Digital thermometers consist of a probe that is placed in the aquarium water, either permanently or temporarily, which connects to a digital display outside the tank. Some connect wirelessly, while others have a cord that physically attaches the probe to the display.
Generally, these models require batteries to operate, although a few high-end models plug into the wall outlet. The sensor probe is usually attached to the display, which can be unsightly. A few models place both the sensor and display inside the tank. With these, there is a risk of battery leakage in the tank.
Some models provide an audible alert feature that will sound an alarm when the temperature falls below or above the desired range. Most lower priced models do not provide an alert, nor do they display in more than one scale. When choosing a style, check the probe cord length, as it varies from model to model. As with other types of thermometers, the temperature ranges that can be read also varies. Keep in mind that although these models are usually fixed in one spot, you can easily move them to take a reading in a problem area of the tank.
