An accurate and easy to read glass thermometer. Features a suction cup that allows the thermometer to be attached to the interior of the aquarium. Suction cup can be easily removed for use as a free-floating thermometer. Has a green safety zone indicator to show the best temperature range for most tropical fish. Each thermometer measures approximately 4" tall. Range: 0 to 40 degrees C and 40 to 100 degrees Fahrenheit. For fresh or saltwater use.
I've always found these units to be just a bit off because of the placement of the number (temperature) scale. Once you know how much its off, you can deal with it and simply watch for changes up or down.
These things are dirt cheap. Stick it where you want it in the aquarium and your done. My only problem with them is in some cases the printout is hard to read. This is easy to cure since you can see them in the pack before buying them.
