Aquarium Thermometers

Aquarium Thermometers are essential for keeping your fish, live plants and corals, happy and health in your tank. Almost all fish and plants, and all coral, require specific temperatures to remain in peak health in the wild. We can use aquarium thermostats to replicate the natural environment for our fish to ensure a long, healthy, and happy life. As a result, this small device is essential for most tanks and fish owners.

The Aquarium Factory stocks a wide range of thermometers from the best brands in Australia and around the world. Many of our thermometers also allow you to check the temperature inside the tank with precise accuracy, without needing to remove the thermometer or placing your hands in the tank, potentially contaminating the tank.

A Quality Thermometer is Essential for Optimal Conditions

A good thermometer should be easy to read and lack mercury, which could harm your aquatic animals. The Aquarium Factory stocks glass and adhesive aquarium thermostats, which conveniently stick to the outside of your tank. We also have digital options, which provide a continuous reading of your aquarium’s temperature.

In any situation, it’s important to have the right thermometer for the needs of your unique tank. Warm temperatures ranging from 25°C to 30°C are just right for most tropical fish. This is really important because these types of fish will not be able to survive without the right water temperature. Room temperature and the aquarium water all have an impact come in to play and need to be measured.

How to Use Aquarium Thermometers

If you own an aquarium, then you will need to have an aquarium thermostat on hand. An aquarium thermometer is a device that is used specifically to measure the temperature of the water environment inside your aquarium. There are actually several different kinds of aquarium thermostats available. While all aquarium thermostats perform the same function, there are actually several different kinds of aquarium thermostats that have different features attached to them. Knowing the different kinds and how they work will be very helpful for you if you are looking for an aquarium thermometer. Feel free to explore our range of products and find the one that suits your needs.

There are many reasons why people invest in aquarium thermostats. In order to keep an eye on the temperature of your aquarium, an aquarium thermometer is a must-have tool that you should get, even if you only use it on rare occasions. However, thermometers in an aquarium should be used in a consistent manner so as not to disrupt its ecosystem. In order to do that, you should get the best aquarium thermostats available.

Basically, there are two different types of aquarium thermostats: mechanical analog and digital thermometer options. Mechanical analog fish tanks thermometers are those that have been round and rectangular shaped with a marked grid on its top and bottom. These types work well with tropical fish tanks as they are sensitive to high temperatures and tend to freeze up more quickly than their digital counterparts. LED thermometer models are very handy and reliable, as they are easy to read and have a digital display. As a result, it is no surprise that LED thermometer varieties are becoming very popular and are great for ensuring water temperature is within the safety zone. Again room temperature and aquarium water temperature do change and need to be monitored.

Digital aquarium thermometer models, on the other hand, are those thermometers that have an integrated circuit that continuously measures the temperature of the tank. However, the thermometer measures the fish tank’s temperature through a digital display that contains an anode and a cathode. The anode is typically a red led diode while the cathode is a black lead element that generates heat when exposed to electric current. When the current passes through the anode, it causes the cathode to turn on, releasing energy that is radiated outwards towards the aode’s surrounding surface. Compared to mechanical thermometers, digital fish tank thermometers provide greater accuracy and are easier to use in freshwater aquariums.
