Over-the-Rim Glass Thermometer
Sleek, clean, and stylish, this over-the-rim glass thermometer looks great on a rimless planted aquarium and lets you monitor the temperature without drawing too much attention to itself.
Can also be used for rimmed tanks less than 15mm wide. For tanks with wider rims, you may need to shave off a bit of the overhanging black lip.
Markings are in Celsius.
