ADA Nature Aquarium Thermometer White type J-05 (for an aquarium 5mm in thickness).
ADA Nature Aquarium Thermometers are the most beautiful thermometers available. They are superbly designed to be elegant, simple, exquisite and highly discrete. The addition of an ADA thermometer makes a huge difference to the overall look of any aquascape.
Their slender bodies are made from glass and are designed so that they can be placed directly onto a wall of your aquarium without detracting from your aquascape or disturbing the beautiful scene you have created.
ADA NA thermometers are available with a clear rear side or a white rear side so that the temperature scale is more visible whilst maintaining high levels of discretion.
