Five Types of Aquarium Thermometers

Aquarium thermometers allow you to monitor the temperature in your fish tank. There are many different types of thermometers that you can use. Some of these include floating, stick-on, and wireless remote. This article will...

Floating

One of the first types of aquarium thermometers is the floating design. They are constructed of plastic and are designed to float around the tank. If you want, you can also attach them to the inside of the tank using a suction cup. Some floating aquarium thermometers can also measure the salinity of the tank. One of the main problems with floating thermometers is that they can be difficult to read while they're floating around.

Stick-on

One of the next types of aquarium thermometers is the stick-on variety. These thermometers are simply mounted on the outside of the tank. They are very easy to use and inexpensive. Stick-on aquarium thermometers also don't require you to search for the thermometer like you would with floating designs.

Wireless Remote

One of the more expensive types of aquarium thermometers is the wireless remote design. You install a plastic probe on your tank, then mount a display device anywhere that you want. These aquarium thermometers are very convenient. Some designs will allow you to have up to four display devices. There are also designs that will sound an alarm when a high or low temperature has been reached.

Digital

There are also digital aquarium thermometers. They are attached to the exterior of the aquarium using a stainless steel mount. These aquarium thermometers are usually powered by batteries and monitor the temperature using a probe that is placed in the tank. They are easier to read than some other types and are easy to use also.

Standing

One of the final types of aquarium thermometers is the standing design. These thermometers are designed to stay at the bottom of your fish tank. They are weighted so that they don't float to the top of the water. These aquarium thermometers can be difficult to find and read, especially if there is a current in the tank.

These are the different types of aquarium thermometers. Stick-on thermometers are inexpensive and easy to read. Wireless remote aquarium thermometers are very convenient as you can have up to four display devices to monitor the temperature. Some designs will even have an alarm that will sound when high or low temperatures have been reached.
