Displays an accurate temperature of the water inside your tank with its tiny probe.

The major benefit of this thermometer is that it has an alarm on it to warn of too high or too low a temperature.

You are able to adjust the high and low levels so that should the water temperature raise or drop below your set level, an alarm will sound. This is an incredibly useful feature that could save your entire stock.

It also displays your room temperature, and has a back lit display. Ideal for any fish tank.

Can also be used in the home as a general room thermometer.
