wall.
Rechargeable format
A USB-A to USB-C cable and the charging port are pictured with the thermometer.

Choosing and caring for yours
Clean and dry the intended outside mounting area, and follow the supplied placement instructions for the tank material. Allow the reading to settle and compare it with a suitable reference thermometer when setting up or investigating a temperature problem. Keep the charging port dry and do not immerse the display. This device reports a temperature reading; it does not control a heater or guarantee suitable conditions for every species.
